The Story

Challenge, solution, and results

The Challenge

Traditional voice AI pipelines (STT -> LLM -> TTS) introduce 1-3 seconds of latency. This makes conversations feel unnatural and leads to overlapping speech. Users hang up when AI takes too long to respond.

The Solution

Edesy integrates Gemini Live 2.5 HD for native audio-to-audio processing. No intermediate text conversion — the AI processes speech directly and generates speech output. 30 HD voices with emotional intelligence and affective dialog support.

The Results

Sub-500ms response latency — conversations feel as natural as speaking to a human. 30 HD voices across 24 languages. Affective dialog detects caller emotion and responds appropriately. Barge-in support lets callers interrupt naturally.
