Resumen:
In this paper an initial acoustic analysis of the five Spanish vowels in emotional speech is given, for both Spanish as spoken in Spain and Spanish as spoken in Mexico. More precisely, two emotional speech databases, which were recorded by professional actors from both Spain and Mexico, were processed to obtain information about the vowels concerning their durations, fundamental frequencies and the first two formant frequencies, as a function of the emotion type. This quantitative information is analyzed to provide some conclusions, such as the possible correlations with the level of arousal of the speaker’s emotional state and the similarities and differences between speakers in Spain and Mexico.
