PURPOSE:To eliminate monotonicity of rule-synthesize voice and to synthesize a rule voice having high comprehensiveness by controlling the addition of a prominence in accordance with various elements such as speed and contents of uttering. CONSTITUTION:This synthesizer is provided with a text input means which inputs a text, a morpheme processing section 1a which divides the inputted text into morphemes, a dictionary 1b which stores a dictionary information that is referred to by the section 1a, a reading accent processing section 1d which adds reading and accents and a synthesis processing section 3 which synthesizes voice. Moreover, the synthesizer is provided with an uttering speed setting section 6 which sets the uttering speed of a synthesized voice and a prominence adding section 1e which adds the presence or the absence of a prominence (emphasis on a particle) and based on the uttering speed selected by an uttering speed selection means, the section 1e decides the presence or the absence of a prominence. When the uttering speed is slow, the frequency of appearance of the prominence of accessory word is made higher. If the uttering speed is fast, the frequency of appearance of the prominence is made lower. Thus, a fundamental frequency pattern, which expresses the prominence, is selected so as to express a natural prominence by a synthesized voice. |
