    摘要： The invention discloses a method and a device for reducing voice reverberation based on double microphones. The method comprises the steps of calculating a transfer function h ( t ) from a secondary microphone to a primary microphone according to an input signal x 2 ( t ) of the primary microphone and an input signal x 1 ( t ) of the secondary microphone; judging the strength of reverberation according to h(t) and calculating a regulatory factor β of a gain function by taking a tail section h r ( t ) of the h ( t ); obtaining a late reverberation estimation signal r̂ ( t ) of x 2 ( t ) with the convolution of x 1 ( t ) and h r ( t ); calculating the gain function according to the frequency spectrum of x 2 ( t ), β and frequency spectrum of r̂ ( t ); obtaining the reverberation removed frequency spectrum of x 2 ( t ) by multiplying the frequency spectrum of x 2 ( t ) by the gain function; and obtaining a late reverberation removed time-domain signal of x 2 (t) by frequency-time conversion. Thus, the late reverberation can be removed from the input signal of the primary microphone, early reverberation can be preserved, processed voice is not caused to be thin, and the voice quality is improved. Meanwhile, spectral subtraction intensity is adjusted according to the strength of the reverberation so as to ensure that the voice is not damaged on the condition that the reverberation is weak and the voice intelligibility is originally high. Accurate estimation of DOA of direct sound is not needed, and therefore the microphones are not required to have high consistency.

    摘要翻译： 本发明公开了一种基于双麦克风减少语音混响的方法和装置。 该方法包括以下步骤：根据主麦克风的输入信号x2（t）和次麦克风的输入信号x1（t）计算从次麦克风到主麦克风的传递函数h（t）; 根据h（t）判断混响的强度，并通过取h（t）的尾部hr（t）来计算增益函数的调节因子β; 利用x1（t）和hr（t）的卷积获得x2（t）的后期混响估计信号r（t）; 根据x2（t），β的频谱和r（t）的频谱计算增益函数; 通过将x2（t）的频谱乘以增益函数来获得x2（t）的混响去除频谱; 并通过频率 - 时间转换获得x2（t）的后期混响消除时域信号。 因此，可以从主麦克风的输入信号中去除后期混响，可以保留早期混响，不会使处理后的声音变细，并且改善语音质量。 同时根据混响的强弱来调整谱减强度，以保证在混响较弱且语音清晰度本来就很高的情况下，语音不受损坏。 直接声音的DOA的准确估计是不需要的，因此麦克风不需要具有高一致性。
