/v1alpha/applications/{app_id} needs more clear documentation for text / speech upload
For example, if application wants to send speech data it needs only to do HTTP PUT to speech_upload_url. Example CURL command: curl -H "x-ms-blob-type: BlockBlob" -X PUT --data-binary "@audio.wav" "<speech_upload_url>"
What if the WAV is a local file on the smartphone?
