“…This work presents a G2P converter with stress determination for BP that is based on a set of rules described in [42]. The rules did not focus in any BP dialect.…”

“…The rules did not focus in any BP dialect. One advantage of rule-based G2P converters is that the lexical alignment is not necessary [42], which is a requirement of some approaches based on machine learning.…”

“…The code presented above describes the rule 8 applied for the determination of the stressed vowel [42] and can be explained as follows. The end of the word is indicated by the symbol #.…”
