In a significant move within the artificial intelligence industry, Google DeepMind has acquired the core team from voice AI startup Hume AI. As part of a new licensing agreement, Hume AI’s CEO, Alan Cowen, and approximately seven of its top engineers will join DeepMind. Their focus will be on enhancing the voice features of Google’s Gemini AI.
The remaining portion of Hume AI will continue to operate, licensing its technology to other AI companies. No financial details of the arrangement were disclosed.
This transaction represents the latest example of a major AI firm acquiring a startup’s talent rather than the entire company, a strategy that often avoids deeper regulatory scrutiny. Last year, Google similarly brought on the CEO and researchers from the viral AI coding startup Windsurf. OpenAI has also acquired multiple startup teams in recent months, including those from Covogo and Roi. The Federal Trade Commission has recently indicated it will scrutinize such talent acquisition deals more closely.
The deal underscores that advanced voice interaction is becoming a key frontier in AI development. Hume AI’s distinguishing technology is its model’s ability to interpret a user’s emotions and mood through vocal tone. The startup launched its Empathetic Voice Interface in 2024. To date, Hume AI has raised close to $80 million and, according to reports, expects to generate $100 million in revenue this year.
Hume AI is not alone in focusing on voice. Google has been consistently improving its Gemini Live conversational feature, recently releasing a new native audio model for its API. OpenAI is reportedly preparing a major overhaul of its audio models ahead of the planned launch of an audio-first device developed with Jonny Ive’s firm. Meta has also accelerated its audio AI efforts, acquiring startup Play AI last year and enhancing the voice and audio capabilities of its Ray-Ban smart glasses.
Industry observers note the growing necessity for voice technology. As one investor stated, voice is the primary input method for wearable devices, and acquisitions like this will accelerate the demand for voice-enabled applications. The market demand is clearly rising, evidenced by AI voice generation startup ElevenLabs recently reporting it surpassed $330 million in annual recurring revenue.
