Claude mobile voice mode getting a major upgrade:

• 18 language support with seamless switching mid-conversation

• 1-2 new voice options per language

• Redesigned voice UI with push-to-talk functionality

• Still powered by Claude Haiku 4.5 under the hood

• Architecture remains text-to-speech (not native voice model)

Technically interesting: they're sticking with TTS pipeline rather than going full end-to-end voice like GPT-4o. Haiku 4.5 handles the reasoning layer, then outputs get synthesized. Trade-off is latency vs model control.

Rollout looks imminent based on the teaser. 👀
