Thanks chaley : the google voice to text runs like a dog on my tablet - before too long it wedges and I have to do a cold start. I tried a couple of others - same story. My tablet is a very el-cheapo, made in back of a Guangzhou shop model, and I am not prepared to invest in anything better.
Hence my preference for Windows transcription. I have something half working with an ancient version of Dragon but I've not been able to 'integrate' it with EN as smoothly as I'd like - too much cut and paste. But its low priority, most of my audio notes are not much more than reminders to do X - I usually delete them when I've done X
