Definitions

  • the invention relates to a binaural method and a binaural arrangement for voice control of hearing aids with voice commands with a first and a second hearing aid.
  • hearing aids also include tinnitus markers and anti-stuttering aids.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually integrated in a signal processing unit.
  • FIG. 1 illustrated by the example of a behind-the-ear hearing aid 1.
  • In a hearing aid housing 2 for carrying behind the ear usually two microphones 3 are incorporated for receiving the sound from the environment. Above the microphones 3 microphone openings 7 are formed in the hearing aid housing 2.
  • a signal processing unit 4 which is also integrated in the hearing aid housing 2, processes the microphone signals and amplifies them.
  • the output signal of the signal processing unit 4 is transmitted to a loudspeaker or receiver 5, which outputs an acoustic signal.
  • the sound is optionally transmitted via a sound tube, not shown, which is fixed with an earmold in the ear canal, to the eardrum of the hearing aid wearer.
  • the power supply of the hearing device 1 and in particular that of the signal processing unit 4 is effected by a battery 6 likewise integrated into the hearing device housing 2.
  • the invention claims a method for voice control of hearing aids with voice commands with a first hearing aid and a second hearing aid in a binaural arrangement.
  • a first voice recognition method of the first hearing device for recognizing the voice commands uses information data a second speech recognition method of the second hearing aid.
  • the advantage of this is that the rate of misrecognized voice commands ("false alarms") is reduced while maintaining the hit rate.
  • the information data may comprise a second voice command recognized by the second voice recognition method.
  • Voice control becomes more error-free and robust.
  • a voice command can only be used for voice control if the second voice command matches a first voice command recognized by the first voice recognition method.
  • the information data may include acoustic parameters, voice activity detection results, and / or probabilities of recognized voice commands.
  • the second speech recognition method may be the same as the first speech recognition method.
  • the information data from the first hearing aid can be transmitted wirelessly to the second hearing aid.
  • the invention also claims a binaural arrangement with a first and a second hearing device for voice control of hearing aids by voice commands.
  • the arrangement comprises a first voice recognition module in the first hearing aid and a second voice recognition module in the second hearing aid, which uses information data of the first voice recognition module to recognize the voice commands.
  • the information data may comprise a first voice command recognized by the first voice recognition module.
  • a voice command can only be used for voice control if the first voice command matches a second voice command recognized by the second voice recognition module.
  • the information data of the arrangement may include acoustic parameters, results of voice activity detection, and / or probabilities of recognized voice commands.
  • the arrangement may comprise a first speech recognition algorithm in the first speech recognition module and a second speech recognition algorithm in the second speech recognition module.
  • the first speech recognition algorithm can be equal to the second speech recognition algorithm.
  • the arrangement may comprise a first radio module in the first hearing device and a second radio module in the second hearing device, wherein the first radio module transmits the information data to the second radio module.
  • FIG. 2 shows a flowchart of a method for voice control of a hearing aid 10, 20 with voice commands.
  • a first and a second hearing device 10, 20 are used in a binaural arrangement for this purpose.
  • the first hearing aid 10 supplies the left ear and the second hearing aid 20 the right ear of a hearing aid wearer.
  • a first speech recognition method is implemented in the first hearing device 10 and a second speech recognition method is implemented in the second hearing device 20.
  • the speech recognition methods can be the same. They have common or hearing aid-specific speech recognition algorithms.
  • the number of voice commands to be recognized is limited and usually includes five to a maximum of twenty commands.
  • the hearing aids 10, 20 wait for the delivery of a voice command by the hearing aid wearer.
  • the acoustic input signals are continuously analyzed.
  • the first hearing device 10 recognizes a first voice command and sends it in the following step 102 to the second hearing aid by means of wireless communication.
  • the second hearing aid 20 receives the first voice command.
  • the second hearing device 20 has recognized a second voice command simultaneously to step 101 in step 104.
  • step 105 the second hearing device 20 compares the self-determined second voice command with the first voice command received by the first hearing aid 10. If the two voice commands match, the first and second voice commands are executed in step 106. Subsequently, the process returns to step 100. If the two voice commands do not match, the procedure immediately proceeds to step 100.
  • the method can, of course, also run simultaneously in the reverse direction, ie the second hearing device 20 transmits its recognized second voice command to the first hearing device 10.
  • the first hearing device executes the voice command, if the self-determined first voice command matches the received second voice command.
  • FIG. 3 shows a block diagram of a binaural arrangement according to the invention with a first hearing aid 10 and a second hearing aid 20, which can exchange data via a radio communication 30.
  • the first hearing device 10 comprises a first signal processing unit 14, which processes and amplifies acoustic signals recorded by a first microphone 13 in the form of electrical signals and forwards them to a first receiver 15 for acoustic emission.
  • the microphone signal of the first microphone 13 is analyzed for the presence of previously known voice commands.
  • the speech recognition takes place with the aid of a first speech recognition algorithm 12 in the first speech recognition module 11.
  • the first hearing aid 10 can wirelessly exchange data with the second hearing aid 20 using a first radio module 16.
  • the second hearing device 20 comprises a second signal processing unit 24, which processes and amplifies acoustic signals recorded by a second microphone 23 in the form of electrical signals and forwards them to a second listener 25 for acoustic emission.
  • a second voice recognition module 21 the microphone signal of the second microphone 23 is analyzed for the presence of previously known voice commands.
  • the speech recognition is carried out by means of a second speech recognition algorithm 22 in the second speech recognition module 21.
  • the second hearing aid 20 with the first hearing aid 10 wirelessly exchange data.
  • the first hearing aid 10 sends the recognized first voice command to the second hearing aid 20 using the first radio module, which receives this first voice command by means of the second radio module 26.
  • the second voice recognition module 21 in turn has itself recognized a second voice command.
  • the second voice recognition module 21 now compares the first and second voice commands and controls the second signal processing unit 24 with the second voice command only when the first and second voice commands match.
  • the binaural arrangement works analogously in the opposite direction.
  • the first voice recognition module 11 compares the first and second voice commands and controls the first signal processing unit 14 with the first voice command only when the first and second voice commands match.
