摘要： A voice input system comprising a stationary central unit (1) and a mobile voice interface (2) which is carried around by the user, e.g. in his clothing, is described. The voice interface (2) is used to acoustically record spoken commands which are transmitted to the central unit (1) over a wireless link after being electronically processed. The voice interface contains two or more microphones (3a, 3b, 3c), which cooperate as a microphone array, thereby making possible a directional characteristic during sound recording and also substantial noise suppression. The central unit (1) contains the components for speech recognition, e.g. a processor system, and interfaces (4a. 4b, 4c) via which external appliances are controlled over a wireless link or by cable.

摘要： In a speech device for a hands-free system in a vehicle, at least one microphone is arranged on a guide element encompassing a safety belt. The guide element is fixed to a free end of a holding element, along which there is arranged a first line section of a signal line and/or a supply line of the microphone. One attachable end of the holding element that is opposite the free end, can be fixed in particular to a vehicle seat associated with the safety belt by means of a detachable mechanical connection that comprises at least one electric contact for the microphone.

摘要： Voice command operated systems are being installed in modern motor vehicles with increasing frequency. Such systems should be operable by various vehicle occupants and from various seating positions. A new type of speech recognition system is described, which is good at accomplishing these tasks. Therein, for regulating the speech recognition system, the reception characteristic of a a directionally selective microphone array (12) is controlled by an optimization unit (10). These speech signals are then processed in a speech recognizer (11) at least parallel in time. Then, on the basis of the results provided by the speech recognizer (11), the reception characteristic of the microphone array (12) is so controlled by an optimization unit (10), that the recognition performance of the speech recognizer (11) downstream of the optimization unit (10) is optimized. Herein, the speech recognizer is supplied with the received speech signals from different spatial directions parallel or at least quasi-parallel via the speech channels (14), so that this selects and further processes those speech signals that have the potential for the best possible recognition performance. On the basis of the recognition results, the optimization unit (10) obtains via the speech recognizer the necessary regulatory signals (18), in order to optimize the reception characteristics of the microphone array (12) by means of the optimization unit (10) with regard to the respective direction from which speech signals are received, which have the potential for the best possible recognition performance.

摘要： Parametric loudspeakers that are based on a modulated ultrasound carrier signal produce strong directional patterns. This strong directional patterns require a direct transmission path from the loudspeaker to the audience. Obstacles in this path have a reflecting or absorbing effect. The invention describes a mechanical arrangement of a parametric loudspeaker with a mobile reflector. The arrangement allows tracking of the emitted sound in the direction of a moving audience. The invention provides for advantageous installation possibilities, for example in the rooflining of vehicles or as a mobile system.

摘要： The present invention relates to a method with which speech is captured in a noisy environment with as high a speech quality as possible. To this end, a compact array of, for example, two single microphones is combined to form one system through signal processing methods consisting of adaptive beam formation and spectral subtraction. Through the combination with a spectral subtraction, the reference signal of the beam former is freed from speech signal components to the extent that a reference signal of the interference is formed and the beam former produces high gains.
