When Premier Beta transcripts the audio, it often makes mistakes in the transcription, as most transcribers do. It is important to be able to edit these errors and have the software accept the edit and playback in the voice of the speaker. That would be enough for now. But, to make this software most useful and powerful, users should at some point be able to copy and paste text to the transcript and have the software accept that and play that back in the voice of the speaker. In my case, I am most often only editing audio/video in a single-speaker voice. With these changes/updates, Premier Pro would be most useful and powerful. I really what you have done so far.
