Better Spectrograms from Children's Speech
A. W. F. Huggins · Journal of Speech Language and Hearing Research · 1980
A major problem in the spectrographic analysis of children's speech is the poor resolution of formants, which is the result of the widely spaced harmonics of the high fundamental frequency. An attempt has been made to bypass this problem by exciting a child's vocal tract with an artificial larynx, using a fundamental frequency appropriate to a man. This method has promise for tracking formants in children's speech.
