Abstract
In this paper, it is our aim to define a set of objective acoustic criteria, based on subjective listeners assessment of talent voices, that can help to
rate the voice font quality, bearing in mind the development of Text-to-Speech
systems (hereafter TTS). The voice talent selection process is seldom discussed
in scientific papers, since academic community is obviously more concerned
with synthetic voice evaluation than with modal voice talent assessment. However, the choice of a voice that will be used in TTS systems is definitely of extreme importance. In this work, we describe the selection process of the Brazilian Portuguese voice talent, based on socio and linguistic criteria and supported
by subjective and objective tests and measurements of modal voice quality. Relationship between subjective and objective parameters is presented and discussed. A subjective test comparing natural and resynthesized voices was also
conducted and its results are discussed
