INTRODUCCIÓN: Definir valores de referencia para diagnóstico del habla a través de los formantes vocálicos
normalizados y no-normalizados del español colombiano. MÉTODOS: Estudio transversal con
inclusión población aleatoria por muestreo estratificado. 111 participantes 45 hombres, 66 mujeres.
Recolección de datos con frase vehicular para vocales sostenidas. Analisis No-Normalizado usando mediana
y media por genero y edad. Análisis Normalizado a través de Labov y Nearey. RESULTADOS: Los
valores de referencia encontrados son: (1) No-Normalizados: /a/ F1 867,03 Hz, F2 1435,85 Hz, /e/ F1
482,69 Hz, F2 2152,30 HZ; /i/ F1 330,48 Hz, F2 2400,11 Hz; /o/; F1 488,62 Hz, F2 984,22Hz; /u/ F1 368,93
Hz, F2 815,88 Hz; (2) Normalizción Labov: /a/ F1 1106,8 Hz, F2 1831,1 Hz, /e/ F1 616,5 Hz, F2 2755,4 Hz;
/i/ F1 422 Hz, F2 3072 Hz; /o/; F1 623,7 Hz, F2 1255,8 Hz; /u/ F1 471 Hz, F2 1047,7 Hz; (3) Normalización
Nearey /a/ F1 846 Hz, F2 1347 Hz, /e/ F1 467 Hz, F2 1954 Hz; /i/ F1 312 Hz, F2 2190 Hz; /o/; F1 463 Hz,
F2 940 Hz; /u/ F1 350 Hz, F2 759 Hz. ANÁLISIS Y DISCUSIÓN: El método de normalización que da cuenta
de la conformación acústica y articulatoria del español colombiano es el de Nearey con inclusión del
tercer formante para el cálculo del centroide S. CONCLUSIONES: La inclusión del tercer formante durante
la normalización de Nearey permite ajustar los valores del Espacio Vocálico a la configuración acústica
y articulatoria del español.
