ROBUST SPEAKER RECOGNITION INTEGRATING PITCH AND

In this paper, a novel source separation speech enhancement system is proposed that combines binaural Wiener filtering (BWF) pre-processing and corrected rate based target speech selection. We aimed to develop a flexible approach that combines the strengths of BSS techniques with noise reduction algorithms.

Restoration, Wiener filter, Auto correlation, Speech recognition, Speech quality. 1. Introduction. Speech is one of the supreme efficient methods of communication to transfer the information from source to destination users. For distant communication from source to destination undergo with different environments. This different environment degrades the information varying speech signal. So

NOISE ROBUST SPEAKER IDENTIFICATION FOR SPONTANEOUS ARABIC

The speech signal in general is corrupted by noise and the noise signal does not affect the speech signal uniformly over the entire spectrum. An improved Wiener filtering method is proposed in this paper for reducing background noise from speech signal in colored noise environments. In view of nonlinear variation of human ear sensibility in

Experiences in Groups has been described as ‘a landmark in thought and conceptualization of the unconscious functioning of human beings in groups’ (Lawrence et al., 1996: 28). Over more than 50 years, it has proved influential in the development of academic and applied approaches to research, consultancy, executive coaching, group work, and management and leadership development. It has
