Voicegain
Speech Analytics API

 
Voicegain Speech-to-Text canbe used for Real-Time Transcription (Live Transcription)
SPEECH ANALYTICS API
Voicegain Speech Analytics APIs allows developers to analyze audio recordings of calls, web meetings, voicemails and more. These recordings get accurately transcribed and analyzed using AI. We inspect both audio and the transcript to extract sentiment plus other metrics and entities. The annotated recordings can accessed using our our APIs. We provide a reference Web UI that can be customized by clients.
INGEST AUDIO FROM DIVERSE SOURCES

Voicegain Speech Analytics can ingest audio from diverse sources like files, object storage (e.g. S3), Web APIs, SIP/SIPREC. 

SPEECH ANALYTICS AT THE EDGE

Voicegain platform can offer control, data privacy and security by providing analytics at the Edge (i.e. on client’s infrastructure). Edge also offers lower pricing.

CUSTOM ACOUSTIC MODELS

Voicegain can train the acoustic model to include utterances related to industry jargon, speaker style and accents, etc. Custom trained models cut the word-error-rate in half.

AFFORDABLE PRICING

Voicegain is disruptively priced to analyze 100% of recordings. Why sample, when you can know it all.
Pricing is based on usage, so there are no fixed costs.

BOTH AUDIO AND TEXT 
ANALYZED BY AI

Our AI algorithms are applied both to call audio and the transcript in order to extract features like sentiment throughout the call, relevant entities, etc.
