Anthropic is expanding Claude’s voice capabilities as competition in AI assistants intensifies, allowing users to choose between its Opus, Sonnet and Haiku models in voice mode. The update comes just weeks after OpenAI introduced a new family of conversational models and refreshed ChatGPT’s voice experience.
A More Capable Voice Experience
Until now, Claude’s voice mode relied exclusively on the Haiku model, prioritizing speed over more complex conversations. With the latest update, users can switch between Opus, Sonnet and Haiku while speaking with Claude, while voice mode automatically defaults to the fastest version of the model most recently used in text chat. The change creates a smoother transition between typing and speaking and is designed to support more demanding tasks, including preparing client presentations, refining communication and brainstorming product ideas, Anthropic said.

Voice That Works Across Apps
Beyond expanding model choice, Anthropic is also extending Claude’s ability to work across third-party services. Voice mode can now connect with Gmail, Google Calendar, Slack, Canva and Notion, allowing users to reschedule meetings, draft emails or create documents without leaving the conversation.
The update also sets Claude apart from many competing voice assistants by extending conversations into workplace tasks through connected applications, rather than focusing solely on natural dialogue.
Multilingual Support
Anthropic has also been broadening Claude’s reach. Earlier this year, the company added beta support for multiple languages, allowing users to speak in English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese and Spanish, although the language must currently be selected manually. The expansion is aimed at teams operating across multiple regions and languages.
Availability
The updated voice mode is now available in beta across platforms. Free users can access only the Haiku model and connect a single app, while paid subscribers can choose between all three models and use additional integrations.
Anthropic did not announce changes to the underlying voice model or disclose the technology powering the feature. It also did not say whether the update includes improvements to conversational behavior, such as interruption handling.
