Abstract
A method of identifying talker location includes picking up audio signals using a steerable microphone array and processing the picked up audio signals to determine the location of an active talker. The microphone array is then steered in the direction of the active talker and a cue is generated to identify the direction in which the microphone array has been steered.
Claims24
A method of identifying talker location comprising the steps of:
- picking up audio signals using a steerable microphone array;
- processing the picked up audio signals to determine the location of an active talker;
- steering the microphone array in the direction of the active talker;
- and
- generating a cue to identify the direction in which the microphone array has been steered.
A method of identifying talker location comprising the steps of:
- picking up audio signals;
- processing the audio signals to determine the location of an active talker;
- and
- generating a visual cue that identifies the location of said active talker.
A method of identifying talker location comprising the steps of:
- picking up audio signals using a circular microphone array including a plurality of omni-directional microphones;
- processing the picked up audio signals to determine the location of an active talker;
- using the omni-directional microphones to synthesize narrow microphone beams pointing in the direction of the active talker;
- and
- generating a cue to identify the microphone beam focus direction.
A conference unit comprising:
- a loudspeaker to broadcast audio signals;
- a steerable microphone array to pick up audio signals;
- a processor to process picked up audio signals to determine the location of an active talker and steer the microphone array in the direction of said talker;
- and
- an indicator array responsive to said processor and including a plurality of indicators, each indicator being associated with a different microphone array steer direction, the indicator associated with the direction the microphone array has been steered being activated.
