Resumen
Introducción

El fonetograma (F) es la representación gráfica del potencial fonatorio de un individuo. El F obtenido empleando un sonómetro y un analizador de frecuencias se denomina “fonetograma manual” (FM), y el obtenido mediante programas informáticos se denomina “fonetograma automático” (FA).

Material y métodos

Se ha realizado en 12 cantantes líricos un FM standard y un FA con el programa Dr. Speech Science 3.0, midiendo la correlación entre ambos sistemas.

Resultados

Se objetivó una diferencia entre los dos sistemas para 14 de las 15 medidas fonetométricas con una p0,0005, y con una p0,05 para la restante, siendo los resultados numéricos del FA habitualmente mayores que los del FM, mostrando una correlación entre los resultados de ambos métodos.

Conclusiones

El FA obtenido con el programa Dr. Speech Science 3.0 es un sistema más rápido y sencillo que el empleado para el FM, mostrando sin embargo diferencias por exceso respecto al FM en todos los parámetros fonetométricos habituales.

Abstract
Introduction

The phonetogram (F) is the graphic representation of a person phonatory potential. The F carried out with a sonometer and a frequency analyser is what is called “manual phonetogram” (MPh), and the one obtained by means of a computer is called the “automatic phonetogram” (APh).

Material and methods

We have carried out in 12 lyrical singers a standard MPh and an APh with the program Dr. Speech Science 3.0.

Results

It was showed a significant difference with a p0,0005 in 14 of the 15 measures compared, and a p0,05 for the other one, being in general the results of the automatic test different from those of the manual in excess, with a correlation between the results obtained through both methods.

Conclusions

The APh obtained with the program Dr. Speech Science 3.0 is a faster and easier way to obtain the phonetogram than the one used to obtain the MPh, showing however big differences in excess compared with the ones of the MPh in all the usual phonetometric parameters.
