摘要

Quantitative analysis of lateral sigmatism is a challenge for contemporary speech therapy. In the paper a prototype of an acquisition device for voice and lateral air flow registration is described. The proposed acoustic mask enables for registration of signal from 7 microphones placed in different positions in the area around the mouth. Tests considering air flows directed centrally and laterally have been conducted. Artificially generated air streams and lateral speech utterances have been considered. Energy distribution analysis has been performed to distinguish the direction of the interferences. The results confirm that the acoustic mask may be used in diagnosis and speech therapy of lateral sigmatism.
