Abstract: A headset is constructed to generate an acoustically distinct speech signal in a noisy acoustic environment. The headset positions a pair of spaced-apart microphones near a user's mouth. The microphones each receive the user s speech, and also receive acoustic environmental noise. The microphone signals, which have both a noise and information component, are received into a separation process. The separation process generates a speech signal that has a substantial reduced noise component. The speech signal is then processed for transmission. In one example, the transmission process includes sending the speech signal to a local control module using a Bluetooth radio.

Abstract: A method of signal processing includes calculating a range based on information from a reflected ultrasonic signal. Based on the calculated range, one among a plurality of direction-of-arrival (DOA) estimation operations is selected. The method also includes performing the selected operation to calculate an estimated direction of arrival (DOA) of an audio-frequency component of a multichannel signal. Examples of DOA estimation operations include operations based on phase differences between channels of the multichannel signal and operations based on a difference in gain between signals that are based on channels of the multichannel signal.
Abstract translation: 信号处理的方法包括基于来自反射的超声波信号的信息来计算范围。 基于计算出的范围，选择多个到达方向（DOA）估计操作中的一个。 该方法还包括执行所选择的操作以计算多声道信号的音频分量的估计到达方向（DOA）。 DOA估计操作的示例包括基于多信道信号的信道之间的相位差的操作和基于基于多信道信号的信道的信号之间的增益差异的操作。

Abstract: A method for echo cancellation and noise suppression is disclosed. Linear echo cancellation (LEC) is performed for a primary microphone channel on an entire frequency band or in a range of frequencies where echo is audible. LEC is performed on one or more secondary microphone channels only on a lower frequency range over which spatial processing is effective. The microphone channels are spatially processed over the lower frequency range after LEC. Non-linear noise suppression post-processing is performed on the entire frequency band. Echo post-processing is performed on the entire frequency band.
Abstract translation: 公开了一种用于回波消除和噪声抑制的方法。 线性回波消除（LEC）是在整个频带上的主要麦克风通道或在可听见回声的频率范围内执行的。 只有在空间处理有效的较低频率范围上的一个或多个辅助麦克风通道上执行LEC。 麦克风通道在LEC之后的较低频率范围内进行空间处理。 在整个频带上执行非线性噪声抑制后处理。 在整个频带上执行回波后处理。
