[Android Central Question]

After I speak into the microphone there is a long long pause before it starts typing the text.... about 30 seconds.

Some speech-to-text algorithms are slower than others - and they're better too. (Of course, Dragon Naturally Speaking is both very fast and very accurate, but you probably couldn't hammer that into a cellphone with a sledgehammer - it's just too large and needs too much CPU. Some day.)

There are different STT or VTT apps in the play store, so try different ones. Usually though, you trade speed for accuracy.
