Submitting a Sample File for Text Transcription

To download the sample audio file that is used in this chapter, right-click here and select Save link as from the pop-up menu that displays.

The following command calls the V‑Cloud API, specifies the address of the callback server, specifies that you want text format output, and identifies the audio file that you want to transcribe:

curl -F callback=http://www.example.com:5555 \
     -F token=123e4567e89b12d3a456426655440000 \
     -F output=text -F "file=@sample7.wav;type=audio/x-wav" \

This sample command sends a text transcript of the audio file sample7.wav to the callback server. The text that was transcribed via the curl command that was shown previously is the following:
