Acceleration sensor measurements of subglottal sound pressure for modal and breathy phonation quality
نویسندگان
چکیده
We present a non-invasive attempt to indirectly measure the subglottal sound pressure. This quantity opens an additional acoustical path to observe the voiced sound source. The subglottal sound pressure contours of two phonation qualities, the modal phonation quality and the breathy phonation quality, are compared. The electroglottographic signal was recorded simultaneously as a well known reference basis for physiological details of voice production.

Analysis of breathy, modal and pressed phonation based on low frequency spectral density
Breathy phonation has a high open quotient compared to modal phonation which results in greater influence of the subglottal cavity on the estimated short-time spectrum. This is reflected as an increase in spectral density at frequencies below the first resonance of the vocal tract around the glottal formant. On the contrary, pressed phonation has lesser influence of the subglottal cavity, and h...
متن کاملComparison of manual and automated estimates of subglottal resonances
This study compares manual measurements of the first two subglottal resonances to the results of an automated measurement procedure for the same quantities. We also briefly sketch the sensor prototype that is used for the measurements. The subglottal resonances are presented in the space spanned by the vowels’ first two formants. A three axis acceleration sensor is gently pressed at the neck of...
متن کاملAcoustic and Electroglottographic Study of Breathy and Modal Vowels as Produced by Heritage and Native Gujarati Speakers
While all languages of the world use modal phonation, many also rely on other phonation types such as breathy or creaky voice. For example, Gujarati, an Indo-Aryan language, makes a distinction between breathy and modal phonation among consonants and vowels: /bɦaɾ/ ‘burden’, /baɾ/ ‘twelve’, and /ba̤ɾ/ ‘outside’ [1, 2]. This study, which is a replication and an extension of Khan [3], aims to dete...
متن کاملA comparison of subglottal and intraoral pressure measurements during phonation.
Intraoral pressure and subglottal pressure, derived from tracheal puncture, were recorded with the electroglottographic signal for one normal speaking male during phonation. The mean subglottal pressure for vowels was also estimated by interpolating the intraoral pressure from surrounding /p/occlusions. The pressure measurements were highly correlated (r = 0.98) and there were small pressure va...
