From the developer:
RTPITCH is a program for displaying a real time fundamental frequency track for a speech signal. With RTPITCH you can monitor the waveform and pitch of speech sounds being played into the computer's microphone or line input ports. RTPITCH also has an option to display two pitch tracks and switch between them for intonation practice.
