One method of operation includes beamforming a plurality of microphone outputs to obtain a plurality of virtual microphone audio channels. Each virtual microphone audio channel corresponds to a beamform. The virtual microphone audio channels include at least one voice channel (135) and at least one noise channel (136). The method includes performing voice activity detection (151) on the at least one voice channel (135) and adjusting a corresponding voice beamform until voice activity detection (151) indicates that voice is present on the at least one voice channel (135). Another method beamforms the plurality of microphone outputs to obtain a plurality of virtual microphone audio channels, where each virtual microphone audio channel corresponds to a beamform, and with at least one voice channel (135) and at least one noise channel (136). The method performs voice recognition on the at least one voice channel (135) and adjusts the corresponding voice beamform to improve a voice recognition confidence metric (159).

A method of providing a Karaoke service to mobile terminals through wireless connection between them. The mobile terminals are grouped as a service group and one of them is designated as a master mobile terminal and the other mobile terminals as slave mobile terminals. The master mobile terminal is connected to a Karaoke service provider through a mobile communication network and controls service content to be received from the Karaoke service provider in all the mobile terminals of the service group. If the master mobile terminal transmits a play command to the slave mobile terminals, all the mobile terminals start to play Karaoke music according to the service contents.
