Embodiment Construction

[0028] In this article, refer to Figure 1 to Figure 3 depicts the bluetooth TM (Bluetooth TM ) implementation of a dual-earpiece communication earphone, the communication earphone includes an audio system on chip and a digitally controlled analog circuit. However, the parallel signal processing techniques described below for providing self-speech feedback to a headset wearer are applicable to any wired or wireless, circumaural, on-ear, or in-ear communication headset that includes an earpiece or a pair of earpieces.

[0029] figure 1 A communication headset 100 is shown comprising a left earpiece 102 and a right earpiece 104 connected by a headband 106 . Each earpiece 102 , 104 includes a respective earcup 108 , 110 and pad 112 , 114 . The ear straps exert a force in an inward direction indicated by arrow 116 . The headset 100 is operable to communicate via Bluetooth with a paired mobile phone 120 TM Link 118 transmits and receives signals, including audio signals.

Abstract

Techniques for providing self-voice feedback in a communications headset include processing signals carrying near-end speech in parallel digital and analog signal processing paths to produce a combined gain-adjusted near-end signal carrying the near-end speech for output to transducers of the communications device. A first ear cup and a second microphone (202, 204) provide a first signal and a second signal, and a first signal processing circuit (212) determines microphone hybrid parameter values and gain adjustment parameter values through the first signal and the second signal. The first signal processing circuit mixes the first signal and the second signal to generate a gain-adjusted starting signal. A second signal processing circuit generates a combined gain-adjusted near-end signal which carries the near-end speech for providing output to output transducers (206, 208) in the first ear cup and a second ear cup.

Description

technical field [0001] The present disclosure relates to providing self-voice feedback in a communication headset. Background technique [0002] Wired or wireless communication headsets suitable for use in multi-way communication over a telecommunications system typically include a microphone for detecting near-end speech uttered by the wearer of the headset. In high noise environments, the microphone also picks up ambient noise such as speech by people near the headset wearer and wind noise due to air passing over the microphone. These noises, if transmitted to the far-end party of the phone, would interfere with the audible quality of the conversation between the headset wearer and the far-end party. [0003] The wearer of a communication headset having earcups for closing the wearer's ears will experience what is commonly referred to as the occlusion effect, which causes the wearer to perceive that his voice has been overemphasized low frequencies and high frequencies t...
