Method and apparatus for separating speech data from background data in audio communication

1. A method for separating speech data from background data in an audio communication, comprising:

applying a spectral speech model to the audio communication for separating the speech data from the background data of the audio communication; and

updating the spectral speech model as a function of the speech data and the background data during the audio communication.

2. The method according to claim 1 , wherein the updated spectral speech model is applied to the audio communication.

3. The method according to claim 1 , wherein a spectral speech model associated with a caller of the audio communication is applied as a function of a calling frequency and a calling duration of the caller.

4. The method according to claim 1 , wherein a spectral speech model which is not associated with a caller of the audio communication is applied as a function of a calling frequency and a calling duration of the caller.

5. The method according to claim 1 , further comprising:

storing the updated spectral speech model after the audio communication for using in a next audio communication.

6. The method according to claim 4 , further comprising:

changing the spectral speech model to be associated with the caller of the audio communication after the audio communication as a function of the calling frequency and the calling duration of the caller.

7. Computer program product which is stored on a non-transitory computer readable medium and comprises program code instructions executable by a processor for implementing the steps of a method according to claim 1 .

8. An apparatus for separating speech data from background data in an audio communication, comprising:

an applying unit for applying a spectral speech model to the audio communication for separating the speech data from the background data of the audio communication; and

an updating unit for updating the spectral speech model as a function of the speech data and the background data during the audio communication.

9. The apparatus according to claim 8 , wherein the applying unit is configured to apply the updated spectral speech model to the audio communication.

10. The apparatus according to claim 8 , wherein the applying unit is configured to apply a spectral speech model which is associated with a caller of the audio communication as a function of a calling frequency and a calling duration of the caller.

11. The apparatus according to claim 8 , wherein the applying unit is configured to apply a spectral speech model which is not associated with a caller of the audio communication as a function of a calling frequency and a calling duration of the caller.

12. The apparatus according to claim 8 , further comprising:

a storing unit configured to store the updated spectral speech model after the audio communication for using in a next audio communication.

13. The apparatus according to claim 11 , further comprising:

a changing unit configured to change the spectral speech model to be associated with the caller of the audio communication after the audio communication as a function of the calling frequency and the calling duration of the caller.
