An effective hands-free speech interface with an appropriate digital signal processing is essential for teleconference systems and control systems. Beamforming technique, which use a microphone array (MA) is an ideal solution for distant - talking speech acquisition, is one of the most attractive approaches for suppressing background noise and improving the speech intelligibility and speech quality of the processing system. Minimum Variance Distortionless Response (MVDR) has the capacity of maximizing the sensitivity in a certain direction at aiming to extract the desired target speech while removing all total power of surrounding noise. However, in many complex recording environments, due to the error of direction of arrival of interest speaker, the difference of microphone sensitivities, imprecise designed geometry of MA, the performance of MVDR beamformer often degraded. In this contribution, the authors suggested an additive post-filtering to enhance the effectiveness of MVDR beamformer. © 2023 IEEE.

Speech processing devices such as mobile telephone, hearing aid, cochlear implant is commonly equipped with a designed microphone array (MA) to capture the acoustic environment. The MA signals often contain a mixture of desired speech component and unwanted surrounding noise (a combination of reverberation, different interferences, complex recording environment, third-party speaker). Minimum Distortionless Variance Response (MVDR) beamformer is one the most useful methods for reducing background noise and improving speech enhancement has been recently studied. MVDR beamformer merges the predefined constraints of response from a priori relative transfer function and the criteria of minimum total output noise power. Because of the microphone mismatches, the different microphone sensitivities, or the error of the direction of arrival of the interest signal, the output final signal of MVDR beamformer often corrupted. In this paper, the authors proposed an additive gain function for reducing speech distortion and enhancing MVDR beamformer's performance. © 2023 IEEE.

Noise suppression and understanding speech in a complex environment with the presence of numerous and dominant surrounding noise is very difficult for humans. To deal with this problem, microphone array, which exploit a priori information of designed geometry of microphone array, the direction of arrival (DOA) of interest signal or the properties of recorded situation, is used with aiming at preserving the desired speaker without speech distortion while reducing background noise. Generalized Sidelobe Canceller (GSC) beamformer has been installed in almost all acoustic equipment, hearing aids, mobile phones. Unfortunately, the performance of GSC beamformer is often corrupted in many scenarios, such as imprecise DOA, microphone mismatches or different microphone sensitivities. In this paper, a spectral mask - based suggested algorithm to reduce the speech leakage in the reference signal of GSC beamformer. The proposed method is evaluated for increasing the speech quality of dual - microphone systems. © 2023 IEEE.

A New Approach for Enhancing MVDR Beamformer’s Performance 12th

A New Approach for Enhancing MVDR Beamformer’s Performance

Proceedings of the12th International Conference on Information Technology and its Applications, CITA 2023

Minimum Variance Distortionless Response (MVDR) has many applications in the microphone array processing approach due to its advantages of suppressing background noise, interference, or third-party speaker. However, in real-life recording situations, the performance of the MVDR beamformer is often degraded by microphone mismatches, different microphone sensitivities, or errors in microphone distribution. Therefore, in this paper, the authors suggested a new approach, which uses an additive matrix for modifying the covariance matrix of observed microphone array data. The illustrated experiments were evaluated in a living room with a dual-microphone system (DMA2) and a stand speaker in the presence of noise. The theoretical results are further confirmed in terms of the signal-to-noise ratio (SNR) and the speech intelligibility of the output signal. The proposed method can be integrated into systems with multiple microphones and in annoying complex environments. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
