VEHICLE VOICE ACQUISITION SYSTEM WITH MICROPHONE AND OPTICAL SENSOR
First Claim
1. A voice acquisition system for a vehicle, said voice acquisition system comprising:
- an optical sensor disposed at an interior portion of the vehicle and having a sensing field that encompasses a driver'"'"'s head region in the vehicle cabin typically occupied by a driver'"'"'s head;
an optical sensor processor for processing an output of said optical sensor to determine vibrations of the driver that are indicative of vocal signals emanating from the driver;
a microphone operable to receive audible signals from in the vehicle cabin;
a microphone processor for processing an output of said microphone; and
a control, wherein said control, responsive to processing of said output of said optical sensor by said optical sensor processor and processing of said output of said microphone by said microphone processor, isolates the driver'"'"'s voice from other acoustic noise.

Abstract
A voice acquisition system for a vehicle includes an optical sensor disposed at an interior portion of the vehicle and having a sensing field that encompasses a driver'"'"'s head region in the vehicle cabin typically occupied by a driver'"'"'s head. An optical sensor processor is provided for processing an output of the optical sensor to determine optically-derived vocal signals emanating from the driver. A microphone is provided and is operable to receive audible signals from in the vehicle cabin. A microphone processor is provided for processing an output of the microphone to determine audio-derived vocal signals emanating from the driver. A control, responsive to processing of the output of the optical sensor by the optical sensor processor and processing of the output of the microphone by the microphone processor, isolates the driver'"'"'s voice from other acoustic noise.

16. A voice acquisition system for a vehicle, said voice acquisition system comprising:
-
an optical sensor comprising an interferometer disposed at an interior portion of the vehicle and having a sensing field that encompasses a driver'"'"'s head region in the vehicle cabin typically occupied by a driver'"'"'s head; an optical sensor processor for processing an output of said interferometer to determine vibrations of the driver that are indicative of vocal signals emanating from the driver; wherein a laser generator that emits a laser light beam toward the driver'"'"'s head region, and wherein said interferometer senses the emitted laser light beam at the driver'"'"'s head region; a camera having a field of view that encompasses the driver'"'"'s head region, and wherein an aim of the laser generator is adjusted responsive to image processing of image data captured by said camera; a microphone operable to receive audible signals from in the vehicle cabin; a microphone processor for processing an output of said microphone; and a control, wherein said control, responsive to processing of said output of said interferometer by said optical sensor processor and processing of said output of said microphone by said microphone processor, isolates the driver'"'"'s voice from other acoustic noise. - View Dependent Claims (17, 18, 19, 20)
