Several weeks after OpenAI upgraded the voice functionality of ChatGPT, Anthropic announced on July 23, 2026, a significant update to the voice mode of its AI assistant, Claude. Users can now freely switch among three models—Opus, Sonnet, and Haiku—and the update supports seven languages, including Chinese and Spanish. The voice interaction now features a hands-free mode and a press-to-talk mode, and a phone handset icon has been added to the iOS app, hinting at the possibility of a more phone call-like interaction experience in the future.
