Why turn-taking latency matters more than raw model speed
Turn-taking latency voice ai determines conversational feel more than model tokens/sec. We break down the pipeline to optimize real-time UX.
Whisper vs Deepgram: transcription latency compared
A pragmatic engineering comparison of Whisper vs Deepgram latency, cost model, and integration effort for real-time and batch transcription systems.
The hidden latency costs of voice AI pipelines
Most voice AI latency lives outside the LLM. We dissect the hidden latency costs voice ai pipeline architects overlook and how to measure them.
Measuring interruption latency in real-time voice agents
A practical analysis of how to measure interruption latency in voice agents, why component benchmarks mislead, and where to instrument the turn-taking pipeline.
How streaming TTS cuts perceived latency in voice apps
Analyze how streaming TTS reduces perceived latency in voice apps, with tradeoffs in prosody, buffering, and architecture for real-time conversational UI.
End-to-end latency breakdown for a voice AI call center bot
A practical voice ai call center latency breakdown: where milliseconds go in real-time bots, how to measure them, and which tradeoffs actually matter.
ElevenLabs vs PlayHT: text-to-speech latency benchmark
A practitioner's head-to-head comparison of ElevenLabs vs PlayHT latency, cost, and ergonomics for real-time text-to-speech engineering.
Benchmarking voice AI latency under real network conditions
A practical analysis of how to benchmark voice AI latency under real network conditions, covering test harness design, jitter, packet loss, and tradeoffs.
Benchmarking voice AI latency for IVR replacement
A practical analysis of voice ai latency ivr replacement: how to benchmark full-duplex pipelines, set latency budgets, and design fallback for production IVR.
The 300ms threshold: when voice AI feels human
Analysis of the voice ai latency threshold human feel: why 300ms matters, measurement methods, and architecture tradeoffs for real-time voice systems.
GPT-4o Realtime API latency benchmark for voice agents
A practical analysis of GPT-4o Realtime API latency for voice agents: what to measure, how to benchmark honestly, and where the real bottlenecks sit.
Cascaded vs native speech-to-speech: which is faster?
Engineer's comparison of cascaded vs native speech-to-speech latency across cost, capabilities, and ergonomics, with a verdict for real-time voice apps.
Benchmarking speech-to-speech latency across voice AI stacks
A rigorous speech-to-speech latency benchmark must isolate ASR, LLM, and TTS stages and account for fallback tail latency. This analysis shows how.
