Abstract
This paper aims to synthesize the sung Spanish vowels with covering considering the soprano vocal category of lyrical singers, including variation of sustained pitches with vibrato effect. The Fant source-filter theory is used to model the production of the sustained vowels. The source is based on the Rosenberg glottal pulse model and filter (the vocal tract) is composed by an all-pole filter model with formant frequencies and bandwidths from the vowels of Spanish language. All the sounds synthesized are available to be accessed and they were submitted to a group of listeners and they received a very good evaluation with respect to their intelligibility and naturalness.
