Some challenges can't be solved just by typing. Today, Anthropic made a key upgrade to Claude's voice mode—it no longer runs only the lightweight Haiku model, but can now run on three models: Claude Opus, Claude Sonnet, and Claude Haiku. It also connects to tools like Gmail and Slack, and supports more languages.

This update has a reason. Earlier this year, after Claude added hands-free conversation, people quickly used the voice mode for more complex scenarios—longer conversations where they used speech instead of typing to tackle real business problems. But at that time, the voice mode only ran on Haiku, chosen for speed. The conversation was indeed fast, but often not deep enough. Now, Opus and Sonnet, designed to solve tough problems, have entered the voice mode. Users can switch models anytime using the model selector during the conversation; the voice mode will choose the fastest version of the selected model, keeping the conversation smooth, and it will default to the model you last used in text chats—so you can switch between voice and text without starting over.

With stronger models, you can now speak out ideas that are not yet fully formed, and let Claude help you develop real insights. It will ask questions, extend your thoughts, rather than give a standard answer. The voice mode works with take turns: Claude listens first, pauses to think, and then responds. Anthropic provides several scenarios worth trying—practice an important conversation and ask it to evaluate your communication style, organize a client proposal and have it identify logical flaws, brainstorm a product roadmap and ask it to do competitive research to validate, or ask it to help you evaluate different hypotheses for why "that video went viral."

Once you know what you want to do, you can let Claude execute it. If you're running late, ask it to reschedule a meeting on Google Calendar by 30 minutes; turn a client proposal conversation directly into a document in Canva; ask it to summarize today's emails and draft responses for the most important ones. Before using connected tools, Claude will request permission. New tools can be added in "Settings > Connectors" on mobile, desktop, or web.

In terms of language, voice mode now supports more languages across all plans. You can talk to it in the language you think in, and you can switch languages during the conversation. However, Claude won't automatically detect the language—you need to verbally request it or manually select it in the voice settings. Also, the language for the voice mode needs to be set separately, and previous language preferences won't be automatically carried over.

This update is now available in beta for all chat users on mobile, desktop, and web, but the experience is best on mobile. Free plans can use Haiku, one connected tool, and all supported languages; paid plans can access more models and all connected tools, and voice conversations count toward regular usage limits.
