AI Voice Agent
An AI agent with a real-time voice interface that can both listen and respond in natural speech.
Voice agents are the next major surface for AI after text chat. Real-time voice models (OpenAI's Realtime API, Google's Live API, Anthropic streaming) plus high-quality TTS (ElevenLabs, Play.ht) made human-sounding voice interactions production-grade in 2025.
Production use cases: customer support that resolves tickets without a human, AI receptionists for restaurants and clinics, language tutors, accessibility tools, and outbound sales (use ethically many regions require disclosure).
Latency is the hardest engineering problem. Sub-500ms turn-taking is the threshold for feeling natural; getting there requires streaming throughout the stack, careful interruption handling, and often parallel ASR/LLM/TTS pipelines.
