In this paper, it is our aim to define a set of objective acoustic criteria, based on subjective listeners’ assessment of talent voices, which can help to automatically rate the voice font quality, bearing in mind the objective definition of voice preference for the Portuguese language. For this purpose a multilingual and multispeaker database was recorded and a set of subjective and objective information was obtained. The analysis of the data provided new results that can be successfully used to define the quality of a given voice. The achieved results for Portuguese were compared with those obtained for other language with objective of identifying common properties, which was statistically confirmed with a within a 90% confidence interval.
