Anthropic is getting ready to introduce a new “voice mode” feature that could rival OpenAI’s similar option within ChatGPT, according to Bloomberg. The AI voice assistant will reportedly live within its Claude AI chatbot and could start rolling out “as soon as this month.”

According to Bloomberg, Anthropic plans to roll out three English-language voices called Airy, Mellow, and Buttery. This isn’t the first time we’ve heard about a potential voice mode. Anthropic’s chief product officer, Mike Kreiger, spoke about it in an interview with the Financial Times last month. “We will do voice internally, too; it is a useful modality to have. We have prototypes,” Kreiger said at the time.

The app researcher M1Astra initially uncovered references to voice mode in Anthropic’s iOS app, which Bloomberg says it later confirmed. The Verge reached out to Anthropic with a request for comment but didn’t immediately hear back.

Anthropic, founded by former OpenAI employees, has become a major competitor for the maker of ChatGPT. The company recently launched a $200 / month tier for “power” users and also announced a new research-focused AI tool on Tuesday.
