Post-call Transcription by Vonage Is Now in Beta! Feedback Requested
The Vonage Video post-call transcription API is out of Early Access and is now in Public Beta. That means that you can now use the feature without needing to be granted access beforehand.
Post-call transcription is a feature of the Vonage Video API that uses artificial intelligence and state-of-the-art technologies to generate a text transcript of a recorded video call. When enabled, the API creates a transcription file after an archive recording is complete and provides it as a downloadable JSON file.
While the Video API will return the transcription of the meeting, how you use it is up to you! Post-call transcription can help with improved record keeping, improved customer service, increased productivity, better data analysis, or whatever you can create, such as:
Facilitate note-taking of lectures, webinars, and workshops.
Analyze sales calls.
Document customer feedback and testimonials.
Generate meeting summaries and action items.
Create a searchable database of recorded interviews.
To experience this new feature, we have created a sample application that can be quickly set up and run.
For your custom video applications, to enable transcription, you set the hasAudio and hasTranscription parameters to true in the body of the REST API call when starting an archive via the REST API. The transcription becomes available once the recording is complete and is returned as a compressed ZIP containing a structured JSON file. Each file includes:
Channel-specific audio transcriptions
Confidence scores and word-level timing
Formatted and raw transcript segments
An example of enabling transcription from a CURL request:
application_id="12345abc"
json_web_token="jwt_string" # replace with a JSON web token
data='{
"sessionId": "1_MX40NzY0MDA1MX5-fn4",
"hasAudio": true,
"hasVideo": true,
"hasTranscription": true,
"name": "archive_test",
"outputMode": "individual"
}'
curl \
-i \
-H "Content-Type:application/json" \
-X POST \
-H "Authorization: $json_web_token" \
-d "$data" \
