Summary

The purpose of this study was to take a critical look at a voice therapy technique known as the yawn-sigh. The voiced sigh as an approach in voice therapy has had increased use in recent years, particularly with problems of vocal hyperfunction. In this study, the physiology of the yawn-sigh was studied with video nasoendoscopy in eight normal subjects; their taped voices were also studied acoustically for possible fundamental frequency and formant changes in producing selected vowels under normal and sigh conditions. Although each subject was given a model by the examiner of a yawn-sigh, one of the eight subjects could not produce a true yawn-sigh. Endoscopic findings for seven of the eight subjects performing the yawn-sigh demonstrated retracted elevation of the tongue, a lower positioning of the larynx, and a widened pharynx. Acoustic analyses for the seven subjects producing the sigh found a marked lowering of the second and third formants. Implications for using the yawn-sigh in voice therapy are given, such as using a modified “silent” yawn-sigh, as an easy method for producing greater vocal tract relaxation.

    This is the first study to our knowledge to examine the effects of LH on cepstral measures and we have showed that low LH had lower CPP in both vowel and connected speech. This finding was unexpected given the use of larynx lowering as a therapeutic intervention in voice therapy78,79 and the use of a lowered larynx position in classical singing training.80 The lower cepstral values in low LH does not necessarily imply an unfavorable larynx position in phonation.

    Therefore, the targeted physiology of the LMM includes that of the yawn-sigh technique used in the treatment of hyperfunctional voice disorders. Laryngeal lowering is accompanied by pharyngeal widening in the yawn-sigh technique,2 and prior studies suggest that both the LMM and the yawn-sigh techniques involve widening and lengthening of multiple areas of the vocal tract from the larynx to the lips. The filtering effects of the vocal tract on the sound source are well established,3 and manipulations to the configuration of any region along the length of the vocal tract will impact resulting resonances.

    They concluded that the lowering of formants is due to the decrease in the laryngeal height and the lengthening of the vocal tract.32 Also, Boone and McFarlane (1997) reported lowered formants in subjects who were treated with the yawn-sigh voice therapy technique.33 Findings of the perceptual-auditory assessment showed positive changes in voice following the therapy.
