Numerals

numerals boolean Default: false

Pre-recorded Streaming English (all available regions)

Deepgram’s Numerals feature converts numbers from written format to numerical format. For example, the number "nine hundred" would appear in your transcript as "900".

⚠️
This feature is available for English only (all available regions).

Enable Feature

To enable numerals, when you call Deepgram’s API, add a numerals parameter set to true in the query string:

numerals=true

To transcribe audio from a file on your computer, run the following cURL command in a terminal or your favorite API client.

ℹ️
Be sure to replace the placeholder YOUR_DEEPGRAM_API_KEY with your Deepgram API Key. You can create an API Key in the Deepgram Console.

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?numerals=true'

Toggling Numerals during a real-time stream

In addition to the query string parameter, if you're sending real-time streaming data, you can turn Numerals on or off at any point during the stream. To do so, send the following JSON message to the websocket:

{
  "type": "Configure",
  "features": {
    "numerals": true (or false)
  }
}

Numerals can be turned on and off multiple times during a stream if desired.
