Voice Agent
An AI agent based on voice interaction that integrates components including STT (speech-to-text), LLM inference, and TTS (text-to-speech). A core challenge is reducing end-to-end latency (industry standard below 600 ms) while maintaining conversational accuracy. Voice agents are widely applied in customer service, information collection, and other complex business scenarios.
Timeline (last 90 days)
The model generates a sentence far faster than the full sentence can be played, so when the caller interrupts mid-sentence, the model's generation has long since finished, but the caller has only received part of it.
Once a response has been superseded, its remaining speech should not appear again after the caller's new request.
In production environments, the weight given to call stability is even higher than the pleasantness of the voice.
Among calls previously marked as 'resolved,' approximately half resulted in a follow-up call on the same topic within seven days.
The team added a closing confirmation step in which the agent, before ending the call, restates its understanding of the customer's need and asks whether it has been resolved, with calls that receive an uncertain answer transferred directly to a human agent.
Follow-up calls typically ended up with human agents, and customers were angrier than they had been during their first contact.
A typical failure mode of voice agents is the ability to answer questions accurately while missing the real underlying need behind the question.
