Anthropic has updated Claude’s voice mode to allow users to select between Opus, Sonnet, and Haiku models, a shift from the previous single-model constraint. The earlier version, powered by Haiku, prioritised speed but struggled with complex tasks. This new update defaults to the fastest version of the model used in text chat, aiming to support longer conversations, feedback on communication style, and brainstorming for market research. The feature also integrates with external applications including Gmail, Google Calendar, Slack, Canva, and Notion. Users can now request actions such as updating meeting slots, drafting emails, or creating documents within these tools. OpenAI’s voice mode remains limited to conversational style changes without direct tool access. Multilingual support is available in beta for ten languages, though users must manually specify the language. The update is accessible to all beta users, although free accounts are restricted to the Haiku model and one connected app. Anthropic did not alter the underlying voice model, meaning users may not experience improved conversational features like better interruption handling compared to recent OpenAI releases.
- Free users are limited to the Haiku model with only one connected app.
- Manual language selection is required despite multilingual support.
- No changes were made to the voice synthesis stack.
