Voice AI Development

• Build and deploy real-time conversational voice agents, working across the speech stack — speech-to-text, LLM reasoning, and text-to-speech, as well as newer speech-to-speech approaches.

• Develop simulation capabilities that generate and role-play patient conversations at scale, covering the range of real-world conditions and edge cases that manual test
