ABSTRACT:
The invention relates to a communication terminal provided which selectively distorts an acoustic signal inputted by the user to the communication terminal during a call to another user of a communication terminal. The invention enables a user of a first communication terminal to selectively distort an acoustic signal inputted into the first communication terminal during a call with a user of a second communication terminal, where the method includes that the user of the first communication terminal inputs an acoustic signal. A processor in the first communication terminal distorts the signal according to a selection in the first communication terminal, where the selection is user defined or selected. The processor transfers the distorted signal and transmits the signal via a communication network to the second communication terminal, where a processor of the second communication terminal receives the distorted signal and uses the distorted signal as output acoustic signal in the second communication terminal to the user of the second communication terminal.
