Regenerating the spectral shapes of [s] and ['ИНТЕГ'] from a limited set of articulatory parameters [Text] / Noel Nguyen, Philip Hoole, Alain Marchal // J. Acoust. Soc. Amer. - 1994. - Vol. 96, N 1. - P33-39 . - ISSN 0001-4966
Перевод заглавия: Восстановление спектральных форм [s] и ['ИНТЕГ'] при ограниченном наборе параметров артикуляции
Аннотация: This work was aimed at exploring articulatory-acoustic relationships in the production of French fricatives. More precisely, an attempt was made to find out whether the spectral shapes of [s] and ['ИНТЕГ'] can be regenerated from the x and y coordinates of three electromagnetic transducers affixed to the tongue in the midsagittal plane. The corpus was composed of the two fricatives /s/ and /'ИНТЕГ'/ combined with the vowels /а/ and /i/ in sequences of the type /Vs'ИНТЕГ'V/ and /V'ИНТЕГ'sV/, and was read by one male native speaker of French. The spectrum regeneration was based on a statistical procedure which consisted of estimating the factors explaining the main part of the acoustic variance from the position of the transducers, by means of multiple linear regression. The articulatory-acoustic correlations were high and allowed us to regenerate the fricative spectra with a good accuracy. The way in which the acoustic parameters varied as a function of the articulatory ones in the statistical model was in good agreement with data reported in previous works. The results support the idea that the tongue has relatively few degrees of freedom in the production of [s] and ['ИНТЕГ'].

Nguyen, Noel.
Assessment of an electromagnetometric system for the investigation of articulatory movements in speech production [Text] / Noel Nguyen, Alain Marchal // J. Acoust Soc. Amer. - 1993. - Vol. 94, N 2. - P1152-1155 . - ISSN 0001-4966
Перевод заглавия: Оценка электромагнитометрической системы для изучения артикуляционных движений при речепродукции
Аннотация: Electromagnetometry can be used to track articulatory movements during speech production by means of small electromagnetic receivers attached to the articulators. This study was aimed at determining the measurement accuracy of the Movetrack system marketed by Botronic (Sweden). The average difference between a position transduced by Movetrack and the actual position, obtained from a precision mechanical device, was less than 0.4 mm, when the receiver was placed in the midsagittal plane and parallel to the transmitters at a distance of about 25 cm from each transmitter. Higher deviations were observed when the receiver was tilted with respect to the transmitters. Thus the device appears to be capable of delivering accurate measures of position for rigid anatomical structures like the jaw, which are not likely to produce tilt.
