This paper identifies the pertinent acoustic segments to be applied in a Brazilian Portuguese text-to-speech synthesis system. In order to obtain a normalized length measurement, the vocalic segments are analyzed with respect to the lexical and phrasal stresses, besides its syllable positions in the initial and at the end of the utterances. Results show that these features are relevant factors to establish the acoustic units' duration mean.
