Voice AI
An AI system built on a three-layer architecture comprising automatic speech recognition (ASR), large language model-based natural language understanding (LLM), and text-to-speech synthesis (TTS). It is used to replace or assist human agents in handling phone calls, supporting natural language interaction and automated business processes.

Timeline (last 90 days)
Some vendors have compressed perceived latency to within 500 milliseconds through streaming processing, but it remains difficult to consistently meet this target in complex query scenarios.
Barge-in is a critical interaction mechanism that voice AI must address in real-world calls, requiring real-time monitoring of the user's intent to interrupt while the AI is speaking and a millisecond-level decision on whether to stop.
Voice AI has demonstrated practical value in structured, predictable scenarios such as bill inquiries, appointment confirmations, and status tracking.
Human-AI collaboration—where AI handles low-complexity calls and complex calls are transferred to human agents—is a more pragmatic deployment model for voice AI.
The key to judging whether a voice AI system is mature lies in whether it can recognize the boundaries of its capabilities and transfer to a human agent in a timely manner when it makes errors, rather than in how smoothly it performs when things go well.
