چکیده

In this work we develop a system for enhancement of a speech signal with the highest energy from a linear convolutive mixture of independent sound sources (interferences) recorded by two microphone signals. In this system we use the concept of independent component analysis (ICA) together with auditory lter banks, pitch tracking, adaptive band pass lters and masking. Preliminary computer simulations experiments con rm the validity of the proposed algorithm.

A New Method for Speech Enhancement Based on Incoherent Model Learning in Wavelet Transform Domain

Quality of speech signal significantly reduces in the presence of environmental noise signals and leads to the imperfect performance of hearing aid devices, automatic speech recognition systems, and mobile phones. In this paper, the single channel speech enhancement of the corrupted signals by the additive noise signals is considered. A dictionary-based algorithm is proposed to train the speech...

Speech Enhancement using Laplacian Mixture Model under Signal Presence Uncertainty

In this paper an estimator for speech enhancement based on Laplacian Mixture Model has been proposed. The proposed method, estimates the complex DFT coefficients of clean speech from noisy speech using the MMSE  estimator, when the clean speech DFT coefficients are supposed mixture of Laplacians and the DFT coefficients of  noise are assumed zero-mean Gaussian distribution. Furthermore, the MMS...

شکل‌دهی وفقی و هوشمند پرتو در آرایه‌های میکروفونی Ad-hoc با استفاده از خوشه‌بندی و رتبه‌بندی میکروفون‌ها

Considering the existence of a many speech degradation factors, speech enhancement has become an important topic in the field of speech processing. Beamforming is one of the well-known methods for improving the speech quality that is conventionally applied using regular (classical) microphone arrays. Due to the restrictions in the regular arrangement of microphones, in recent years there has be...

A spatio-temporal speech enhancement scheme for robust speech recognition in noisy environments

A new speech enhancement scheme is presented integrating spatial and temporal signal processing methods for robust speech recognition in noisy environments. The scheme first separates spatially localized point sources from noisy speech signals recorded by two microphones. Blind source separation algorithms assuming no a priori knowledge about the sources involved are applied in this spatial pro...
