I have been using the automatic transcript feature for a few days, and it has been amazing. I have a few feature ideas I believe they should add, such as automatically correcting phrases (if you have edited them before), ability to detect different voices, and so much more.
The main idea I would like to see added is the ability to have the Speech to Text feature use .mogrt files (Motion Graphics Template files), this would allow for easier transcription, especially if you have a preset for subtitles, text animations, etc.
Overall, the feature itself has impressed me and many others. If some of the features listed above can be implemented, it would greatly improve the efficiency and ease of access for Transcription. I know there is much more to come with Transcription, and I am very impressed on where the Adobe team has brought this application and many others.
