1. A method comprising:
obtaining a microphone signal captured by a first device participating in a call with a second device;
detecting the presence of the designated sound using the microphone signal or a video signal captured by the first device;
in an instance when the presence of the designated sound is not detected, performing first enhancement processing of the microphone signal to obtain a first enhanced microphone signal, the first enhancement processing being adapted to suppress a designated sound and one or more other sounds;
in an instance when the presence of the designated sound is detected, performing second enhancement processing of the microphone signal to obtain a second enhanced microphone signal, the second enhancement processing being adapted to suppress the one or more other sounds and retain the designated sound; and
sending a playback signal to the second device that is participating in the call with the first device, the playback signal including the first enhanced microphone signal when the presence of the designated sound is not detected or the second enhanced microphone signal when the presence of the designated sound is not detected.
