Constructor

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

Usage

Batch Transcription

The transcribe method can receive the url to a file or a buffer with a file to transcribe. Additional options can be provided to customize the result.

const response = await deepgram.transcribe(URL_OR_BUFFER_OF_FILE, {
  punctuate: true,
  // other options are available
});

Options

{
  // AI model used to process submitted audio.
  model?: "general" | "phonecall" |  "meeting" | "<custom-id>",

  // BCP-47 language tag that hints at the primary spoken language.
  // Defaults to en-US
  language?: "en-GB" | "en-IN" | "en-NZ" | "en-US" | "es" | "fr" | "ko" | "pt" | "pt-BR" | "ru" | "tr" | null,

  // Indicates whether to add punctuation and capitalization to the transcript.
  punctuate?: true | false,

  // Indicates whether to remove profanity from the transcript.
  profanity_filter?: true | false,

  // Maximum number of transcript alternatives to return.
  // Defaults to 1
  alternatives?: integer,

  // Indicates whether to redact sensitive information, replacing redacted
  // content with asterisks (*).
  redact?: ["pci", "numbers", "ssn"],

  // Indicates whether to recognize speaker changes.
  diarize?: true | false,

  // Indicates whether to transcribe each audio channel independently.
  multichannel?: true | false,

  // Indicates whether to convert numbers from written format (e.g., one) to
  // numerical format (e.g., 1).
  numerals?: true | false,

  // Terms or phrases to search for in the submitted audio.
  search?: [string],

  // Callback URL to provide if you would like your submitted audio to be
  // processed asynchronously.
  callback?: string,

  // Keywords to which the model should pay particular attention to boosting
  // or suppressing to help it understand context.
  keywords?: [string],

  // Indicates whether Deepgram will segment speech into meaningful semantic
  // units, which allows the model to interact more naturally and effectively
  // with speakers' spontaneous speech patterns.
  utterances?: true | false,

  // Length of time in seconds of silence between words that Deepgram will
  // use when determining where to split utterances. Used when utterances
  // is enabled.
  // Defaults to 0.8 seconds
  utt_split?: number,

  // Mimetype of the source
  // Mimetype is required if the provided source is a buffer
  mimetype?: string,
}

Response

Key Management

List Keys

Retrieve all keys using the keys.list method.

const response = await deepgram.keys.list();

Response

{
  keys: [
    {
      key: "API KEY",
      label: "KEY LABEL",
    },
  ];
}

Create Key

Create a new API key using the keys.create method with a label for the key.

const response = await deepgram.keys.create("label for key");

Response

{
  key: "API KEY",
  secret: "API SECRET",
  label: "LABEL PROVIDED"
}

Delete key

Delete an existing API key using the keys.delete method with the key to delete.

await deepgram.keys.delete("key to delete");

Samples

A sample js file is in the sample directory. To run it, update the config located at the top of the file.

const config = {
  deepgramApiKey: "Your Deepgram API Key",
  deepgramApiSecret: "Your Deepgram API Secret",
  urlToFile: "Url to audio file",
};

The sample demonstrates the following uses:

• Transcribing a file from a url
• Creating an API key
• Deleting an API key
