# Claude's voice mode now available for Opus and Sonnet models Anthropic adds voice feature to advanced AI models. - **Source:** [The Verge](https://www.theverge.com) - **Published:** 2026-07-23 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/a45d9f44-7f4d-4df3-b87a-d04dc53ac809 ## The Evolution of Voice AI Anthropic initially launched Claude's voice mode only with the Haiku model, designed for quick responses. Users adopting this feature beyond expectations and using it to solve business problems prompted the company to extend it to more powerful models. ## Opus and Sonnet Difference Unlike Haiku, Opus and Sonnet models can perform complex analyses and execute tasks on behalf of users. For example, they can turn a conversation into a one-page proposal or automatically reschedule your calendar if your train is delayed. ## Flexible User Experience Users can now switch between text and voice modes within a single conversation. They can also transition between different models. A simple chat started with Haiku can be deepened by switching to Opus. ## Multilingual Support Originally available only in English, voice mode now supports nine new languages including French, German, Spanish, Hindi, Indonesian, Italian, Japanese, Korean, and Portuguese. This expansion significantly increases the AI's global reach. ## Integration Breadth Anthropic aims to streamline daily workflows by integrating voice mode with popular business applications like Gmail, Slack, and Canva. These integrations make AI's contribution to work productivity more tangible. ## AI's Role in Business Claude's new features demonstrate that AI can now play an active role in complex business processes beyond answering simple questions. This development represents a significant step forward for workplace automation. ## Sources covering this story - https://www.theverge.com/ai-artificial-intelligence/970065/anthropic-voice-mode-claude-opus-sonnet-haiku-ai — --- _Summary written by Brifing from the original reporting.
