$ ml transcribe azspeech [FILENAME] -l <lang> --lang=<lang>

The machine learning hub is useful for demonstrating capability of models as well as providing command line tools.
The command can take an audio wav file, as an optional argument, and transcribe it to the console. For large audio files this can take some time. Currently only wav files are supported through the command line (though the cloud service also supports mp3, ogg, and flac).
