In a significant move highlighting the intense competition for top talent in the burgeoning artificial intelligence sector, Google DeepMind has announced a new licensing agreement that brings on board the CEO and several key engineers from the voice AI startup, Hume AI. Alan Cowen, Hume AI's CEO, along with approximately seven other engineers, will join DeepMind to specifically enhance the voice features of Google's advanced AI model, Gemini. This strategic "acqui-hire," first reported by Wired, allows Google to integrate specialized expertise in empathetic voice technology directly into its core AI development.

While the financial terms of the deal were not disclosed, Andrew Ettinger, who recently assumed the role of CEO at Hume AI, confirmed to TechCrunch that Google has secured a non-exclusive right to Hume AI's intellectual property. This arrangement allows Hume AI to continue operating independently, supplying its technology to other AI firms, and even releasing new models in the coming months. Ettinger also shared ambitious projections, stating that Hume AI is on track to generate $100 million in revenue this year, building on the close to $80 million it has already raised.

This acqui-hire by Google DeepMind is emblematic of a broader trend within the AI industry, where leading firms are increasingly acquiring teams rather than entire companies. This tactic allows them to secure highly sought-after talent and proprietary technology while potentially navigating around the rigorous regulatory scrutiny often associated with full corporate acquisitions. Similar instances include Google's acquisition of Windsurf's CEO and researchers last year, and OpenAI's recent assimilation of teams from startups like Convogo and Roi. The Federal Trade Commission (FTC) has taken notice of this trend, indicating a forthcoming closer examination of such deals.

The deal also underscores the rapidly growing importance of voice as a critical frontier in artificial intelligence. Hume AI's core innovation lies in its models' sophisticated ability to discern a user's emotions and mood through their voice, a capability demonstrated by its Empathetic Voice Interface, a conversational AI launched in 2024. This emotional intelligence in AI is becoming a significant differentiator in human-computer interaction.

Beyond Hume AI, major tech giants and specialized startups are heavily investing in voice-focused AI models. Google itself has been steadily refining its Gemini Live feature, which enables fluid conversational interactions with its chatbot. Last month, Google rolled out a new native audio model for the Live API, significantly improving the model's capacity to manage complex workflows. OpenAI is reportedly preparing a substantial overhaul of its audio models in anticipation of launching an audio-first personal device, developed in collaboration with Jonny Ive’s io, potentially in the form of earbuds, later this year. Meta has also accelerated its AI audio initiatives, notably through the acquisition of Play AI last year, and is integrating advanced voice and audio features into its Ray-Ban smart glasses to assist with tasks such as enhancing conversations in noisy environments and offering hands-free control.

The surging demand for sophisticated voice capabilities is evident across the industry. Investor Vanessa Larco emphasized the necessity of voice for wearables, stating, "Voice is the only acceptable input mode for wearables," and predicted that the Google-Hume deal would accelerate the need for voice applications. Further demonstrating market demand, ElevenLabs, a prominent AI voice generation startup, recently announced it had surpassed $330 million in annual recurring revenue. This landscape confirms that voice AI is not just a niche but a central pillar in the next generation of artificial intelligence interfaces and applications.
