Dynamic direction switching for bidirectional in car communication (icc) based on talker row identification

An apparatus, comprising:

• one or more memories;
• one or more processors coupled with the one or more memories, wherein the one or more processors are configured, individually or in combination, to:
• perform cross-correlation on audio signals received from a plurality of microphones in a plurality of seat rows of a vehicle to determine a seat row of the plurality of seat rows from which speech is originating from a loudest talker from among one or more talkers;
• mute a first set of one or more loudspeakers in the seat row of the loudest talker;
• and
• stop operation of one or more adaptive filters on one or more of the speech signals corresponding to one or more feedback paths originating from the one or more loudspeakers that are muted.

A computer-readable medium having instructions stored thereon, wherein the instructions are executable by one or more processors, individually or in combination, to perform a method comprising steps of:

• performing cross-correlation on audio signals received from a plurality of microphones in a plurality of seat rows of a vehicle to determine a seat row of the plurality of seat rows from which speech is originating from a loudest talker from among one or more talkers;
• muting a first set of one or more loudspeakers in the seat row of the loudest talker;
• and
• stopping operation of one or more adaptive filters on one or more of the speech signals corresponding to one or more feedback paths originating from the one or more loudspeakers that are muted.
