The aim of this paper is perform the synthesis of sung Spanish vowels considering the soprano vocal category of lyrical singers, including variation of sustained pitches with vibrato and tremolo effects, considering sounds from Spanish language. The Fant source-filter theory is used to model the production of the sung vowels: the source is based on the Rosenberg glottal pulse model and the filter (the vocal tract) is composed by an all-pole filter model with formant frequencies and bandwidths from the vowels of the Spanish language, obtained through experimental voice signals from two soprano singers. All the sounds synthesized are available to be accessed and they were submitted to a group of listeners which gave a very good evaluation with respect to the intelligibility and naturalness of the sounds.

女高音抒情歌唱中西班牙元音的合成


本文的目的是考虑抒情歌手的女高音声乐类别，对所唱的西班牙语元音进行合成，包括考虑西班牙语声音的颤音和颤音效果的持续音高变化。 Fant 源滤波器理论用于对所唱元音的产生进行建模：源基于 Rosenberg 声门脉冲模型，滤波器（声道）由全极点滤波器模型组成，其共振峰频率和带宽为西班牙语的元音，通过两位女高音歌手的实验语音信号获得。所有合成的声音都可供访问，并将它们提交给一组听众，他们对声音的清晰度和自然度给出了非常好的评价。
