Abstract: A virtual assistant is provided which outputs audible information to a user of a data terminal. A method is also provided for presenting audible information of a virtual assistant to the user of a data terminal. At least two electroacoustic converters are driven such that the virtual assistant can be spatially positioned by a data terminal use to achieve acoustic separation between the electroacoustic converters and an additional sound source.

Abstract: A method and device are provided for the interference elimination of a redundant acoustic input signal of an acoustic reproducing device, such as a mobile phone or a hearing aid, according to which the interference is concentrated in a partial frequency range of a total frequency range of the input signal. The present invention seeks to improve the sound quality of an acoustic output signal produced.

Abstract: The aim of the invention is to control the bass reproduction of audio signals in electroacoustic transducers based on the psychoacoustic principle denoted by the term “virtual pitch” or “residual hearing (hearing of missing fundamental)”, in such a way that the perception of the virtual bass reproduction of the audio signals is improved in relation to prior art. To this end, the reproduction of the low pitched frequencies or basses released in the electroacoustic transducer is controlled by the amplification of the harmonic waves already contained in the audio signals, in the form of a simulation, in such a way that the listener experiences or perceives an improved bass reproduction.

Abstract: A method is provided for expanding the bandwidth of a narrow band filtered speech signal, particularly a speech signal transmitted by a telecommunications device, in a simple and cross-effective manner without losses in quality, wherein the narrow band filtered speech signal is estimated in relation to frequency components above a cut-off frequency via independent methods either in the time domain or in the frequency domain and expanded on the basis of the respective estimation.

Abstract: At least one flexible element (1, 32, 33a, 33b) which converts a mechanical pressure change into an electrical voltage variation (microphone) or an electrical voltage variation into a mechanical pressure change (loudspeaker) is connected to the fabric of items of clothing (30, 300). Furthermore, the flexible element (1, 32, 33a, 33b) is connected, by means of a wire or without, to an audio signal source (31) and/or an audio signal sink (31) which are associated with the item of clothing (30, 300) or integrated into the same (30, 300).

Abstract: A mobile communications terminal is provided having a first loudspeaker for emitting sound signals in a normal mode of the communications terminal, a second loudspeaker for emitting sound signals in a hands-free mode of the communications terminal, an antenna and a signal processing device for processing signals which have been received by the antenna and for supplying processed signals to the first loudspeaker and to the second loudspeaker depending on whether the communications terminal is in the normal mode or in the hands-free mode, wherein better high-frequency reproduction in a hands-free mode is achieved in that, in the hands-free mode, the signal processing device is designed to supply processed signals at a frequency of more than 1 kHz to the first loudspeaker and the first loudspeaker is designed to reproduce sound signals at a frequency of more than 1 kHz.

Abstract: A mobile communications terminal is provided which is designed to transmit speech signals and to receive and reproduce speech signals, and which has a speech-reproduction device, wherein improved speech quality is achieved in that the speech-reproduction device has a sound transducer, which is disposed inside a housing of the mobile communications terminal, and at least one sound transmission opening provided in the housing, which forwards the sound generated by the sound transducer to the outside of the mobile communications terminal.

Abstract: The aim of the invention is to control initiation of actions in a user-independent manner and by means of voice and users pertaining to a limited circle of users of an appliance, whereby said actions can be carried out in the appliance. The voice is detected on the basis of a speaker-dependent voice detection system in a user-independent manner and without user identification. The reference voice patterns of all users pertaining to a voice detection system are allocated to detection voice expressions, e.g. the words of a vocabulary, of the users pertaining to the circle of users, whereby said patterns are required for detection.
