Problems solved by technology

[0007] According to the invention, the first-mentioned technical problem is solved by a method for individual signal processing of audio signals of a hearing aid, in which a first image record is generated by an auxiliary device for the audio signal in a recognition phase, from which a conclusion is drawn the presence of a preferred interlocutor, and then analyze the audio signal and / or the first audio sequence of the auxiliary audio signal of the auxiliary device with respect to characteristic speaker discrimination parameters, and identify the speaker identified in the first audio sequence Parameters are stored in the database

Embodiment Construction

[0039] figure 1 The identification phase 1 of the method for individual signal processing in a hearing aid 2 is schematically shown in a block diagram. The goal of the recognition phase 1 is to be able to determine specific acoustic parameters for a specific person from the closer surroundings of the user of the hearing aid 2 in a manner yet to be described, from which acoustic parameters can be identified in the input signal of the hearing aid 2 as the The signal components of the speech contributions of the persons involved are used in order to be able to emphasize the speech contributions of the persons involved in a targeted manner for the user of the hearing aid 2 relative to the noise background and relative to other speech contributions of other speakers. This is done in particular under the assumption that due to the personal relationship between the user of the hearing aid 2 and the speakers, the voice contributions of these persons are of particular importance to the...

Abstract

The invention relates to a method for individualized signal processing of an audio signal (12) of a hearing device. In a recognition phase (1), an auxiliary device (4) generates a first image capture(8). A conclusion is reached based on the first image capture regarding the presence of a preferred conversation partner (10), and thereupon a first audio sequence (14) of the audio signal and / or of an auxiliary audio signal of the auxiliary device (4) is analyzed for characteristic speaker identification parameters (30). The speaker identification parameters ascertained from the first audio sequence (14) are stored in a database (31). In an application phase (40), the audio signal is analyzed with respect to the stored speaker identification parameters (30), and is thereby evaluated with respect to a presence of the preferred conversation partner. When the preferred conversation partner is detected as being present, the partner's signal contributions in the audio signal are amplified.

Description

technical field [0001] The invention relates to a method for individual signal processing of audio signals of a hearing aid. The invention also relates to a system with a hearing aid for carrying out such a method. Background technique [0002] In the field of audio signal processing of speech signals, ie audio signals whose signal contribution is largely derived from the speech contribution, the following problems often arise: the speech contribution is to be increased in the recorded audio signal relative to the noise background, That is, the voice component is amplified relative to the remaining signal components. This type of amplification can be achieved by complex, non-real-time signal processing algorithms for audio signals in which the reproduction is set in a significantly time-shifted manner relative to the recording, i.e. for example in soundtracks used in film production In the case of recording, this is much more difficult for the case where signal processing ...
