Anthropic Upgrades Claude Voice Mode With Opus, Sonnet, and Haiku Support

Anthropic has updated Claude’s voice mode, adding support for Opus, Sonnet, and Haiku models and deeper integration with apps like Gmail and Notion.

Anthropic has rolled out a significant update to Claude’s voice mode, giving users the ability to choose between its Opus, Sonnet, and Haiku models depending on the complexity of their conversation. The update arrives shortly after OpenAI refreshed its own family of conversational models and updated ChatGPT’s voice experience.

What’s Changing in Claude’s Voice Mode

Claude’s voice mode was first introduced last year, running on the Haiku model. While Haiku offered fast responses, it wasn’t designed to handle more complex or nuanced tasks. With the new update, voice mode now automatically picks up the last model a user was working with in text chat, defaulting to that model’s fastest available version.

• Users can access Opus, Sonnet, or Haiku models through voice mode
• The system defaults to the fastest version of the last model used in text chat
• The update is designed to support longer, more detailed conversations

Built for More Than Quick Answers

Anthropic said the upgraded voice mode is meant to support tasks that go beyond simple queries. According to the company, users can now get feedback on their communication style, rehearse a pitch before meeting a client, or brainstorm ideas for product market research, all through spoken conversation.

Voice Mode Now Connects to Everyday Apps

One of the more notable additions is that Claude’s voice mode can tap into external apps, including Gmail, Google Calendar, Slack, Canva, and Notion. This means a user could ask Claude to reschedule a meeting, draft an email, or create a new document in Notion, all without switching to a keyboard.

This app integration marks a clear point of difference from OpenAI’s voice mode, which has focused on refining conversational tone and responsiveness but does not currently allow users to operate outside tools to complete tasks.

Multilingual Support Continues to Expand

Earlier this year, Anthropic introduced multilingual support for Claude’s voice mode in beta. Users can now speak in a range of languages, though they currently need to manually select the language they want to use. The supported languages include:

• English
• French
• German
• Hindi
• Indonesian
• Italian
• Japanese
• Korean
• Portuguese (Brazilian)
• Spanish (Latin America and Spain)

Availability and Access Limits

The updated voice mode is now available in beta to all users across platforms. However, free users are limited to the Haiku model and can only connect one app at a time, while access to Opus and Sonnet, along with multiple app connections, appears geared toward paid tiers.

What Hasn’t Changed

Despite the model upgrade, Anthropic did not make changes to the underlying voice model itself, and the company has not disclosed details about the voice stack it uses. This means that, unlike OpenAI’s recent release, users may not notice improvements in areas such as interruption handling or natural conversational flow. The upgrade is centered on which model powers the responses, not how the voice itself sounds or behaves.

Why This Matters

For everyday users, the update means voice mode can now be used for more substantial tasks, from planning a schedule to organizing thoughts before an important conversation. For businesses and professionals, the ability to connect Claude’s voice mode to tools like Gmail, Slack, and Notion could reduce the need to switch between apps during a workday.

As competition between Anthropic and OpenAI continues to intensify, updates like this highlight how each company is trying to differentiate its assistant, whether through tool integration or conversational polish.
