Welcome to Symbl documentation

Symbl is a comprehensive suite of APIs for analyzing natural human conversations - both for your team’s internal conversations and of course the conversations you are having with your customers. Built on our Symbl C2I ™️ (Contextual Conversation Intelligence) technology, the APIs enable you to rapidly incorporate human-level understanding that goes beyond speech recognition and simple natural language processing of voice and text conversations.

Get real-time analysis of free-flowing discussions like meetings, sales calls, support conversations, emails, chat, social conversations, transcripts, etc to automatically surface highly relevant summary topics, contextual insights, suggestive action items, follow-ups, decisions and questions - without the use of upfront training data, wake words or custom classifiers.

Streaming API

Symbl's Streaming API is based on WebSocket protocol and can be used for real-time use-cases where both the audio and it's results from Symbl's back-end need to be available in real-time. It can be integrated directly via the browser or server.
Process live speech to text from your computer's microphone

Telephony API

Based on PSTN and SIP protocols, the Telephony API provides an interface for the developers to have Symbl bridge/join VoIP calls and get the results back in real-time as well. Optionally, the developer can also trigger an email at the end of the conversation containing the URL to view the transcription, insights and topics in a single page Web Application.
Get a transcription of your Zoom call

Async API

Symbl's Async APIs provide the functionality for processing recordings (audio/video) from files or public/signed URLs or textual content from a conversation. The data processed for these conversations is available via the Conversation APIs once the APIs have completed the processing.
