Speech recognition module for e.g. automatic translation, has data acquisition device including differential pressure sensor that is adapted to measure pressure gradient and/or temperature between air exhaled by nose and mouth

摘要

The module (100) has a data acquisition device (12) for acquisition of data of a speaker. An imagery unit (42) is adapted to image a part of a tongue of the speaker and an upper part of a lower tooth of the speaker illuminated by an illumination unit (40). The data acquisition device includes a differential pressure sensor (102) that is adapted to measure a pressure gradient and/or temperature between air exhaled by the nose of the speaker and air exhaled by the mouth of the speaker.
