Patent number: 11670318Abstract: An apparatus and method for auto echo cancellation utilizing an occluded voice sensor. The technology as disclosed and claimed herein and the various implementations and embodiments improves Acoustic Echo Cancellation (AEC) system performance by increasing cancellation quality and speech SNR by the replacement of the lower frequency portion of the microphone signal with the signal of an Occluded Voice Sensor (OVS) signal and never including the spectral band in the transmission. This frequency band replacement excludes the reinjection of that band from the speaker.Type: GrantFiled: May 14, 2021Date of Patent: June 6, 2023Assignee: DSP Concepts, Inc.Inventor: Gints Klimanis
