Why conventional voice AI feels robotic
Traditional Voice AI Pipeline
Total: 500-800ms latency + emotion/tone lost in text conversion
Latency Issues
Each step adds processing time. 500-800ms feels unnatural in conversation.
Lost Emotion
Converting to text loses tone, pace, emphasis. The LLM never "hears" the customer.
Robotic Output
TTS converts text back to speech, adding mechanical quality to responses.
Native audio processing - no text intermediate

Common questions about how Gemini Live works
Traditional voice AI uses three separate steps: Speech-to-Text, LLM processing, then Text-to-Speech. Each step adds latency and loses audio information. Native audio AI processes the audio directly, preserving tone, emotion, and context while achieving much lower latency.
Gemini Live analyzes audio patterns that indicate emotion - speech rate, pitch variation, volume changes, pauses. It recognizes frustration, excitement, confusion, and adjusts its response tone accordingly. A frustrated customer gets an empathetic response, not a robotic one.
Gemini Live achieves under 300ms end-to-end latency on average. Traditional STT+LLM+TTS pipelines typically have 500-800ms latency. This difference makes conversations feel significantly more natural.
Each of the 30 voices has a distinct personality and speaking style. Unlike TTS voices that sound mechanical, HD voices have natural variation in pitch, pace, and emphasis. They sound like real people with consistent characteristics.
Yes, interruption handling (barge-in) is a key feature. When a user starts speaking, Gemini Live immediately stops and listens, just like a human would. It tracks context and can smoothly resume or pivot based on what the user said.
