RTC SPEECH-TO-TEXT CALLBACK API
Voicegain Realtime Communication (RTC) Callback APIs allow backend web developers to build interactive voice apps (Voice Bot, Speech IVR, phone system) in a language of their choice. You can establish a single realtime audio session with our Speech-to-Text engine; after which your code interacts using JSON commands and callbacks. We support SIP/RTP and WebRTC to better tolerate poor network connections.
