TELEPHONY BOT APIs
Telephony Bot APIs (formerly RTC callback APIs) enable  developers to build voice bots & speech IVRs over SIP/RTP. We support combining an open conversational experience with a directed dialog in bots. Our JSON commands (to play a prompt,  recognize an utterance) may be invoked using web callbacks from any popular language. We integrate with NLU engines like RASA & Dialoglfow for intent capture and CPaas platforms like Twilio & Signalwire for SIP/RTP.

COMMAND AND CALLBACK APIs

Invoke commands to play a prompt or convert an utterance to text. Access results and provide commands using Callbacks.

APP LOGIC IN ANY LANGUAGE

Developers can write app logic in a programming language of their choice – Python, Node.js or Java - anything that supports JSON 

SIMPLICITY OF INTEGRATION

Telephony Bot APIs are simple to integrate. You invite us to a single session for the entire duration of the call.

SUPPORT BOTH NLU AND DIRECTED DIALOG

We integrate with popular NLU engines like RASA and Dialog-flow. We also offer easy options to specify directed dialog logic.

LARGE VOCABULARY,
SPEECH GRAMMARS

We support both large vocabulary and speech grammars. You can use grammars  to constrain the recognizer for high accuracy & simpler intent capture.
