# Key Features

### `domain`

This field identifies your use case type and set of the terminology defined for transcription. e.g. for general audio is ‘generic’. Refer to [Supporting Domain](/usage-guides/speech-to-text/supported-domains) to see the available domains.

**For Example**:

<CodeGroup>
  ```bash generic theme={null}
  curl --location --request POST 'https://revapi.reverieinc.com/upload' \
  --header 'src_lang: hi' \
  --header 'domain: generic' \
  --header 'REV-API-KEY: <YOUR API KEY>' \
  --header 'REV-APPNAME: stt_batch' \
  --header 'REV-APP-ID: <YOUR API-ID>' \
  --form 'file=@"<File Path>"'
  ```

  ```bash bfsi theme={null}
  curl --location --request POST 'https://revapi.reverieinc.com/upload' \
  --header 'src_lang: hi' \
  --header 'domain: bfsi' \
  --header 'REV-API-KEY: <YOUR API KEY>' \
  --header 'REV-APPNAME: stt_batch' \
  --header 'REV-APP-ID: <YOUR API-ID>' \
  --form 'file=@"<File Path>"'
  ```
</CodeGroup>

### `format`

The audio sampling rate and the data format of the speech. Refer to [Supporting Audio Formats](/usage-guides/speech-to-text/supported-audio-formats) to know the supporting audio formats. By default, the `format` = 16k\_int16. (WAV, Signed 16 bit, 16,000 or 16K Hz).

**For Example**:

<CodeGroup>
  ```bash format = 16k_int16 theme={null}
  curl --location --request POST 'https://revapi.reverieinc.com/upload' \
  --header 'src_lang: hi' \
  --header 'domain: generic' \
  --header 'REV-API-KEY: <YOUR API KEY>' \
  --header 'REV-APPNAME: stt_batch' \
  --header 'REV-APP-ID: <YOUR API-ID>' \
  --header 'format: 16k_int16' \
  --form 'file=@"<File Path>"'
  ```

  ```bash format = wav theme={null}
  curl --location --request POST 'https://revapi.reverieinc.com/upload' \
  --header 'src_lang: hi' \
  --header 'domain: bfsi' \
  --header 'REV-API-KEY: <YOUR API KEY>' \
  --header 'REV-APPNAME: stt_batch' \
  --header 'REV-APP-ID: <YOUR API-ID>' \
  --header 'format: wav' \
  --form 'file=@"<File Path>"'
  ```
</CodeGroup>

### `subtitles`

Enables subtitling from the audio file.

**For Example**:

<CodeGroup>
  ```bash subtitles = true theme={null}
  curl --location --request POST 'https://revapi.reverieinc.com/upload' \
  --header 'src_lang: hi' \
  --header 'domain: generic' \
  --header 'REV-API-KEY: <YOUR API KEY>' \
  --header 'REV-APPNAME: stt_batch' \
  --header 'REV-APP-ID: <YOUR API-ID>' \
  --header 'subtitles: true' \
  --form 'file=@"<File Path>"'
  ```

  ```bash subtitles = false theme={null}
  curl --location --request POST 'https://revapi.reverieinc.com/upload' \
  --header 'src_lang: hi' \
  --header 'domain: bfsi' \
  --header 'REV-API-KEY: <YOUR API KEY>' \
  --header 'REV-APPNAME: stt_batch' \
  --header 'REV-APP-ID: <YOUR API-ID>' \
  --header 'subtitles: false' \
  --form 'file=@"<File Path>"'
  ```
</CodeGroup>

**Response**:

<CodeGroup>
  ```json subtitles = true theme={null}
  {
      "job_id": "e21f356d-cbf9-4d62-a960-1e9da1805d19",
