The story
Anthropic is expanding Claude's voice mode to include the Opus and Sonnet models, according to TechCrunch and The Verge. The feature was previously powered by Claude Haiku and is now available with three model options in beta across platforms, with Claude using the last model a user engaged with in text chat and defaulting to the fastest version of that model.
The company positions Sonnet and Opus as deeper models designed for hard problem-solving, capable of delivering more complex responses and taking action on user prompts. In practice, users can have voice conversations that slip into more involved tasks, including turning a chat into a one-page pitch or adjusting calendar appointments when plans change.
Anthropic also notes that Claude's voice mode can connect to external apps such as Gmail, Google Calendar, Slack, Canva, and Notion, enabling tasks like updating a meeting slot, drafting an email, or creating a document in Notion through voice commands. This marks a notable difference from OpenAI's voice mode, which has emphasized conversational style without tool integrations, according to TechCrunch.
Language support for voice mode has expanded beyond English. The Verge reports that languages available in voice mode now include French, German, Spanish, Hindi, Indonesian, Italian, Japanese, Korean, and Portuguese, with English included as part of the lineup. The Verge also notes a correction: the feature launched in 2025, not 2026.
On availability, the latest update is described as a beta across platforms, with free users restricted to Haiku and only one connected app. TechCrunch also notes that Anthropic has not announced changes to the underlying voice stack.
