Here at CSLU we are assembling a corpus of common English words in order to display their waveforms and spectrograms. One such word is presented on this page. Click here to see what other words are currently available.
We can combine the display of a waveform and a spectrogram for the same utterance along with a ruler which gives a measure of elapsed time. Figure 1 below is one such display, for the word "compute." Notice the correspondences between the two displays.
