Subtitling: transcription add-ins?

Could you have a could you have a speech-to-text transcription add-in for this to allow for the creation of the source text e.g. like Adobe Premiere Pro introduced this week?

That way we would have a complete tool and wouldn't have to resort to another software to create the subtitles and then go to Trados Studio to translate them, it would be wonderful to do all the process using just Trados Studio.
