Abstract

In the method according to the invention the communication device has a microphone and a signal path leading from the microphone to a speaker, where the signal path comprises a programmable signal processing unit. According to the method the user is given control in a training session over one or more signal processing parameters within the signal processing unit. In the training session the user listens to the sound of his or her own voice transmitted through the communication device, and adjusts the one or more signal processing parameters until he or she is satisfied with the sound quality of his/her own voice. The values of the signal processing parameters chosen by the user during the training session are stored in a storing means within the device, and the programmable signal processing automatically uses the stored parameter when detection means within the unit detects the users own voice.

Claims

1. Method of programming a communication device having a microphone and a signal path leading from the microphone to a speaker, where the signal path comprises a programmable signal processing unit whereby the user in a training session is given control over one or more signal processing parameters within the signal processing unit, and whereby the user in the training session during listening to the sound of his or her own voice transmitted through the communication device, adjusts the one or more signal processing parameters until he or she is satisfied with the sound quality of his/her own voice, and where the values of the signal processing parameters chosen by the user during the training session are stored in a storing means within the device, and whereby the programmable signal processing automatically uses the stored parameter when detection mean within the unit detects the users own voice.

2. Method as claimed in claim 1, wherein the signal processing parameters, which are controlled by the user during the training session comprises one or more of the following:

overall level, pitch, spectral shape, spectral comparison of auto-correlation and auto-correlation of predictor coefficients, spectral coefficients, prosodic features or modulation metrics.

3. Method as claimed in claim 1, wherein the detection means comprises a further input channel, which is connected to detection means in order to detect when the users own voice is active.

4. Method as claimed in claim 1, wherein the detection of the users own voice is accomplished by use of a means for generating and storing a first set of descriptive parameters of the signal from the microphone during user vocalization and means for generating a further set of descriptive parameters during normal use of the communication device and use of a means for comparing the further set of descriptive parameters with the first set of stored descriptive parameters in order to decide whether the signal from the microphone comprises sounds originating from the users voice.

5. Method as claimed in claim 4, wherein the descriptive parameters comprises the energy content of low and high frequency bands.

6. Communication and listening device for use in the method according to claim 1 with a microphone and a signal path leading from the microphone to a speaker, where the signal path comprises a programmable signal processing unit whereby the communication device further comprises:

detection means associated with the signal path for detecting when the signal in the signal path contains sounds originating from the users voice;

means for storing at least one user chosen parameter set of the program for controlling the processing unit,

means for applying the user chosen parameter set for the program for controlling the signal processing unit, when sounds originating from the users voice are detected.

7. Communication and listening device as claimed in claim 6, wherein the detection means for detecting when the signal in the signal path contains signals originating from the users voice comprises:

means for generating and storing a first set of descriptive parameters of the signal from the microphone during user vocalization,

means for generating a further set of descriptive parameters during normal use of the communication device,

means for comparing the further set of descriptive parameters with the first set of stored descriptive parameters in order to decide whether the signal from the microphone comprises sounds originating from the users voice.

8. Communication and listening device as claimed in claim 6, wherein the descriptive parameters comprises one or more of the following:

overall level, pitch, spectral shape, spectral comparison of auto-correlation and auto-correlation of predictor coefficients, prosodic features, modulation metrics or activity on a further input channel caused by vocal activity.
