Abstract
A method of adjusting received speech volume in a handset is disclosed. The method comprises initialize a variable BFI_FACTOR as 1. Using the BFI (bad frame indicator) to determine whether a current received speech frame is erroneous or not. If the current received speech frame is not erroneous, determining if the BFI_FACTOR is less than one and if so incrementing the BFI_FACTOR. If the BFI indicates an erroneous frame, determining if the BFI_FACTOR is above a minimum value and if so decrementing the BFI_FACTOR. Finally, the current speech signal is multiplied by the BFI_FACTOR and played to the user.
Claims7
A method of adjusting received speech volume in a handset comprising:
- (a) initialize a variable BFI_FACTOR as 1;
- (b) using a BFI (bad frame indicator) to determine whether a current received speech frame is erroneous or not;
- (c) if the BFI equals one, going to step (h);
- otherwise, going to step (d);
- (d) determine whether the BFI_FACTOR is less than one, and if so, going to step (e), otherwise, going to step (f);
- (e) adding an increment factor to the BFI_FACTOR;
- (f) multiplying a current speech signal by the BFI_FACTOR;
- (g) playing the received speech data and going to step (b);
- (h) determining whether the BFI_FACTOR greater than a minimum value, and if true, going to step (i), otherwise going to step (j);
- (i) subtracting a decrement factor from BFI_FACTOR;
- and
- (j) playing the received speech data and going back to step (b).
