Claude Voice Mode Expands to Opus and Sonnet Models

Anthropic has made voice mode available for its Claude Opus and Sonnet models, previously limited to less capable tiers. This update brings real-time conversational audio interaction to Anthropic's most powerful publicly available models. For developers building voice-driven applications or agentic assistants, this significantly raises the capability ceiling — Opus and Sonnet's stronger reasoning and instruction-following can now be accessed through a speech interface. Teams exploring multimodal products or voice-first UX now have a compelling Anthropic-native option to benchmark against OpenAI's voice offerings. Integration details and API availability should be confirmed via Anthropic's documentation.
