Automatic Speech Signal Analysis for Clinical Diagnosis and by Ladan Baghai-Ravary

By Ladan Baghai-Ravary

Automatic Speech sign research for scientific prognosis and overview of Speech problems provides a survey of tools designed to help clinicians within the prognosis and tracking of speech problems reminiscent of dysarthria and dyspraxia, with an emphasis at the sign processing thoughts, statistical validity of the implications awarded within the literature, and the appropriateness of equipment that don't require really expert gear, conscientiously managed recording tactics or hugely expert group of workers to interpret effects.

Such suggestions provide the promise of an easy and low-budget, but aim, evaluation of various health conditions, which might be of serious worth to clinicians. the best state of affairs could start with the gathering of examples of the consumers’ speech, both over the telephone or utilizing transportable recording units operated via non-specialist nursing employees.

The recordings may possibly then be analyzed first and foremost to assist prognosis of stipulations, and for this reason to watch the consumers’ growth and reaction to therapy. The automation of this procedure might let extra common and typical checks to be played, in addition to delivering better objectivity.

This slightly surprising finding is highlighted in the paper and is left as an issue worthy of further investigation using a larger database. In the field of automatic speech recognition, this latter finding would normally be indicative of a lack of data in one or both of the gender-specific pools used for training. In that case, although an SVM system appears better than RF, when trained on gender-independent data, the same may not be true for gender or agespecific systems trained on a larger dataset.

Gender-independent issue to be resolved more conclusively. 1 Linear Transformations and Discriminant Analysis Castillo-Guerra and Lovey (2003) compared two methods of dysarthria assessment using features extracted from pathological speech signals. One was based on linear discriminant analysis (LDA), while the other was non-linear, based on selforganizing maps. The non-linear method was not only found to give the better classification accuracy, but it also used a 2-dimensional representation which appeared to yield additional information related to the location of any damage in the peripheral or central nervous system.

2009) described the first rahmonic (R1) amplitude measure, investigated the effects of window length and other parameters, and compared it with CPP. e. DC removal from the log power spectrum). Their analysis used a fixed 46 ms (2048 samples) window length. The corresponding results for CPP gave a similar 71 % correlation. These figures might have been more informative if they had calculated the Spearman rank correlation coefficient, rather than simple linear correlation, because the ‘‘best fit’’ straight line to their data clearly did not pass through the origin of the graph, and there is no obvious reason to assume that any correlation with human ratings would be linear in any case.
