Utterance Split

Utterance Split detects pauses between words in submitted audio. Used when the Utterances feature is enabled for pre-recorded audio.

utt_split float Default: 0.8

Pre-recorded Streaming All available languages

Deepgram’s Utterance Split feature monitors incoming audio and detects when a sufficiently long pause is detected between words. By default, the length of time Deepgram uses for Utterance Split is 0.8 seconds, but you can configure this value using the utt_split parameter.

Enable Feature

To enable Utterance Split, when you call Deepgram’s API, add an utt_split parameter in the query string and set it to the length of time (in seconds) of silence between words after which Deepgram will decide that a new utterance should begin. The default values is 0.8 s.

utt_split=LENGTH-OF-TIME-IN-SECONDS

To transcribe audio from a file on your computer, run the following curl command in a terminal or your favorite API client and define the utterance split value you’d wish to use:

cURL
$curl \
>  --request POST \
>  --header 'Authorization: Token YOUR_DEEPGRAM_API_KEY' \
>  --header 'Content-Type: audio/wav' \
>  --data-binary @youraudio.wav \
>  --url 'https://api.deepgram.com/v1/listen?utterances=true&utt_split=LENGTH-OF-TIME-IN-SECONDS'

Replace YOUR_DEEPGRAM_API_KEY with your Deepgram API Key.
