Anthropic has released an upgrade to voice mode for its Claude AI model family, aiming to make the feature more useful across a wider range of user tasks.

The updates, announced in a July 23 blog post, are intended to help Claude provide more assistance in several scenarios, particularly for people using the chatbot in workplace settings. The move broadens voice mode beyond quick back-and-forth exchanges and brings it closer to the same model choices users already have in text chat.

Until the update, Claude’s voice mode ran on Haiku, the company’s smallest model, which Anthropic selected for speed. The company said that approach supported fast interactions but limited conversational depth. “It kept conversations quick, but not always deep,” Anthropic said.

Anthropic has now extended voice mode to Claude’s Opus and Sonnet models. The feature automatically uses the model that a user most recently selected for text chat, while also allowing users to switch models during a conversation.

According to Anthropic, voice mode will operate on the fastest version of whichever model the user chooses, supporting more natural conversations. The company said the upgraded feature can deliver notably improved performance in situations such as giving feedback on communication style, helping with pitches and brainstorming ideas.

The update also adds support for interacting by voice with connected third-party apps, including Gmail, Slack, Canva and Google Calendar, provided the capability has been enabled in settings. Anthropic said this allows users to make voice requests to reschedule meetings in their calendars, turn a conversation about a client pitch into a one-page document in Canva, or ask Claude to summarize emails received during a defined period and draft replies to the most important messages. That integration is a key part of the workplace use case, because it lets voice interactions move beyond answering questions and into actions across tools where users already manage messages, meetings and documents.

Voice mode now supports 11 languages. In addition to English, Claude can handle voice conversations in French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese, Spanish and Latin American Spanish.

However, users who want to change languages in the middle of a conversation must either tell Claude to switch or adjust their settings. Anthropic said voice mode cannot yet automatically detect language changes.

The upgraded voice mode is available in beta to all Claude chat users on mobile, desktop and web. For users on the free plan, the feature is limited to Haiku and one connected third-party tool, although all supported languages are available. Paid plans include access to all connected tools and all supported models, with voice conversations counting toward usage limits.
