Anthropic Revolutionizes Claude's Voice Mode with Advanced Models

Thursday, July 23, 2026, marks a significant milestone for Anthropic, which has unveiled major updates for the voice mode of its assistant, Claude. Initially limited to the Haiku model, Claude can now utilize the Opus and Sonnet models, access third-party applications like Gmail and Slack, and support ten new languages, including French.

Integration of Opus and Sonnet Models

Since its introduction in May 2025, Claude's voice mode relied exclusively on the Haiku model, known for its speed in responding to brief questions. However, Anthropic recognized that this approach was not always suited to the growing needs of users, who were seeking more complex solutions for their professional tasks.

With the addition of the Opus and Sonnet models, designed to tackle more elaborate problems, users can now choose from these options via a model selector. Anthropic specifies that the voice mode uses the fastest version of the selected model, ensuring fluidity in interactions. Furthermore, Claude retains the model used during the last conversation, facilitating a seamless transition between voice and text without interruption.

Claude's voice mode stands out for its ability to ask follow-up questions and extend the user's reasoning, rather than simply providing canned responses. It operates in turn-taking, where Claude listens, takes a moment to think, and then responds.

Interaction with Third-Party Applications

In parallel, Claude's voice mode has been enhanced to allow task execution in connected applications like Slack or Notion. For example, it can reschedule an appointment in Google Calendar, summarize received emails, or create documents in Canva. Each interaction with a third-party tool requires prior authorization, ensuring the security of user data.

Multilingual Expansion

Claude's voice mode now supports ten additional languages, broadening its global accessibility. The added languages include French, German, Hindi, Indonesian, Italian, Japanese, Korean, Brazilian Portuguese, Latin American Spanish, and European Spanish.

Language switching can be done via a voice command or through the app settings. However, Anthropic emphasizes that Claude does not automatically detect the language spoken by the user.

Beta Access and Plan-Based Options

The update was rolled out this Thursday on mobile, desktop, and web platforms, with recommended use from a smartphone. To activate the voice mode, users simply need to tap the sound wave icon in the Claude app.

The available features vary according to the subscription plan chosen by the user. The free version offers access only to the Haiku model, one connected tool, and all available languages. Paid subscriptions, on the other hand, allow access to the Opus, Sonnet, and Haiku models, as well as all connected tools.

Voice conversations are counted towards the usage quotas of each plan, encouraging users to choose their plan wisely based on their needs.
