**[Claude Voice Integrated with Opus and Sonnet: Schedule Changes and Email Drafts at Your Command]** According to monitoring by Beating, Anthropic has upgraded Claude's voice mode. Paid users can now choose between Opus, Sonnet, and Haiku, rather than being limited to the faster but less capable Haiku. Users can switch models during conversations or opt to use text at any time. Claude defaults to the model selected during the previous text chat and utilizes the fastest version within that series. The voice mode can also integrate with Gmail, Google Calendar, Google Docs, and Slack. Users can instruct Claude to check emails, modify schedules, or draft replies, with authorization requested before execution. The new version is now available for testing on mobile, desktop, and web platforms. Free users are limited to Haiku and one connection tool. Voice mode currently supports multiple languages, including English, Japanese, and Korean, but does not yet include Chinese. This upgrade primarily enhances model inference and tool integration capabilities. Anthropic has not replaced the voice model, so the naturalness of speech and interruption handling may not show significant changes. [Original Link]
