US 2022/0189497 A1 · BONE CONDUCTION HEADPHONE SPEECH ENHANCEMENT SYSTEMS AND METHODS

Abstract

Systems and methods for enhancing a headset user's own voice include at least two outside microphones, an inside microphone, audio input components operable to receive and process the microphone signals, a voice activity detector operable to detect speech presence and absence in the received and/or processed signals, and a cross-over module configured to generate an enhanced voice signal. The audio processing components includes a low frequency branch comprising low pass filter banks, a low frequency spatial filter, a low frequency spectral filter and an equalizer, and a high frequency branch comprising highpass filter banks, a high frequency spatial filter, and a high frequency spectral filter.

Dependent claims

A method for enhancing a headset user's own voice comprising:

receiving a plurality of external microphone signals from a plurality of external microphones configured to sense external sounds through air conduction;
receiving an internal microphone signal from an internal microphone configured to sense a bone conduction sound from the user during speech;
processing the external microphone signals and internal microphone signals through a lowpass process comprising a low frequency spatial filtering and low frequency spectral filtering of each signal;
processing the external microphone signal through a highpass process comprising high frequency spatial filtering and high frequency spectral filtering of each signal;
and
mixing the lowpass processed signals and highpass processed signals to generate an enhanced voice signal.
