What is Voice AI Engine?

Voice AI Engine is the speech recognition and text-to-speech engine that powers every RaylVox solution. This engine turns every word from every call into data that can be searched, analyzed, and acted upon. Unlike cloud-only solutions, Voice AI Engine integrates directly with your Asterisk PBX through AGI and AMI without additional middleware.

How Voice AI Engine Works

Receive Call Audio

Audio from Asterisk PBX is streamed in real-time to the engine via AGI script. Supports G.711, G.729, and Opus codecs.

Process & Transcribe

Acoustic models process audio into text with sub-300ms latency. Speaker diarization separates agent and customer speech.

Output & Integrate

Transcription results are sent back to PBX via AMI events. Data is available for analysis, search, and downstream integration.
