PHD. 80-037 ABSTRACT In a device for adjusting a movable or electro- acoustic sound transducer an optical duct is connected the sound transducer, which only enables an object, such as for example a display table or a data display unit to be viewed completely in a specific position. This position is unambiguously reproducible and thus also the position of the sound transducer or microphone relative to the mouth of the speaker. The optical duct may be constituted by diaphragms or a tube, as the case may be with intermediate walls, or a phase grating or amplitude grating. In a special case, the object is a display device and the device in accordance with the invention further comprises a device for generating variable data on a display. Since during the speaker identification process the device for the gene- ration of variable data projects consecutive instructions on the display device, the speech recognition process can thus be controlled automatically. The speaker to be identified is then constantly forced to keep his mouth in the correct position relative to the microphone.
