Definitions
- the present invention relates to a hearing device, in particular a hearing aid, with a microphone for receiving ambient sound from the environment of the user. Moreover, the present invention relates to a corresponding method for operating a hearing device.
- WO 03/073790 A1 is a device for detecting and distinguishing speech known. It is inserted in the ear canal and has an external microphone for detecting an ambient sound and an internal microphone for detecting a sound in the ear canal, which includes the own language. This voice commands can be given to the device.
- JP 2003304599A a method of adjusting a hearing aid.
- the amplification factor of the hearing aid is set as a function of an external sound level and as a function of an internal sound level in the ear canal.
- the publication DE 33 25 031 C2 describes an infrared headphone with two microphones. Their signals are supplied to an amplifier in phase opposition, so that the transmission of one's own voice is avoided or suppressed.
- the object of the present invention is thus to improve the automatic control of hearing devices in the presence of the user's own voice.
- the eigenvoice detection device has a level analysis unit, with which the respective level of the two microphone signals is comparable and based on the level comparison, the presence of the user's own voice in the microphone signals can be determined.
- the occlusion effect of the sound in the auditory canal can be exploited in an advantageous manner, after which the own voice in the auditory canal by the structure-borne sound transmission generates a significantly higher sound level than in front of the ear.
- a hearing device can have an AGC device for automatic gain adjustment, which can be temporarily deactivated in the detection of the user's own voice or whose decay time can be temporarily shortened when the user's own voice is detected. This can be avoided in particular disturbances in the conversation with a quiet partner.
- the hearing device may comprise a directional microphone, which is deactivated upon detection of the user's own voice.
- a directional microphone which is deactivated upon detection of the user's own voice.
- an "intelligent directional microphone" can also operate interference-free, even if the hearing aid wearer speaks himself.
- Both the microphone processing device MV including BSS and intelligent directional microphone and the gain unit AGC can be controlled or influenced by the eigenvoice detection PA, ED, SG.

Claims (6)
- Dispositif auditif comprenant- un premier microphone (ME1, ME2) pour capter un son ambiant provenant de l'environnement de l'utilisateur,- un second microphone (MI) pour capter un son de conduit auditif dans le conduit auditif (GG) ou sur la paroi du conduit auditif de l'utilisateur, et- un dispositif de détection de voix propres (PA, ED, SG) pour détecter la propre voix de l'utilisateur à partir des deux signaux de microphone et pour délivrer un signal de commande correspondant,
caractérisé par- un des deux dispositifs suivants :- un dispositif BSS (MV), qui permet d'identifier des sources séparées à partir du signal/des signaux de microphone, et un dispositif de traitement de signal, qui est commandable par le dispositif BSS (MV), la commande du dispositif de traitement de signal par le dispositif BSS (MV) restant temporairement inchangée lorsque la propre voix de l'utilisateur est détectée, ou-un microphone directionnel, qui peut être désactivé en cas de détection de la propre voix de l'utilisateur, et- un dispositif AGC (AGC) de réglage automatique de gain, qui peut être temporairement désactivé en cas de détection de la propre voix de l'utilisateur, ou dont la durée d'évanouissement peut être temporairement écourtée en cas de détection de la propre voix de l'utilisateur. - Dispositif auditif selon la revendication 1, dans lequel le dispositif de détection de voix propres (PA, ED, SG) comprend un dispositif d'analyse de niveau (PA), qui permet de comparer le niveau respectif des deux signaux de microphone et de déterminer à l'aide de la comparaison de niveau, la présence de la propre voix de l'utilisateur dans les signaux de microphone.
- Dispositif auditif selon la revendication 2, dans lequel seules les fréquences inférieures à 1 kHz sont prises en compte par l'unité d'analyse de niveau (PA).
- Procédé pour faire fonctionner un dispositif auditif par- captage d'un premier signal acoustique provenant de l'environnement d'un utilisateur,- captage d'un second signal acoustique provenant du conduit auditif (GG) de l'utilisateur,- détection de la propre voix de l'utilisateur par analyse (PA, ED) des deux signaux acoustiques, et- commande du dispositif auditif en fonction de la présence de la propre voix de l'utilisateur,
caractérisé en ce que- soit- une commande d'adaptation BSS du dispositif auditif est gelée lorsque la propre voix de l'utilisateur est détectée, ou-un microphone directionnel du dispositif auditif est désactivé lorsque la propre voix de l'utilisateur est détectée, et- un dispositif AGC (AGC) de réglage automatique de gain, qui peut être temporairement désactivé en cas de détection de la propre voix de l'utilisateur, ou dont la durée d'évanouissement peut être temporairement écourtée en cas de détection de la propre voix de l'utilisateur. - Procédé selon la revendication 4, dans lequel l'analyse (PA, ED) des deux signaux acoustiques comporte une comparaison de niveau.
- Procédé selon la revendication 5, dans lequel seules les fréquences inférieures à 1 kHz sont prises en compte dans l'analyse (PA, ED).
