Anthropic has upgraded Claude’s voice mode with support for its more capable Opus and Sonnet model families, expanding the feature beyond Haiku and giving paid users a stronger option for complex spoken tasks, connected apps and multilingual conversations.
TL;DR
- Claude voice mode can now use Opus, Sonnet or Haiku, depending on the user’s plan.
- It begins with the model most recently used in text chat.
- Voice conversations can use connected tools such as Gmail, Google Calendar, Google Docs and Slack.
- The beta is available on Claude’s web, desktop, iOS and Android experiences.
Anthropic released the update recently, more than a year after introducing voice mode in 2025. Until now, spoken conversations were powered only by Haiku, the company’s faster model designed for quick responses.
The Verge reported that users pushed voice mode beyond short questions and began using it to work “through real business problems.” Anthropic acknowledged that Haiku “kept conversations quick, but not always deep,” prompting it to add Sonnet and Opus.
What Changes With Opus And Sonnet?
Claude voice mode now starts with the model a user last selected in text chat and automatically uses the latest generation of that model. Users can also switch between Haiku, Sonnet and Opus during an ongoing conversation.
Anthropic’s support documentation says the upgrade lets voice mode handle harder questions rather than only rapid exchanges. Context carries across text and voice, allowing users to type a precise detail, switch to speech and continue without restarting.
TechCrunch said the stronger models are suited to longer, work-focused interactions, including reviewing communication styles, rehearsing client pitches and brainstorming product-market research. The Verge added that Claude could turn a spoken discussion into a one-page pitch or adjust calendar appointments when travel plans change.
The update does not replace Anthropic’s underlying voice technology. TechCrunch noted that the company did not announce improvements to areas such as interruption handling or disclose details about the voice stack powering the experience.
Claude Voice Mode Gets Connected Apps
Voice mode can use connected services, including Gmail, Google Calendar, Google Docs and Slack, when the user grants access. This allows Claude to summarize emails, check schedules or review a Slack thread during a spoken conversation.
TechCrunch also listed Canva and Notion among the available integrations. Users may ask Claude to draft an email, update a meeting or create a document without leaving voice mode.
Anthropic says free users can connect one tool, while paid plans can connect more. TechCrunch reported that free users remain limited to Haiku, whereas Sonnet and Opus access follows the models included with a user’s subscription.
Where Is The Upgraded Voice Mode Available?
The beta is available across Claude on the web, desktop, iOS and Android. Spoken conversations count toward the regular usage allowance attached to each plan.
Claude supports voice conversations in English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese and Spanish. Users can select a preferred language in settings or ask Claude to switch languages during a conversation.
Topics for more insights:
CNET described the release as a sizable upgrade because it brings spoken interactions closer to the intelligence available in Claude’s text interface. However, the larger differentiator may be tool use, as Claude can combine voice instructions with connected workplace apps.
By extending Opus and Sonnet into voice mode, Anthropic is positioning Claude as more than a hands-free chatbot. The update makes speech a practical interface for deeper analysis and multi-step work, although model access and limits still depend on the user’s plan.
