SoundHound AI, an AI-powered voice technology platform, has been sued after allegedly misleading investors with false statements regarding its accounting practices.
The lawsuit comes as leading AI firm OpenAI continues to face its own wave of legal challenges, highlighting the increasing legal scrutiny across the AI industry.
On Thursday, April 3, OpenAI won a bid to consolidate several high-profile copyright lawsuits into a single case.
The law firm Kessler Topaz Meltzer & Check filed the class action lawsuit on Thursday, April 3, claiming that SoundHound failed to fully disclose issues with its financial reporting, mainly related to the accounting of its corporate acquisitions.
The AI firm allegedly gave the impression that it had resolved weaknesses in its internal financial controls, while in reality, it had not taken sufficient action.
On March 4, 2025, SoundHound disclosed that it could not file its 2024 financial report on time due to “the complexity of accounting for” its previously announced acquisitions of Synq3 and Amelia Holdings.
“SoundHound overstated the extent to which it had remediated, and/or its ability to remediate, the material weaknesses in its internal controls over financial reporting,” the law firm stated in the filing notice.
“As a result of the foregoing material weaknesses, SoundHound’s reported goodwill following the acquisition of Amelia Holdings, Inc. in August 2024 was inflated and required correction,” it added.
On March 11, 2025, SoundHound released its full-year 2024 financial report and admitted that, as of the end of 2024, the company did not have proper systems in place to handle complicated financial situations, the lawsuit alleges.
The law firm claims that SoundHound likely needed more time and resources than initially expected to properly manage the accounting for the two companies it acquired—Amelia Holdings and Synq3.
However, instead of informing investors about these risks, the company continued making public statements that the law firm now alleges were misleading.
The ongoing challenges and lawsuit has led to the company’s stock falling by nearly 15% over the past month.
Kessler Topaz Meltzer & Check has urged SoundHound investors “who have suffered significant losses” to contact the firm for more information.
On Thursday, April 3, a U.S. judicial panel in New York approved the consolidation of multiple copyright cases filed against OpenAI by authors, news organizations, and entertainment industry figures.
Several lawsuits filed in California—including those brought by comedian Sarah Silverman and other writers—have now been moved to a federal court in Manhattan.
These cases will join similar lawsuits already filed there by The New York Times and authors such as George R. R. Martin and John Grisham.
Last year, OpenAI petitioned the judicial panel to consolidate 12 lawsuits into one, arguing that the cases involved “the same underlying allegations: that OpenAI used plaintiffs’ copyrighted works to train certain large language models.”
Most plaintiffs opposed consolidation, stating their cases were too distinct to be combined. Nevertheless, the judges sided with OpenAI’s request.
“We welcome this development and look forward to making it clear in court that our models are trained on publicly available data, grounded in fair use, and supportive of innovation,” an OpenAI spokesperson said.
