Abstract
The speech spectrogram is a two-dimensional time-frequency display of a one-dimensional signal. The wideband spectrogram and the narrowband spectrogram are deficient either in frequency or in time resolution. The authors present a method for combining the two spectrograms by evaluating the geometric mean of their corresponding pixel values. The combined spectrogram appears to preserve the visual features associated with high resolution in both frequency and time
