    I Benchmarked 5 Voice AI Stacks. Only 2 Stayed Under 300ms.

    A recent benchmark of five voice AI stacks revealed that only two consistently responded under the critical 300ms latency threshold. The author found that voice-to-voice end-to-end models, which collapse STT, LLM, and TTS into a single process, significantly outperformed cascaded pipelines. These cascaded systems struggled to meet the latency demands due to serial processing of speech-to-text, LLM time-to-first-token, text-to-speech, and network round-trip times. The two fastest stacks were OpenAI's Realtime API with GPT-4o and LiveKit Agents with Google's Gemini 2.0 Flash. AI
