Abstract
In a device for adjusting a movable electro-acoustic sound transducer, an optical duct is connected to the sound transducer which only allows an object, such as a display table or a data display unit, to be viewed completely in one specific position. This position is unambiguously reproducible and so is the position of the sound transducer or microphone relative to the mouth of the speaker. The optical duct may comprise diaphragms or a tube, possibly with intermediate walls, or a phase amplitude grating. The object may be a display unit and the device further comprises a device for generating variable data on the display. If used for speaker identification, the variable data generator projects consecutive instructions on the display so that, the speech recognition process is controlled automatically. The speaker to be identified is then required to keep his mouth in the correct position relative to the microphone.
