Anthropic expands Claude voice mode to Opus and Sonnet models

Anthropic has expanded its voice mode feature to its more advanced AI models, Claude Opus and Claude Sonnet, after initially launching it only on the faster but less capable Haiku model. The company also announced that voice mode is now integrated into third-party applications including Gmail, Slack, and Canva, broadening its accessibility for users.

The expansion affects current and potential users of Claude’s premium models, particularly professionals and businesses who rely on the AI for complex tasks. Voice mode was originally designed for quick, casual queries, but Anthropic observed that users quickly adopted it for more substantial work, such as solving real business problems. The Haiku model, optimized for speed, was not well-suited for these deeper interactions, prompting the company to bring voice capabilities to its more powerful models.

This matters because it allows users to engage with Claude’s most capable AI through natural speech for demanding applications, potentially improving productivity in professional settings. By integrating with popular productivity tools, Anthropic is positioning Claude as a versatile assistant that can be used hands-free within existing workflows.

According to a blog post by Anthropic, the voice mode was launched earlier this year on Haiku. The company did not specify an exact date for the new expansion, but the announcement was made in a recent post. No specific user numbers or performance metrics were provided.

Background: Anthropic initially released voice mode on Claude Haiku to prioritize low latency for simple questions. However, user behavior shifted toward using voice for more complex, business-oriented conversations, revealing a gap that the new expansion aims to fill.

Looking ahead, the company is likely to monitor how users interact with voice mode on Opus and Sonnet, potentially guiding future updates or further integrations. No specific next steps were outlined in the source.
