Microphone Array Wiener Beamformer and Speaker Localization

Производитель: "LAP Lambert Academic Publishing"

Book Statement: A microphone array is the promising solution for realizing hands-free speech recognition in real environments. Accurate talker localization is very important for speech recognition using the microphone array. However localization of a moving talker is difficult in noisy reverberant environments. The talker localization errors degrade the performance of speech recognition. A speech recognition algorithm is implemented to solve the problem, which considers multiple talker direction hypotheses. Abstract: This book describes the design and implementation of a speech enhancement system that uses 4-channel microphone array beam forming and speech enhancement algorithms applied to a speech signal in a multiple source environment. To locate the accurate Direction of Arrival (DOA) from the source, it is necessary to design a suitable microphone array system with more efficient localization algorithm. The goal of the system is to improve the quality of the primary speech signal.... ISBN:9783659174070
