Speech Coding, Synthesis, and Compression, quantization error. Experimental results show that WT-based coders deliver superior quality to some audio standards when operating at the same bit rate and they deliver comparable quality to other codecs at lower bit rates. As a result, speech coding with WT can provide an efficient and flexible scheme for audio compression.

Wavelets, Wavelet Filters, and Wavelet Transforms,er coding or identified for recognition. The wavelets are considered one of such efficient methods for representing the spectrum of speech signals. Wavelets are used to model both production and perception processes of speech. Wavelet-based features prove a success in a widespread area of practical

Spectral Analysis of Speech Signal and Pitch Estimation,wavelet theory permits the introduction of the concepts of signal filtering with different bandwidths or frequency resolutions. As both time and frequency analysis can be conducted by WT, the tree structure of WP analysis can be customized to match the critical bands of human hearing giving better s

Speech Detection and Separation, speech from other signals. Many works report better detection and separation performance using wavelet analysis than using other techniques. On another level, as segmentation of speech into many classes is so hard, WT is well localized in time-frequency domain, and boundaries of speech segments can

Speech Recognition,ecognition process may perform better. Alternatively, wavelet-based features can be added to other successful features to improve recognition performance. Third, wavelets can serve as an activation function in neural-networks employed for speech recognition. Hybrid methodology may comprise a mix of

Speech Coding, Synthesis, and Compression,he wavelet synthesis filter and a controlled bit allocation to the wavelet coefficients help to minimize the perceptually significant noise due to the quantization error. Experimental results show that WT-based coders deliver superior quality to some audio standards when operating at the same bit ra
