Abstract
The principal object of this invention is to provide a suitable control method for closing length with respect to phonemes (such as unvoiced plosive consonants) having a closing interval, and as a result an improved rule-based speech synthesis device is provided. A phoneme type judgement partjudges whether the phoneme in question is a vowel or consonant and, in the case of a consonant, judges whether or not it is a consonant that anteriorly has a closing interval. As a result, it operates a vowel length estimation partwhen it judges that the phoneme is a vowel and operates a consonant length estimation partwhen it judges that the phoneme is a consonant, and when it has judged that this phoneme anteriorly has a closing interval, it operates a closing length estimation part, whereby the respective time lengths are estimated. After that, the estimated time lengths are set by vowel length setting part, consonant length setting partand closing length setting part, respectively.
