Using Adaptive Signal Limite Weighting Techniques for Noisy
نویسنده
چکیده
In an automatic speech recognition (ASR) system, environmental mismatch between speech models and testing speech utterances causes serious performance degradation. To alleviate this environmental mismatch problem, smoothing process and weighting technique are two of the most widely used methods. In this paper, an investigation is presented into the feasibility of combining an adaptive signal limiter with a weighting technique for seeking further performance improvement in noisy speech recognition.

A Convolutional Neural Network based on Adaptive Pooling for Classification of Noisy Images
Convolutional neural network is one of the effective methods for classifying images that performs learning using convolutional, pooling and fully-connected layers. All kinds of noise disrupt the operation of this network. Noise images reduce classification accuracy and increase convolutional neural network training time. Noise is an unwanted signal that destroys the original signal. Noise chang...

متن کاملAdaptation of Rejection Algorithms for a Radar Clutter
In this paper, the algorithms for adaptive rejection of a radar clutter are synthesized for the case of a priori unknown spectral-correlation characteristics at wobbulation of a repetition period of the radar signal. The synthesis of algorithms for the non-recursive adaptive rejection filter (ARF) of a given order is reduced to determination of the vector of weighting coefficients, which realiz...

متن کاملSpeech Enhancement Using Adaptive Kalman Filter Combined With Perceptual Weighting Filter
The speech enhancement is one of the important techniques used to improve the quality of a speech signal i.e. degraded by noise. Speech enhancement using conventional kalman filter require calculating the parameters of AR (auto-regressive) model, and performing a lot of matrix operations, which is non-adaptive. In this paper the proposed method i.e. adaptive kalman filter combined with perceptu...
