I’m involved in a few meetings and I’ve been experimenting with transcribing them using Otter on my Android phone (Sorry Apple users).
Just start the App, and it transcribes what it hears through the microphone, and turns it into text on your Android device. The free version allows for up to 40 minutes a recording. Quite clever as it pauses when you are on a phone call and so on.
I also tried it on a radio programme, which worked well. So it looks like you can use Otter on other recordings that you have, such as dictation recorded by someone else.
It does use quite a bit of data, but you can set it to do live transcription over wifi only.
Otter does offer to connect to your calendar and your Google account, but I decided to not let it have access to all about me.
Transcription quality so far is both good and fast so I’ll keep using it and finding out more.
