  • Abstract
    An important aid in the analysis and display of speech is the sound spectrogram, which represents a time-frequency¿intensity display of the short-time spectrum.1-3 With many modern speech facilities centering around small or medium-size computers, it is often useful to generate spectrograms digitally, online. The fast Fourier transform algorithm provides a mechanism for implementing this efficiently.
