Spectrograms are used in speech therapy to help with pronunciation. I remember using one such program to correct my own speech, at elementary school in the 90s. It was even a game: I moved a cursor through a maze and it would only move in the correct direction when my sound I made was correct. The game had a spectrogram for additional visual feedback -- my speech therapist could point to an area on it and tell me that I was placing my tongue incorrectly or whatever. Its a really cool example of the power of biofeedback.
