Deepgram Flux review & benchmarks for 2026: semantic end-of-turn detection vs classical VAD, Nova-3 streaming latency, silence billing traps, and voice AI tests.
The most infuriating thing a voice AI agent can do is interrupt you mid-sentence. Or the opposite — wait 3 seconds after you stop talking before responding. Both problems trace back to the same root cause: end-of-turn detection. This is the hardest unsolved problem in voice AI engineering, and this guide explains exactly how it works, why it breaks, and the cutting-edge approaches to fixing it.
Turn detection is the single biggest reason voice AI agents either feel natural or robotic. This guide explains what turn detection is, why VAD-only approaches fail, and how modern audio-based models are solving the problem — with real-world examples and evaluation criteria.
A definitive guide on how real-time voice agents detect end-of-turn speech boundaries, prevent premature interruptions, and handle user barge-in instantly without robotic audio stutter.
