Perception of size modulated vowel sequence: Can we normalize the size of continuously changing vocal tract?
2009
Acoustical Science and Technology
Preserved Fulltext
Several studies have demonstrated that the normalization of vocal tract size can be achieved in a bottom-up manner. ...
Changes in vocal tract size vary the formant frequencies, even when the shape of vocal tracts is the same and the spoken vowels are categorized to be the same. ...
According to a study that investigated the relation between the height and the vocal tract length [8] , for which the correlation was high, the vocal tract length of the current speaker was estimated ...

The cry signal results from coordination among several brain regions that control respiration and vocal cord vibration from which the cry sounds are produced. ...
Recall that formants are the harmonic content of a sound produced by mouth shape and vocal cord length. The infant vocal tract is obviously different in size and shape from the adult vocal tract. ...
The infant vocal tract is smaller than the adult vocal track. ...
