Unverified语音Agent延迟优化应从优化最佳情况平均TTFA转向优化真实区域分布和并发压力下的最坏情况一致性74% similarUnverifiedEach time a TTS (Text-to-Speech) speech synthesis system is called, the model's random sampling may cause subtle drift in timbre, manifesting as inconsistencies in details such as speaking rate, intonation, and resonance characteristics.73% similarUnverifiedA typical TTS system response chain contains three key stages: text preprocessing, acoustic model inference, and vocoder synthesis.73% similarUnverifiedIn voice dialogue systems, the LLM inference step requires the time to first token (TTFT) to be kept within 200 milliseconds; otherwise, users will noticeably perceive a pause.73% similarUnverifiedTraditional TTS systems require recording hours of voice data to train a speaker-specific model.70% similar
