合成音声の母音部、子音部ともに一定の割合で、継続時
間が変化するものであった。The conventional analysis and synthesis method for controlling speech rate is as follows:
The duration of both the vowel and consonant parts of the synthesized speech changed at a constant rate.
しかし、人間が発話速度を変化させる場合、子音部の継
続時間の変化の割合よりも、母音部の継続時間の変化の
割合のほうが大きいのが通常であり、人間の発話速度に
そぐわないものであった。However, when humans change their speech rate, the rate of change in the duration of the vowel part is usually greater than the rate of change in the duration of the consonant part, which does not match the rate of speech of humans. Ta.

り、合成音声の発話速度を変化させるものである。An object of the present invention is to make the speech rate variable in a speech synthesis device that synthesizes arbitrary words1. [Summary of the Invention] In a speech synthesis device that synthesizes arbitrary words, the user , it is often desired that the synthesized sounds be uttered as slowly as possible until the user gets used to the synthesized sounds, and as quickly as possible after getting used to the synthesized sounds. Therefore, the present invention provides a speech synthesis device that synthesizes arbitrary words by combining consonant and vowel part chains, by changing the phoneme duration of the consonant part and the phoneme duration of the vowel part at different rates. This changes the speaking speed of synthesized speech.

A rule section 6 that reads rule parameters corresponding to phonetic symbols from the rule parameter file 7. Reads the phoneme chain corresponding to the phoneme symbol from the phoneme chain file 8,
Phonological combination unit 4 that performs combination processing. Speech synthesis section 51 that synthesizes speech from acoustic parameters.Speech output section 6 that outputs synthesized speech. It is composed of a control section 9 that controls all of these.
