Record a user's expressed opinion about an owned transcription. Call it once, only after the user explicitly gives an opinion of a result: rating good or bad as they said it, and comment a non-empty quotation of their own words. Never supply a rating or ask for one. Optional issues classify pitch, rhythm, readability, parts or speed problems. revision is the one they judged (default: the current saved version). Feedback does not authorize sharing the recording; the user's panel buttons handle sharing.
