Claude voice mode adds Opus and Sonnet — Anthropic ends its Haiku-only voice era

Anthropic upgraded Claude voice mode so users can talk to Opus and Sonnet, not only Haiku. All plans get the change; paid tiers add mid-conversation model switching, more connected apps, and beta support for non-English languages.

Anthropic's voice mode can finally reach beyond Haiku to Opus and Sonnet, so voice conversations get the same models people already trust for text.

What is it?

Claude voice mode is a spoken conversation interface inside the Claude mobile, desktop, and web apps. From 23 July 2026, users pick between Opus, Sonnet, and Haiku instead of being locked to Haiku — the model Anthropic first shipped with because it kept latency low.

How does it work?

Voice mode inherits the model from the user's last text chat and defaults to its fastest variant, so a person mid-Opus conversation gets Opus in voice too. Paid users can swap models mid-call. Voice can also read from Gmail, Google Calendar, Google Docs, and Slack when the account has the connector enabled.

Why does it matter?

Opus and Sonnet unlock use cases the Haiku-only voice mode routinely stumbled on — pitch practice with real feedback, brainstorming an investor deck, working through a legal clause. Free-tier users get the upgrade too, though limited to one connected tool at a time.

Frequently asked questions

Which plans get Claude voice mode?
Claude voice mode is available across Free, Pro, Max, Team, and Enterprise plans in beta. Free plans can connect one tool at a time. Paid plans can connect more tools and switch models mid-conversation without restarting the call.
Which apps can Claude voice mode connect to?
Claude voice mode connects to Gmail, Google Calendar, Google Docs, and Slack, so users can ask the assistant to summarize a mailbox thread, adjust a meeting, pull a doc, or check a channel while driving or walking. Free tier users can attach one connected tool at a time.
How is the new voice mode different from the old one?
The prior Claude voice mode routed every request through Haiku, the smallest and fastest model, which struggled on complex questions. The new voice mode lets users pick Opus or Sonnet for harder work, and inherits the last text model used so conversations start on the tier the user already trusts.
Is Claude Fable available in voice mode?
Claude Fable is not currently available in voice mode; Anthropic's supported models for voice are Opus, Sonnet, and Haiku. Users who want Fable's stronger reasoning still need to type. Anthropic's docs mention Fable support may arrive later but do not give a date.
