摘要：

Existing speech spectrograms-the wide-band spectrogram and the narrow-band spectrogram-are either deficient in time or frequency resolution. Here we present a method to combine the two spectrograms by evaluating the geometric mean of the corresponding short-time Fourier transform magnitudes. The combined spectrogram preserves the desirable visual features of the originals.
