AI voice cloning opinion narrows claims to ROP, rejecting TM and (most) copyright theories

Lehrman v. Lovo, Inc., --- F.Supp.3d ----, 2025 WL 1902547, 24-CV-3770 (JPO) (S.D.N.Y. Jul. 10, 2025)

Plaintiffs alleged that Lovo misled them about its use of their voices, using AI to synthesize and sell unauthorized “clones” of their voices. They sued for violations of New York civil rights and consumer protection laws, the Lanham Act, and the Copyright Act, along with common-law contract, fraud, conversion, unjust enrichment, and unfair competition claims. Lovo was partially successful on its motion to dismiss, but had to deal with the NY ROP claims, as well as consumer protection and breach of contract claims. I might not agree with every detail of the extensive opinion, but this is a useful map of the issues. It’s also a reminder of the hazards of not contracting properly with people you don’t employ.

Plaintiffs Lehrman and Sage are voice-over actors. Lovo “sells a text-to-speech subscription service that allows its clients to generate voice-over narrations at a fraction of the cost of the traditional model.” It claims that its software, Genny, was “created using ‘1000s of voices.’ ” Genny is allegedly capable of creating a voice “clone,” which “refers to a virtual copy of a real person’s voice.” It advertised its voice cloning service by emphasizing how similar its cloned voices are to the originals from which they are derived. In one marketing video, Lovo stated, “you will hear five speakers whose voices have been cloned to near perfection. Their tone, accent, and even mannerisms are fully learned by our AI voice system.” One of Lovo’s co-founders described a cloned voice as a replacement for “a real human voice,” allowing users of Lovo’s platform to “make that voice say anything that you want, even if that person has never actually said that before in their life.”

Lovo advertises the commercial use of its platform to “Save $$ and time on voiceovers.” Allegedly, “Lovo represents to its customers that Lovo is granting full commercial rights for all content generated using its platform to users who subscribe to any of its paid plans,” which cover “any monetized, business-related uses such as videos, audio books, advertising, promotion, web page blogging, [and] product integration.”

Lovo originally solicited Lehrman and Sage for the projects relevant to this action on an online marketplace for freelance services called Fiverr. A Lovo employee allegedly contacted Lehrman and hired him to “provide voice recordings for ‘research purposes,’” assuring him that the company would use the recordings for “research purposes only,” and that such research would be only “internal” and “academic” in nature. Lehrman wrote back, asking for a “guarantee that these scripts will not be used for anything other than your specific research project,” to which the employee replied: “The scripts will not be used for anything else ....” The employee further confirmed that the script would not be “repurposed and used in a different order.” He was paid $1,200 for his work.

Similarly, Sage asked what the proposed recordings would be used for, and the Lovo rep (a principal) replied: “These are test scripts for radio ads. They will not be disclosed externally, and will only be consumed internally, so will not require rights of any sort.” Sage asked him to to confirm that the recordings would not be used “in broadcast,” and he again repeated the previous statement. Lovo paid Sage $400 for her work.

Both of them ultimately (after filing suit) registered their scripted performances with the Copyright Office.

Plaintiffs allegedly first learned that their voices had been used in unanticipated ways when they listened to an episode of the Deadline Strike Talk podcast narrated in part by an artificial voice produced by Lovo’s software. They alleged that the voice used in the podcast was “identical to Mr. Lehrman’s voice.” Allegedly, “[n]umerous people who heard the podcast,” including “friends” and “professional colleagues” “told Mr. Lehrman or Ms. Sage” that the “voice on the podcast was virtually identical to Mr. Lehrman’s voice,” and that “the cloned voice would undoubtedly be mistaken for Mr. Lehrman’s actual voice.” They also alleged, with declaration support, that professionals “experience[d] [in] discerning and conveying small differences in voice tone, quality, timbre, and delivery” believe that “Lovo’s cloned voice is a replica of Mr. Lehrman’s real voice.” Lehrman allegedly found that Lovo “had been marketing [the clone of his voice] as part of its subscription service under the stage name ‘Kyle Snow.’ ” The Kyle Snow voice was also in advertisements on Lovo’s website and YouTube. For example, Lovo allegedly advertised the Kyle Snow voice as “an ideal male voice generator ... for all kinds of content” due to his “upbeat tone and slightly faster talking speed.”

Sage also allegedly discovered that Lovo had created a clone of her voice named “Sally Coleman” that was available to Lovo’s subscribers. This was allegedly marketed using “side-by-side” comparisons of Sage’s original audio recordings—the ones she provided via Fiverr—and the “cloned version of her voice,” including in an investor pitch that was posted on YouTube. 

Plaintiffs brought individual claims and also sought to represent a voice actor class and a consumer class of consumers who bought the Lovo software and used the voices.

Breach of contract: Sufficiently pled.

Lanham Act false association: Failed for want of a mark that was used as a mark. Plaintiffs didn’t argue that they could bring §43(a)(1)(A) claims without a valid mark. Persona can be a “mark”—even for a noncelebrity. But celebrity endorsement cases have involved “the unauthorized use of a celebrity’s likeness on merchandise, implying that the celebrity approves of the merchandise or is affiliated with the seller,” or “the explicit use of a celebrity’s likeness in advertising or to promote goods or services.”

Plaintiffs alleged that “they are well-known and sought-after voice actors whose voices are their recognizable calling cards,” which was enough at this stage to make the use of their voices capable of causing consumer confusion. The problem was that the allegations didn’t suggest trademark use. “Because marks can take essentially any form, courts must therefore be careful to ensure that they receive protection only when used as contemplated by the statute—that is, as marks.” The court found celebrity endorsement cases to be an “uneas[y]” fit with this principle, “as celebrities’ personas are also their products,” though at least for advertising cases the service of endorsement seems like the trademark use. Citing Jennifer Rothman, the court emphasized that “personal marks” are treated differently from other marks—they’re harder to register, and the law “is highly skeptical of efforts to restrict individuals from using their own identities in trade” and doesn’t allow “transfer attributes of one’s identity—such as personal skill as an artisan—when one transfers trademark rights in one’s name or likeness.” [My own view is that the latter point isn’t really relevant—it’s just not possible to do that; maybe that means that many name transfers are transfers in gross and should fail, but that is straying pretty far from our concerns here.]

The key issue here was that this wasn’t a celebrity endorsement case: the voices were themselves the products/services being sold. “Plaintiffs here use their voices in ways that are clearly separable from their identities and personalities. Their clients pay them to produce recordings of themselves narrating scripts, which the clients then own and use to produce content, as authorized by their contracts with Plaintiffs.” Thus, their voices “serve dual functions as both ‘one of the most palpable ways identity is manifested,’ and as ordinary services in the voice-over market.” Thus, even as to the alleged false endorsement or “business affiliation” confusion, plaintiffs’ voices were “protectable only to the extent that they function primarily as source identifiers rather than as products themselves.” The court analogized to trade dress product design claims, which are difficult because trademark terminology “is unsuited for application to the product itself.”

Plaintiffs failed to show that their voices were protectable marks. They didn’t plead secondary meaning or the relevant factors except for “a few conclusory references to the recognizability of their voices” and the fact that “Plaintiffs’ work has been sought out by large companies.” Regardless, “Plaintiffs have not alleged that their voices are primarily significant as brands rather than as services to which brands might be attached.” As the court noted, “even extremely famous celebrities are barred from asserting Section 43(a)(1) claims based on the use of their likenesses as products rather than as source-identifying marks.” Product use was descriptive use, not trademark use. An alternate rule would threaten a new voice actor “whose voice happens to sound highly similar to either Lehrman’s or Sage’s,” especially given that identicality isn’t required for likely confusion. The court also pointed out that unregistered trademark rights can be assigned, with “unsettling” consequences for voices:

To allow any artist, actor, or other creative tradesperson to sue their doppelgangers for trademark infringement, as Plaintiffs’ theory would allow, would “create[e] a cause of action for, in effect, plagiarism,” and would be incompatible with the careful ways that courts have circumscribed the Lanham Act to avoid unduly burdening competition and free expression. [Citing Dastar.]

Lookalike cases involving ads involve “appropriating the identity and the goodwill of the famous plaintiffs—that is, pretending to be Woody Allen—rather than merely engaging in the same trade while happening to look like the famous plaintiffs.” And, the court noted, Allen’s cases involved use of identity in ads, not his lookalike’s presence as part of a good or service. “To allow Plaintiffs to protect the downstream uses of their voices merely because Plaintiffs originated them would disrupt the ‘carefully crafted bargain’ struck by patent and copyright law and ‘misuse’ the Lanham Act to ‘to reward [artisans] for their innovating in creating a particular [work or] device.’”

What we’re seeing, post-JDI, is the further development of a “use as a mark” doctrine to cabin trademark’s nearly unchecked expansion, unfortunately mostly without discussion of the relevant considerations and how they relate to the purposes of trademark law. That’s present here, yay! It would be great for more courts to admit that this not an entirely empirical assessment, or at least it’s only empirical at the categorical level. (See also the pre-JDI Louboutin v. YSL case, the standout entry in the “ipse dixit use as a mark” cases.) In addition, JDI’s language about how even partial TM use is bad is, as has always been apparent, complete nonsense (in the absence of a materiality requirement).

False advertising: Two theories here. First, plaintiffs alleged that marketing their voices under the names “Kyle Snow” and “Sally Coleman” was literally false. The court disagreed: “Plaintiffs point to numerous examples of Lovo marketing the voices as what they truly are—synthetic ‘clones’ of real actors’ voices.” Also, Lovo falsely allegedly stated that the cloned voices “came with all commercial rights.” But even if that’s true, “such misrepresentations do not concern ‘the nature, characteristics, qualities, or geographic origin’ of Plaintiffs’ cloned voices.” (Dastar.)

Second, plaintiffs alleged that Lovo “confus[ed] potential customers ... as to [Plaintiffs’] affiliation with Lovo and the ability to use the Lovo service in place of traditional access to these actors,” and that Lovo “misrepresent[ed] that [Plaintiffs] have partnered with Lovo.” Those were not actionable as false advertising; they were repeats of the false affiliation claim, and “Plaintiffs cannot avoid the requirement of a protectable mark by ‘disguis[ing] a § 43(a)(1)(A) trademark infringement and unfair competition claim as a false advertising § 43(a)(1)(B) claim.’”

In addition, plaintiffs failed to identify any false implication or consumer confusion from Lovo’s advertising, “as opposed to being confused by the similarity of the synthetic voices to Plaintiffs’ voices when heard in the wild. In fact, Plaintiffs actually allege that Lovo’s advertising was clear on the lack of connection between Plaintiffs and Lovo’s voice clones.”

Even if Lovo made misrepresentations, plaintiffs didn’t plead actual injury. Where “the defendant and plaintiffs are competitors in the same market,” materiality and injury usually blend together, but plaintiffs didn’t allege that their losses were related to actionable false claims in Lovo’s advertising. Instead, their losses were allegedly due to the existence of Lovo’s product: “Put differently, Lovo’s services are more desirable to some customers because they are cheaper and more accessible. While Plaintiffs might have a different cause of action for such competitive harm, it does not sound in Lanham Act false advertising.”

Copyright: Four claims, only one of which goes forward. The court approved of the sequence (1) complaint filed without any copyright claims, (2) registration secured, (3) complaint amended to add copyright claims as consistent with Fourth Estate, and I think I agree, since (1) was far from a sham complaint. The discovery rule applied for statute of limitations purposes,

Contractual defenses couldn’t be resolved on a motion to dismiss, even without taking into consideration the chat messages exchanged by the parties. Turns out, Fiverr’s TOS provide special rules for “Voice Over Gigs” “that are inconsistent with a transfer of unrestricted copyrights.” Despite a general work for hire clause, the TOS stated that buyers of voice-over recordings are only “purchasing basic rights, ... allowing them to use the work forever and for any purpose except for commercials, radio, television and internet commercial spots.” Buyers need to purchase higher-tier packages of either “Commercial Rights,” in order to “promote a product and/or service,” or “Full Broadcast Rights,” in order to use the recordings “in radio, television and internet commercials.” Lovo didn’t do that.

First, Sage successfully pled a direct infringement claim based on Lovo’s use of her actual voice recording in an investor presentation, pitches to investors, at a conference, and in Lovo’s external marketing materials. (Although this is for later, the fair use defense for comparative advertising is a distinct subset of copyright fair use cases where defendants generally win. How else are they supposed to substantiate their claim of being as good as a human?)

Both plaintiffs alleged direct infringement based on Lovo’s use of their recordings to train the Genny AI model. These claims failed “for lack of adequate explanation in the complaint.” They didn’t explain “what training is or how it works, even at a very high level of generality. The Court therefore cannot ascertain or reasonably infer which exclusive rights Lovo allegedly infringed, or how.” But amendment was possible, including using information-and-belief pleading. (On the other hand, it might be hard to plead what was outside the scope of the license, even as modified by the chats.)

Copyright infringement by the AI outputs: Here there was really no hope. Sound recording copyright only covers exact duplication of the fixed sounds, which was not alleged here as even a possibility for Genny. And we know that a voice isn’t copyrightable, since that’s what gives them their valid ROP claims.

Contributory infringement: based on AI outputs, therefore failed.

NY ROP: Although NY’s ROP is narrower than other states’, and only covers uses in, essentially, advertising, there was enough here to proceed. (Query how much of plaintiffs’ damage comes from the advertising and not the underlying product; also, later on the incidental use defense—advertising for a product that does not itself violate the ROP is protected where the advertising actually relates to the product—may come into play.)

The statute of limitations is one year, but the republication exception can restart the limitations period, and applied here. But are digital replicas even covered? Lovo argued that NY’s 2021 statutory protection for digital replicas of deceased persons meant that expressio unius applied to exclude that from the main ROP. But that reasoning ignored context. “Just before the amendment was proposed, New York courts held that digital replicas of living persons—at least ones with a visual component—were already covered by the law. There is no indication in the text of Sections 50 and 50-f, or in the legislative history, that the amendment was intended to overturn this precedent, nor to exclude the possibility of a similar holding with respect to audio-only voice clones.” The same could be true of voice. “If anything, the Court views ‘voice’ as having a broader scope than a term like ‘picture,’ because it cannot plausibly be read to refer to any particular form of media or representative device. While Section 51’s statutory ROP “is to be narrowly read” in light of its legislative history, it is nonetheless “not to be obeyed grudgingly by construing it narrowly and treating it as though it did not exist for any purpose other than that embraced within the strict construction of its words.”

As to the substance, plaintiffs sufficiently alleged recognizability and Lovo itself allegedly represented that its creations are “practically indistinguishable from the ‘real’ voice.” While “New York courts have consistently dismissed Section 51 claims based on the use of a fictitious name, even if the depiction at issue evokes some characteristics of the person or the person is identifiable by reference to external sources,” “those cases all involve a fictional character sharing certain discrete attributes or traits with a Section 51 plaintiff, not the use of the plaintiff’s portrait or voice.” “Lovo cannot escape liability merely because it appended fictitious names to those appropriated voices. To hold otherwise would carve out a massive, judicially created loophole in the statute with no textual or doctrinal basis.”

Plaintiffs also adequately alleged use in both advertising and trade. “Advertising purposes has been defined as use in, or as part of, an advertisement or solicitation for patronage of a particular product or service, and trade purposes involves use which would draw trade to the firm,” although the statute doesn’t reach newsworthy uses or matters of public interest. Lovo didn’t raise a First Amendment, newsworthiness, or public interest defense.

The court is a little wobbly on whether the underlying product itself counts as “trade” purposes, though my reading of the NY cases is that it can’t (emphasis added to last sentence):

Whether or not the solicitation of investors itself counts as an “advertisement,” the function of the “investor presentation, which was later posted publicly online, is plausibly understood as promoting Lovo’s underlying product. The same goes for the use of Lehrman’s voice in tutorials and promotional articles posted online. Moreover, even if the voices were not used in formal advertisements or solicitations, they were clearly used for commercial purposes, and to draw trade to the firm. It is plausible to infer that, by illustrating the value of the product and helping show prospective customers how to use it, Lovo used its publicly posted tutorials to increase the appeal of its software, acquire subscribers, and retain subscribers it already had. Plaintiffs allege even that Lehrman’s cloned voice was Lovo’s default product and one of its self-described “best” voices.

NY GBL: Partially survives, raising an interesting Dastar preemption issue. Section 349 prohibits “[d]eceptive acts or practices in the conduct of any business, trade or commerce or in the furnishing of any service” and Section 350 prohibits “[f]alse advertising in the conduct of any business, trade or commerce or in the furnishing of any service.”  “To successfully assert a claim under either section, ‘a plaintiff must allege that a defendant has engaged in (1) consumer-oriented conduct that is (2) materially misleading and that (3) plaintiff suffered injury as a result of the allegedly deceptive act or practice.’ ”

Mostly, plaintiffs failed to identify material misrepresentations to the public; they couldn’t rely on misrepresentations to them because they were not acting as consumers in those transactions, and Sections 349 and 350 do not reach such “narrow, private dispute[s].”

However, plaintiffs adequately alleged that Lovo materially misrepresented the scope of the “commercial rights” that it promised to provide to its subscribers, thereby making its offerings appear more attractive. Lovo’s consumers thus “purchased ... [but] did not receive a product with the full value with unlimited usage rights, which would have been a product with legitimately acquired and/or created voices.” Sections 349 and 350 aren’t limited to “nature, characteristics, qualities, or geographic origin.”

Note: While statutory interpretation got us Dastar, if it’s true that extending the Lanham Act to licensing claims would cause a conflict with copyright law, it’s equally true that extending state law to licensing claims would cause a conflict with copyright law, creating conflict preemption. Cf. Jackson v. Roberts (finding preemption of a ROP claim). But the court says that plaintiffs “could not bring a similar GBL claim based on alleged misrepresentations about a copyright license, as such a claim would be preempted by the Copyright Act.” I am not sure about the difference between advertising “commercial rights” or “unrestricted use” and advertising “properly licensed,” but ok.

“Lovo promised its subscribers that they could use Lovo’s voice clones without legal restrictions. While Lovo was correct with respect to federal copyright and trademark law, it was incorrect with respect to New York law. Lovo’s consumers could, like Lovo itself, be liable under Sections 50 and 51 of the NYCRL.” [Again, the language here is open, but I would argue that the only liability for customers would have to be for their own uses in advertising/trade.]

Lovo’s conduct with respect to its subscribers was “consumer oriented” in that it was “directed to consumers” and had “a broader impact on consumers at large.” Although the mere unauthorized use of the plaintiffs’ images would not be “ ‘consumer-oriented in the sense that it potentially affects similarly situated consumers,” reselling the voices to third-party consumers for downstream use by those consumers was relevantly different.

And plaintiffs adequately alleged that they suffered injury from Lovo’s misrepresentations in the form of diverted customers and lost sales. “While it is true that Lovo offered its voice clones at lower prices than the services of traditional voice actors, Lovo was able to poach Plaintiffs’ customers only because it purported to offer products that its subscribers could legally use—that is, because it engaged in misrepresentations made unlawful by Sections 349 and 350.”

Fraud claims failed because (1) plaintiffs didn’t adequately plead damages; although they alleged customer diversion/harm to brand value, they didn’t quantify the “true value of the recordings they sold to Lovo, as opposed to what Lovo paid,” which is the measure of fraud damages in NY, and (2) their fraud claims merely restated their breach of contract claims, which isn’t ok in NY “when the only fraud alleged is that the defendant was not sincere when it promised to perform under the contract.”

Unjust enrichment, conversion, and common law unfair competition claims were preempted by the New York Civil Rights law, which preempts “all common law claims based on unauthorized use of name, image, or personality, including unjust enrichment claims.” Relatedly, unfair competition is like the failed Lanham Act claims (except also requires bad faith), and there were no facts alleged “supporting an inference that Lovo acted with the intent of generating confusion or coopting Plaintiffs’ reputations (as opposed to the desirable characteristics of their voices).”
