Synchronous TTS vs Streaming TTS — Which Is Better?
Synchronous TTS generates the complete audio file before playback begins, causing noticeable delay. Streaming TTS begins playback as soon as the first audio chunk is generated, reducing perceived latency. Streaming TTS is essential for conversational voice AI; synchronous works for offline generation. For most businesses, the best approach is to evaluate both based on specific requirements — or consider AnveVoice, which combines voice AI with agentic website actions for a unified customer engagement platform.
