You can't define the duration. The API will try to transcribe the entire audio file every time, not just a section.

Using the Node SDK, you could send your request with the utterances feature turned on. (e.g. utterances:true)

Then, when the transcription comes back you can use the .toSRT() or .toWebVTT() functions to generate a text based version of the transcript with timestamps. Then you'd want to save it locally using fs.

Example:

const { Deepgram } = require('@deepgram/sdk');
const fs = require('fs');

const deepgram = new Deepgram(DEEPGRAM_API_KEY)
const audioSource = { url: URL_OF_FILE };

deepgram.transcription.preRecorded(audioSource, {
  punctuate:  true,
  utterances: true,
  // other options are available
})
.then((response) => {
  const srtTranscript = response.toSRT();

  fs.writeFile(FILENAME_TO_SAVE, srtTranscript, function (err) {
    if (err) {
      return console.log(err);
    }
    console.log("The file was saved!");
  });
})
.catch((err) => {
  console.log(err);
});
Enter fullscreen mode Exit fullscreen mode

That was real quick. But I don't really want it like a subtitles file. Rather I just want the transcript text to be saved to the file and not anything else. I am talking about the sentences in that transcript: part (the one marked in purple).

You could just use the transcript property itself:

const { Deepgram } = require('@deepgram/sdk');
const fs = require('fs');

const deepgram = new Deepgram(DEEPGRAM_API_KEY)
const audioSource = { url: URL_OF_FILE };

deepgram.transcription.preRecorded(audioSource, {
  punctuate:  true,
  // other options are available
})
.then((response) => {
  const srtTranscript =response.results.channels[0].alternatives[0].transcript;

  fs.writeFile(FILENAME_TO_SAVE, srtTranscript, function (err) {
    if (err) {
      return console.log(err);
    }
    console.log("The file was saved!");
  });
})
.catch((err) => {
  console.log(err);
});
