Overview
- Anthropic updated Claude’s voice mode on Thursday, July 23, 2026, to let users pick between the Haiku, Opus, and Sonnet models for spoken interactions.
- By default voice now uses the last text model a user selected and runs its fastest variant, and users can switch models during an active voice session.
- Voice mode can connect to third-party apps such as Gmail, Google Calendar, Slack, Canva, and Notion, allowing voice-driven actions like drafting emails and moving calendar events; free accounts are limited to Haiku and one connected app.
- The feature set includes support for 11 languages but requires users to manually select the language they want to use.
- Anthropic said it did not change or disclose its underlying voice stack with this release, so low-level behaviors like interruption handling, latency, and privacy trade-offs may remain unchanged and should be monitored as voice shifts toward workflow use.
