Web1 The simplest way is to use a fixed-length FFT instead of an STFT (spectrogram). That will eliminate your variable-length problem. Why don't you just apply a recurrent neural network? Do you just need a worked example? If so, are you flexible about which software to use? – Emre Jan 29, 2016 at 20:29 1 エクセル 両面印刷 macWebThis paper develops criteria for the segmentation of vowels on duplex oscillograms. Previous vowel duration studies have primarily used sound spectrograms. The use of duplex oscillograms, rather than sound spectrograms, permits faster production (real time) at less expense (adding machine paper may be used).
