microphone array, 3D acoustic field distribution, adaptive beam-forming, oral, oronasal and nasal articulationsAbstract
This article presents a 16-channel microphone-array recorder/processor that allows for a simultaneous and non-invasive detection of oral, oronasal and nasal segments in speech. Such devices and methods have not been used in the research on the articulation of sounds in the world’s languages. In this paper analysis of Polish nasal vowel was presented. Adaptive beamforming method used for rendering three-dimensional acoustic fields of the recorded audio data has been shown.
