Description: Normally speech signals are contaminated with noise and interference that reduces the intelligibility of speech during communication. In order to make speech
signals e ective and useful, they need to be enhanced from the noisy speech signal.
In speech processing eld many speech enhancement techniques are developed and
are providing very good results.
Multichannel microphone array is also one of the techniques used for speech
enhancement, that provides better results than the single channel speech enhancement. Moreover, Wiener ltering is the most commonly used technique for
multichannel microphone array for speech enhancement. The main focus of this
thesis is to implement multichannel microphone array using Wiener ltering in
the modulation domain system and also in the time domain system to enhance
the speech. Platform: |

Description: The material in this work is organized into five chapters, including this one. The
focus is on the time-domain algorithms for both the single and multiple microphone
cases. The work discussed in these chapters is as follows.
In Chap. 2, we study the noise reduction problem with a single microphone by
using a filtering vector for the estimation of the desired signal sample.
Chapter 3 generalizes the ideas of Chap. 2 with a rectangular filtering matrix for
the estimation of the desired signal vector.
In Chap. 4, we study the speech enhancement problem with a microphone array
by using a long filtering vector.
Finally, Chap. 5 extends the results of Chap. 4 with a rectangular filtering matrix Platform: |

Description: 使用麦克风阵列的声源定位和跟踪已成为室内声学，电话会议系统和声音产生对象的跟踪的关注焦点。估计源定位的当前方法取决于麦克风对之间的传统时间延迟估计技术，然而，忽略环境噪声，来自周围的反射和封闭空间中的混响。在本研究中，设计并开发了基于3D麦克风阵列的声源定位器和跟踪器（ASLT），用于实时源检测和定位。(Acoustic source localization and tracking using microphone arrays has become a focus of interest in room acoustics, teleconference systems and tracking of sound producing objects. The current methods to estimate the source localization depend on conventional time-delay estimation techniques between microphone pairs, however, ignoring the ambient noise, reflections from surrounding and reverberation in the closed space. In this study, an acoustic source localizer and tracker (ASLT) based on 3D microphone array is designed and developed for real time source detection and localization.) Platform: |
