Abstract
In order to make the operation, control and/or program selection of a hearing aid easier and in order to make manual operations and actuation means superfluous, the operation (switching on/off, setting softer/louder, selection of a program matched to an auditory/ambient situation) or the control of a part that influences the transmission characteristic of the amplifier ensues in the hearing aid by recognizing and evaluating a code word spoken by the hearing aid user.
Claims14
A hearing aid comprising:
- a microphone for receiving incoming audio signals and for generating electrical signals corresponding to said incoming audio signals;
- means for processing said electrical signals to produce processed electrical signals, said means for processing including an amplifier with an adjustable gain for setting a volume and having settable amplifier transmission characteristics;
- an electro-acoustic transducer, supplied with said processed electrical signals, for converting said processed electrical signals into acoustic signals and for emitting said acoustic signals to a hearing-impaired person;
- on-off means for setting and deactivating at least one of said microphone, said means for processing and said electro-acoustic transducer;
- and
- a voice control circuit having means for receiving a spoken command, means for recognizing said spoken command as being spoken by said hearing-impaired person, processor means for evaluating said spoken command and for converting said spoken command into an electrical control signal for setting at least one of the gain of said amplifier, the transmission characteristics of said amplifier and said on-off means.
