UnverifiedTraditional TTS solutions require generating a complete audio file before playback, with latency typically ranging from several seconds to over ten seconds.74% similarUnverifiedStreaming architectures can compress end-to-end time-to-first-audio (TTFA) latency from the 1–3 seconds of serially stacked processing down to the 300–500 ms range.74% similarVerifiedThe total chain latency of traditional voice interaction is typically 3–8 seconds, whereas real-time media streaming can compress end-to-end latency to the hundreds-of-milliseconds level.74% similarUnverifiedThe time to first byte (TTFB) for streaming synthesis can typically be reduced to the level of a few hundred milliseconds.72% similarUnverifiedA streaming pipeline can compress end-to-end latency for voice AI to under 500 milliseconds, whereas the total latency of traditional batch processing can be as high as 3–5 seconds.71% similar
