Resumen
En el presente estudio se expone acerca de parámetros acústicos tanto locutivos (frecuencia fundamental e intensidad) como de calidad vocal (CPPs, L1-L0 y Alpha ratio), buscando demostrar diferencias significativas al medir y comparar los resultados en los parámetros mencionados en dos poblaciones, urbanas y rurales de Chile, pertenecientes a las provincias de Santiago y Castro respectivamente. Para esto se recopilaron conceptos de anatomía y fisiología de la voz, concepto de voz normal y análisis acústico de la voz.
En cuanto a la metodología, esta investigación es de enfoque mixto con un diseño no experimental de tipo transversal con alcance descriptivo y correlacional. La muestra estuvo compuesta por 97 jóvenes entre 17 y 23 años, de los cuales 30 fueron de la ciudad de Castro y 67 de Santiago. Estas se recolectaron mediante la grabación de las voces de los sujetos frente a diferentes estímulos con el software “Audacity”, las cuales fueron posteriormente estudiadas en softwares Praat 6.0.29, Speech tool o Ztool y estadísticamente por IBM SPSS Statistics. Añadido a lo anterior, se cuenta con un cuestionario de autopercepción, que permitió el análisis de la percepción y conformidad de los sujetos frente a su voz.
Respecto a los resultados obtenidos en el análisis acústico de la voz de las muestras y en el cuestionario de autopercepción vocal, se desprende que los individuos de Santiago y Castro sienten que las características entonacionales de su habla son distintas entre las dos zonas, sin embargo, las afirmaciones que hacen referencia a parámetros vocales como lo son intensidad y frecuencia fundamental no difieren de manera importante entre los sujetos de las diferentes localidades
In this study, we present about both acoustic parameters (fundamental frequency and intensity) and vocal quality (CPPs, L1-L0 and Alpha ratio), seeking to demonstrate significant differences when measuring and comparing the results in the mentioned parameters in two populations, urban and rural areas of Chile, belonging to the provinces of Santiago and Castro respectively. For this, concepts of voice anatomy and physiology, normal voice concept and acoustic voice analysis were collected. Regarding the methodology, this research is of mixed approach with a non-experimental design of transversal type with descriptive and correlational scope. The sample consisted of 97 young people between 17 and 23 years old, of which 30 were from the city of Castro and 67 from Santiago. These were collected by recording the voices of the subjects in front of different stimuli with the software "Audacity", which were later studied in software Praat 6.0.29, Speech tool or Ztool and statistically by IBM SPSS Statistics. Added to the above, there is a self-perception questionnaire that allowed the analysis of the perception and compliance of the subjects in front of their voice. Regarding the results obtained in the acoustic analysis of the voice of the samples and in the questionnaire of vocal self-perception, it is clear that the individuals of Santiago and Castro feel that the intonational characteristics of their speech are different between the two zones, however, The statements that refer to vocal parameters such as intensity and fundamental frequency do not differ significantly between the subjects of the different localities.
