Achieving Sub-500ms Response Times in Real-Time Voice AI Agents

Human telephone conversations feel unnatural when system latency exceeds 700ms. In enterprise IVR and automated phone support, every millisecond of speech-to-speech delay impacts caller satisfaction. ### Pipeline Breakdown - **Audio Capture & Streaming**: 8kHz telephony audio streaming via bi-directional WebSockets. - **Streaming Speech-to-Text**: Token-by-token phoneme streaming to detect when the caller has finished speaking. - **Speculative Sentence Completion**: Feeding early tokens to low-latency LLM engines before full utterance completion. - **Text-to-Speech Streaming**: Instant audio synthesis streamed back to the telephony trunk in sub-chunked frames. Through these techniques, Kommify Voice AI delivers fluid, interruptible phone conversations suitable for order tracking, appointment confirmations, and tier-1 support.
