Classification of voiceless plosives using wavelet packet based approaches

2000 10th European Signal Processing Conference, 2000

  • Classification of voiceless plosives using wavelet packet based approaches

    There are contradictory reports on the usefulness of the Wavelet Packet Transform for feature extraction. In this paper we continue the investigation of this subject with reference to non-stationary speech signals, namely unvoiced plosive consonants /p/,/t/, /k/. We concentrate on the influence of the feature reduction method on the classification rate. Two strategies have been applied: feature selection, performed using the Local Discrimination Basis and feature projection performed using Primary Components Analysis (Singular Value Decomposition). Classification has been performed by cluster analysis and neural network. The classification results obtained for PCA outperform those for LDB and other methods examined earlier.

  • Perceptual coding of speech using a fast wavelet packet transform algorithm

    This paper presents a new speech coding algorithm based on a fast wavelet packet transform algorithm and psychoacoustic modeling. The employed FFT-like overlapped block orthogonal transform allows us to approximate the auditory critical band decomposition in an efficient manner, which is a major advantage over previous approaches. Owing to such a decomposition of the original signal, we make use of the human ear masking properties to decrease the mean bit rate of the encoder.

    Wavelet transform is widely used in feature extraction and pattern recognition, the choice of wavelet basis directly affects the processing result. This paper constructs feature vector based on the continuous wavelet transform coefficients, The method of selecting the best wavelet base is extracted combined the general characteristics with distance criterion and proposed two feature optimization methods. Three types of actual underwater acoustic targets signal is used to validate the optimization method. The classification results show that the two methods can improve the recognition accuracy under the optimal wavelet basis. For different characteristics, the optimization effect is different.

  • Wheeze Detection and Location using Spectro-temporal Analysis of Lung Sounds

    Wheezes are abnormal lung sounds, which usually imply obstructive airways diseases. The objective of this study is to design an automatic wheeze detector for a wearable health monitoring system, which is able to locate the wheezes inside the respiratory cycle with high accuracy, and low computational complexity. We compute important features of wheezes, which we classify as temporal and spectral characteristics and employed to analyze recorded lung sounds including wheezes from patients with asthma. Time-frequency (TF) technique as well as wavelet packet decomposition (WPD) is used for this purpose. Experimental results verify the promising performance of described methods.

  • A NOVEL WAVELET PACKET BASED DIRECTION OF ARRIVAL ESTIMATION FOR SPECTRUM SENSING IN COGNITIVE RADIO NETWORKS

    Spectrum Sensing is the quintessence of Cognitive Radio Network and helps in decongesting the RF band. A lot of research has already been done in detection of free space in the frequency spectrum and the need of the hour is exploitation of a novel characteristic of a signal from a newer perspective. Cognitive radio works in a multi-antenna based system with a number of secondary user sensors wherein the signals from primary user is received from different directions. Thus, the angle dimension of the received signal can also be exploited to propose new sensing schemes. In this paper, a novel technique based on direction of arrival estimation has been augmented with wavelet packet decomposition to enhance the performance characteristics in case of closely-spaced DOA and low SNR. The proposed algorithm provides high resolution as well as significantly reduced computation load. The better performance and reliability of the proposed WDOA estimation have been experimentally validated and presented in form of computer simulations.

  • A Novel Wavelet Packet Speech Enhancement Algorithm Based On Time-Frequency Threshold

    Threshold choosing is critical in wavelet speech enhancement. In the paper, a novel wavelet packet speech enhancement algorithm is presented based on time- frequency (TF) threshold. Different from the conventional methods in threshold choosing, e.g. invariant threshold and time-variant threshold, the proposed threshold is modulated according to speech TF details other than rough envelops adopted in the recent algorithms based on eager energy operator (TEO) and adaptive noise estimation (ANE). In the new algorithm, the speech TF information is obtained from the frequency-based pre-estimate, and the threshold is modulated with TF characteristic of the pre-estimate. Then via thresholding the wavelet packet coefficients, the contaminated speech can be denoised adaptively. Compared with the former wavelet based algorithms, the proposed algorithm offers more pleasant enhanced speech with less distortion and residual noise in additive Gaussian noise case. Experimental results show its better performance in subjective test, input and output SNR test and modified bark spectral distortion measurement (MBSD).

  • Normalization method based on rough set theory and application in fault line detection

    The training time of classifier based on neural network is very long using the conventional normalization when the distances between samples of different classes are too small. To overcome the disadvantage, the normalization method based on rough set theory is proposed. By normalizing samples using rough ser theory, the samples which are near but belong to different classes are taken apart. The normalized samples are used to train neural network The method is applied into neural network based fault line detection for distribution network The simulation results show that the training time of neural network with processed samples is shorter markedly.

  • Application of the wavelet packet transform to flaw detection in ultrasound B-scans

    An important issue in ultrasonic nondestructive evaluation is the detection of flaw echoes in the presence of coherent background noise associated with the microstructure of materials. Many signal processing techniques have proven to be useful for this purpose. However, when considering B-scan images, it appears that fully two-dimensional robust flaw detection techniques remain desirable. In this paper, we describe a novel automatic flaw detection method based on the wavelet packet transform, which is particularly well adapted to B-scan image analysis. Some experimental detection results in B-scan images of austenitic stainless steel samples comprising artificial flaws are also presented.

  • Time frequency analysis and spatial filtering in the evaluation of beta ERS after finger movement

    Different methods are compared for the evaluation of the event related synchronization (ERS) in the beta rhythm corresponding to finger movements. In addition to the standard procedure usually employed, the realistic Surface Laplacian (SL) is here introduced to improve the spatial localization of the phenomenon, while a Wavelet Packet (WP) decomposition approach is intended to better detect the time dependent characteristics. The parameters of interest (ERS amplitude and latency) were statistically analyzed through Analysis of Variance (ANOVA) and Scheffe's test. The WP filtering results are well comparable with the traditional filtering procedure. On the other hand, the realistic SL considerably improves the spatial localization and the consistency of the estimation (decreased variance) of the ERS amplitude.
