What is speech-to-speech AI?

Speech-to-speech (S2S) is an AI architecture where speech goes directly from the caller to an AI-generated spoken response — without going through text as an intermediate step. The result is much lower latency and more natural conversation flow.

Why S2S is better than STT + TTS

Traditional systems convert speech to text (STT), send the text to an AI, get a text response, and convert back to speech (TTS). Each step takes time. S2S eliminates the intermediate step and delivers response times under 300 milliseconds — faster than a human reacts.

What does this mean for customer service?

With S2S the conversation feels natural. No noticeable delay, no robotic speech. The customer feels they are talking to a human. This leads to higher satisfaction and longer, more productive conversations.
