On the whole it works quite well which is a miracle in and of itself! At times though the words I said quite clearly and close to the mike (and w zero background noise) aren't transcribed. I'm expecting word recognition delays and misunderstood words, so I repeat the phrase louder. Now, annoyingly, both the phrase and the repetition are transcribed. The clinch is: After a while I figured out that saying anything louder (like "full stop") will bring up the missing phrase, so it was recognized and understood all along, just not displayed. Waiting alone doesn't work. I have to say something really loud.
While we're at it: I wish the microphone wouldn't switch itself off after, what is it? 30sec? Or at least that it would indicate this w a beep, like it does, when I bring it up.
