One of the problems of the Automatic Speech Recognition systems is the voice’s changes. Typically, a person can have voluntary and involuntary voice’s changes and the system can get confused in these cases, also the ...

This project aims to lay the foundations for a system with a potential to develop, used for a higher level of security based on characteristics of the human voice such as fundamental frequency, Mel's Coefficient of ceptral ...

The speech recognition systems consist of three principal parts: preprocessing, features extraction and vectors classification. This paper considers the voice changes, voluntary and involuntary changes, and how this affects ...

Binary classifier to isolate the sound of coughing from other sounds such as speech, ambient noise etc. Mel's coefficients are extracted using HTK software and using a standard mathematical algorithm, subsequently spectrograms ...

La presente tesis de grado propone el desarrollo de un sistema biométrico audio-visual para el reconocimiento e identificación de personas. La parte del audio corresponde al reconocimiento del locutor y la parte visual al ...

Las Redes Neuronales Artificiales están inspiradas en las redes neuronales biológicas del cerebro humano. Están constituidas por elementos que se comportan de forma similar a la neurona biológica en sus funciones más ...
