Claude's voice mode now runs on Opus and Sonnet, not just Haiku

In July 2026, Anthropic opened Claude's voice mode to its flagship Opus and Sonnet models. Until now it ran only on Haiku, which is fast but less capable. The company also added integrations with Gmail, Slack and Canva.

Which models now support voice

Claude's voice mode is now available on three models at once: Opus, Sonnet and Haiku. Before this update, only Haiku could talk. Haiku, Anthropic's fastest and lightest model, originally handled voice conversations with minimal latency, but it was not designed for complex tasks.

• Claude's voice mode launched in beta in 2025 and ran only on Haiku
• Since July 2026, voice is also available on Claude Opus and Claude Sonnet
• Integrations with Gmail, Slack and Canva have been added
• The reason for the expansion: users started applying voice to work tasks

Why Anthropic expanded voice

Anthropic expanded voice mode because users began using it in ways it wasn't designed for. According to the company, voice was conceived at its 2025 launch for quick answers to simple questions with minimal latency, but people almost immediately began having more serious conversations through it.

People immediately started using voice mode to work on "real business tasks,"

Anthropic says in its blog.

By the company's own admission, Haiku "kept conversations fast, but not always" up to such scenarios. The more powerful Opus and Sonnet are built for long, complex reasoning, so connecting them to voice closes that gap.

Where voice is now built in

Claude's voice mode now reaches into third-party work apps: Gmail, Slack and Canva. This means you can do more than ask the assistant questions by voice: you can work with email, team chats and a design service without switching to the keyboard.

This expansion turns voice from a reference tool into a way to run a workflow. Anthropic is betting that some office tasks are easier to delegate out loud, especially when an Opus-class model stands behind the assistant rather than only the fast Haiku.

What this means

Anthropic is turning voice mode from a quick reference tool into a full-fledged work interface. Adding the powerful Opus and Sonnet models, plus integrations with Gmail, Slack and Canva, makes voice a tool for real work, not just for short questions.
