A method of transmitting voice information and an electronic communications device for transmission of voice information |
摘要 |
A method of transmitting voice information from an electronic communications device (1) comprises the steps of receiving the voice information from the environment of the device together with a first background sound, generating a sound signal having a first signal part representing the voice information and a second signal part representing the first background sound, reducing the signal part representing the first background sound, and transmitting the sound signal through a communications channel to which the device is connected. The method further comprises the step of adding to the sound signal an additional signal representing a second background sound. In this way background noise can be removed, while a natural and comfortable conversation can be maintained without revealing the location of the user of the device. <IMAGE>
