V‑Cloud transcription parameters, often referred to as stream tags, enable you to customize how each audio file will transcribe. Transcription parameters are key-value pairs passed in the body of the request. The syntax of a parameter is name=value, as shown in the following example:

curl -F file=@sample1.wav \
     -F token=your-token-here \
     -F emotion=true \
