# 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**:
```bash generic theme={null}
curl --location --request POST 'https://revapi.reverieinc.com/upload' \
--header 'src_lang: hi' \
--header 'domain: generic' \
--header 'REV-API-KEY: ' \
--header 'REV-APPNAME: stt_file' \
--header 'REV-APP-ID: ' \
--form 'file=@""'
```
```bash bfsi theme={null}
curl --location --request POST 'https://revapi.reverieinc.com/upload' \
--header 'src_lang: hi' \
--header 'domain: bfsi' \
--header 'REV-API-KEY: ' \
--header 'REV-APPNAME: stt_file' \
--header 'REV-APP-ID: ' \
--form 'file=@""'
```
### `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**:
```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: ' \
--header 'REV-APPNAME: stt_file' \
--header 'REV-APP-ID: ' \
--header 'format: 16k_int16' \
--form 'file=@""'
```
```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: ' \
--header 'REV-APPNAME: stt_file' \
--header 'REV-APP-ID: ' \
--header 'format: wav' \
--form 'file=@""'
```
### `logging`
Possible Values are:
1. `true` - stores audio and keep transcripts in logs.
2. `no_audio` - does not store audios but keep transcripts in logs.
3. `no_transcript` - does not keep transcripts in logs but stores audios.
4. `false` - does not keep neither audios nor transcripts in log.
Default value is `true`
**For Example**:
```javascript logging = true theme={null}
curl --location --request POST 'https://revapi.reverieinc.com/upload' \
--header 'src_lang: hi' \
--header 'domain: bfsi' \
--header 'REV-API-KEY: ' \
--header 'REV-APPNAME: stt_file' \
--header 'REV-APP-ID: ' \
--header 'format: wav' \
--header 'logging: true'
--form 'file=@""'
```
```javascript logging = false theme={null}
curl --location --request POST 'https://revapi.reverieinc.com/upload' \
--header 'src_lang: hi' \
--header 'domain: bfsi' \
--header 'REV-API-KEY: ' \
--header 'REV-APPNAME: stt_file' \
--header 'REV-APP-ID: ' \
--header 'format: wav' \
--header 'logging: false'
--form 'file=@""'
```
### `punctuate`
It will enable punctuation and capitalisation in the transcript. The values it can take are `true` and `false`. Supported languages are: `en`, `hi`. Default value is true
**For Example**:
```javascript punctuate = true theme={null}
curl --location --request POST 'https://revapi.reverieinc.com/upload' \
--header 'src_lang: hi' \
--header 'domain: bfsi' \
--header 'REV-API-KEY: ' \
--header 'REV-APPNAME: stt_file' \
--header 'REV-APP-ID: ' \
--header 'format: wav' \
--header 'punctuate: true'
--form 'file=@""'
```
```javascript punctuate = false theme={null}
curl --location --request POST 'https://revapi.reverieinc.com/upload' \
--header 'src_lang: hi' \
--header 'domain: bfsi' \
--header 'REV-API-KEY: ' \
--header 'REV-APPNAME: stt_file' \
--header 'REV-APP-ID: ' \
--header 'format: wav' \
--header 'punctuate: false'
