Cricotracheal resection can significantly impact the adult female voice. It often lowers the pitch of the speaking voice into the male range and reduces the pitch range of the voice. The change in voice that potentially accompanies this procedure should be discussed with patients in preoperative counseling.

This paper investigates the possible patterns of anticipatory coarticulation in the speech of young children. Speech samples were elicited from three groups of children between 3 and 6 years of age and one comparison group of adults. The utterances were recorded online in a quiet room environment using high quality microphones and direct analog-to-digital conversion to computer disk. Formant frequency measures (F1, F2, and F3) were extracted from a centralized and unstressed vowel (schwa) spoken prior to two different sets of productions. The first set of productions consisted of the target vowel followed by a series of real words containing an initial CV(C) syllable (voiceless obstruent–monophthongal vowel) in a range of phonetic contexts, while the second set consisted of a series of nonword productions with a relatively constrained phonetic context. An analysis of variance was utilized to determine if the formant frequencies varied systematically as a function of age, gender, and phonetic context. Results will also be discussed in association with spectral moment measures extracted from the obstruent segment immediately following the target vowel.
