Whether your partner is accusing you of snoring or if you are convinced that you might talk in your sleep, the argument can be settled by using Sleep Talk Recorder, a free (for a limited time) sound-activated iPhone and Android app that records audio specifically for this purpose.
It’s all a bit of fun, as you can see from the sound clips that app makers MadInSweden encourage users to share. In fact, they’re making a documentary on the subject of sleep talkers based on interviewers with app users, including one elderly man who discovered that he sang in Yiddish in his sleep!
I gave it a try but it turns out I’m pretty mundane – not even a snore.
