- Study and proposal of parameters for the objective assessment of voice quality in smokers José Antonio Díaz A. Antonio Arroyo Howard B. Rothman Ingeniería Speech models Speech processing Speech pathologies Digital signal processing Objective classification of speech For this study, 20 speech samples from non-smokers and smokers were taken, and 14 parameters were selected and implemented in Matlab from the information found in the literature about the objective classification of speech samples. In addition, 6 new parameters were designed in order to determine speech quality. These parameters were modeled after and designed from parameters found in the literature and implemented in Matlab for a total of 20 parameters. A software package designed by one of the authors was selected and used in order to extract the fundamental frequency and amplitude waves from the 20 chosen samples. From these waves, the values of the 20 parameters for speech quality measurement were obtained, with the objective of assessing each parameter. Finally, conclusions were drawn. 2014 artículo científico 1316-6832 https://www.redalyc.org/articulo.oa?id=70732643002 en http://www.redalyc.org/revista.oa?id=707 Revista INGENIERÍA UC application/pdf Universidad de Carabobo Revista INGENIERÍA UC (República Bolivariana de Venezuela) Num.3 Vol.21
