This speech processing exercise enables the user to time-reverse and/or spectrum invert a user-specified speech signal using simple signal processing techniques. The processed speech signal can be plotted as a sound spectrogram or as an acoustic waveform or as a frame-based plot of short-time log energy and zero crossing rate. The processed signal can also be played out as an ordinary audio file.
