Passing Parameters

Voci’s transcription service is highly configurable, enabling you to control details of how each audio file or stream is transcribed. In most cases, V‑Blaze's default behavior will provide the best results. The parameters described in V‑Blaze Transcription Parameters enable you to modify default behavior when needed.

Parameter specifications must appear in the post before the audio file(s) to be transcribed. Providing a parameter setting (such as "emotion=true") after a file specification results in an error:

curl -i -F file=@sample1.wav \
        -F emotion=true \
        http://vblaze_name:17171/transcribe
HTTP/1.1 400 Bad Request
    Content-Type: text/plain
    Content-Length: 23
    Last field must be file

Make sure to always provide parameter settings before the file specification, as shown here:

curl -i -F emotion=true \
        -F file=@sample1.wav \
