What is Low Latency TTS?

Low latency text-to-speech refers to AI voice generation systems that produce audio output in under 200 milliseconds from the time text is received. This is critical for real-time applications like conversational AI agents, live gaming, phone systems, and interactive voice assistants where delays feel unnatural to users.

Why Latency Matters: The 200ms Rule

Human conversation flows naturally with response times under 200ms. When AI agents take longer, users perceive hesitation or lag, breaking immersion. Research shows that delays over 500ms make bots sound robotic and hurt user satisfaction by up to 60%.

How MorVoice Achieves Sub-100ms Latency

MorVoice uses WebSocket streaming instead of HTTP REST APIs, eliminating connection overhead. Our 'Turbo-Socket' protocol streams audio bytes while the neural network is still processing, achieving TTFB (Time to First Byte) of 68ms compared to competitors' 240-650ms. This makes real-time AI conversations feel natural.

Use Cases for Low Latency TTS

Critical applications include: AI phone agents for customer support, real-time translation services, gaming NPCs with dynamic dialogue, voice-enabled chatbots, virtual assistants (Alexa, Google Assistant alternatives), and live audio dubbing for broadcasts.
