Hendo (Didier Demolin, Hubert Ngonga et Alain Soquet)

Data have been recorded with two Hendo speakers at the phonology laboratory of the Université Libre de Bruxelles. Acoustic and aerodynamic parameters have been recorded with the Physiologia workstation (Teston and Galindo [8]) consisting in a computer linked with an acquisition system equipped with different transducers and the signal editing program Phonedit. Oral airflow measurements have been made with a small flexible silicon mask set against the mouth. Nasal airflow has been measured at the end of a nostril via a small olive linked to the acquisition system. Data obtained with an high speed camera for the first speaker are also available here.

Figure 1. Spectrogram, audio-signal and pharyngeal pressure for the word ipaka 'moth' pronounced by the first speaker. 1) indicates the starting point of [i] and the start of pharyngeal cavity expansion, 2) shows when the voicing starts, 3) indicates the end of the voicing and the end of the first phase of pharyngeal pressure raising, 4) shows the release of the bilabial stop closure made for [p].
