Resumo:
Due to its characteristics and applications Voice Response Systems (VRS) have grown in
importance in the past. SRV can be classified as Stored Voice Systems (SVS) and Text-to-Speech
Conversion Systems (TSCS).
SVS and TSCS pose a major difference: the former originates speech from words
previously recorded and stored. The latter employs a technique to produce voice by
concatenation of acoustic units, allowing the implementation of the entire set of words of a
language. TSCS present two main modules: linguistic processing that characterizes an idiom
and a signal processing unit responsible for sound synthesis.
The main objective of this work is to formulate a TSCS structure, considering the
Portuguese language. This structure must be able to reproduce a natural and comprehensible
speech for the Portuguese language spoke in Brazil.
