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.

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.
