Abstract
A conversation assistance system with a bi-lateral array of microphones arranged externally of a space that does not include any array microphones, where the space has a left side, a right side, a front and a back, the array comprising a left side sub-array of multiple microphones and a right side sub-array of multiple microphones, where each microphone has a microphone output signal, and a processor that creates from the microphone output signals a left-ear audio signal and a right-ear audio signal. The left-ear audio signal is created based on the microphone output signals from one or more of the microphones of the left-side sub-array and one or more of the microphones of the right-side sub-array and the right-ear audio signal is created based on the microphone output signals from one or more of the microphones of the left-side sub-array and one or more of the microphones of the right-side sub-array.
