Application of acoustic analysis of speech signal for evaluation of intubation-related damages of the speech organ
نویسندگان
چکیده
Endotracheal intubation is a method commonly applied nowadays in medicine, particularly in surgical procedures carried out under general anaesthetic. It is however an invasive method which may result in many complications, including mechanical injuries of the larynx [1]. The problem is not of purely medical nature. However from the research point of view the detailed analysis of vocal folds damages is necessary. In the present work the attention is mainly focused on the prospects of application of a dedicated acoustical analysis of the speech signal, based on professional methods of signal processing. In the field considered in the present work the objectives of the signal processing and classification are different from the usual ones (revealing the origins of the deformation and evaluation of the signal deformation level in relation to the standard. The acoustic and phonetic properties of the signal itself are essentially different from the widely known parameters of correct speech.

Speech recognition is a subfield of artificial intelligence that develops technologies to convert speech utterance into transcription. So far, various methods such as hidden Markov models and artificial neural networks have been used to develop speech recognition systems. In most of these systems, the speech signal frames are processed uniformly, while the information is not evenly distributed ...

Accurate gender classification is useful in speech and speaker recognition as well as speech emotion classification, because a better performance has been reported when separate acoustic models are employed for males and females. Gender classification is also apparent in face recognition, video summarization, human-robot interaction, etc. Although gender classification is rather mature in a...

Objective Stuttering is a developmental disorder of speech fluency with unknown causes. One of the proposed theories in this field is deficits in speech motor control that is associated with damaged control, timing, and coordination of the speech muscles. Fundamental frequency, fundamental frequency range, intensity, intensity range, and voice onset time are the most important acoustic componen...

Although, speech recognition systems are widely used and their accuracies are continuously increased, there is a considerable performance gap between their accuracies and human recognition ability. This is partially due to high speaker variations in speech signal. Deep neural networks are among the best tools for acoustic modeling. Recently, using hybrid deep neural network and hidden Markov mo...
