Basis Pursuit applied to Speech Signals
نویسندگان
چکیده
In the present paper the method of Basis Pursuit with an overcomplete dictionary is applied to a set of phonemes chosen from the TIMIT database. Emphasis is placed on an analysis of the sparseness of the representation, and its relation to the preservation of the important acoustic cues for the phoneme group. A comparison with other methods, such as Method of Frames, Matching Pursuit and Best Orthogonal Basis is also given.

Structure-Constrained Basis Pursuit for Compressed Sensing
In compressive sensing (CS) theory, as the number of samples is decreased below a minimum threshold, the average error of the recovery increases. Sufficient sampling is either required for quality reconstruction or the error is resignedly accepted. However, most CS work has not taken advantage of the inherent structure in a variety of signals relevant to engineering applications. Hence, this pa...
متن کاملAnalysis of Spanish synthesized speech signals using spectral and basis pursuit representations
speech, the sounds involved in an utterance are not produced independently of one another, but rather reflect the result of a complex process of sound concatenation. It is important to study these coarticulation effects in representations of speech signals since, for example, their cues can be helpful in the development of robust speech recognition systems. Representational tools, such as the s...
متن کاملBasis Pursuit Decomposition: An Analysis of Spanish Words
Time-frequency representations (TF) of speech signals are commonly used to visualize the dynamic behavior. However the choice of the basis functions employed in the TF has an important effect on the number of nonzero coefficients occurring in the representation of the signal. Signals with different morphologies, such as vowels or fricatives, could benefit from the use of different bases for eac...
متن کاملPMU-Based Matching Pursuit Method for Black-Box Modeling of Synchronous Generator
This paper presents the application of the matching pursuit method to model synchronous generator. This method is useful for online analysis. In the proposed method, the field voltage is considered as input signal, while the terminal voltage and active power of the generator are output signals. Usually, the difference equation with a second degree polynomial structure is used to estimate the co...
متن کاملUnderdetermined Anechoic Blind Source Separation
In this paper, we address the problem of under-determined Blind Source Separation (BSS) of anechoic speech mixtures. We propose a demixing algorithm that exploits the sparsity of certain time-frequency expansions of speech signals. Our algorithm merges `-basis-pursuit with ideas based on the degenerate unmixing estimation technique (DUET) [1]. There are two main novel components to our approach...
