This paper presents, on one side, a subjective assessment of 72 teachers on their vocal characteristics from a summary of the Voice Handicap Index (VHI) (Jacobson et alii, 1997), a rigorously validated questionnaire. More precisely, we used the short version, also validated, VHI-10 (Rosen et alii, 2004). And, on the other side, an objective analysis of different parameters (jitter, shimmer, harmonic to noise ratio, durations, average F0, etc.) was done. The participants are teachers in Madrid and Barcelona, from pre-school to high school levels. This paper, a part of a most wide work, presents the results obtained in a school week at the end of the first academic quarter, from samples taken in Monday and Friday, considering the objective and subjective above variables.
Keywords: vocal effort; subjective and objective fonation assessment; acoustic analysis; voice quality; professional voice use; teaching and phonation.
