A voice agent is not a chatbot with a phone number
Voice agents require real-time processing capabilities that differ significantly from typical chatbot architectures. Applying chat-based assumptions to voice interactions can lead to costly failures, such as agents engaging with each other or voicemail systems. The critical difference lies in latency tolerance; while chat allows for multi-second pauses, voice conversations have a strict perceptual budget of around 200-300 milliseconds between turns, beyond which listeners perceive a breakdown. This necessitates a different system design that can handle streaming speech-to-text, complex LLM calls, and text-to-speech generation within this tight real-time constraint, a challenge not present in asynchronous chat.
