SINTETIZZATORE DI PAROLA, BASATO SU FONEMI, REALIZZATO SOTTO FORMA DI CIRCUITO INTEGRATO. |
摘要 |
A phoneme-based speech synthesizer that is particularly adapted for implementation on a single integrated circuit chip includes a vocal tract model comprised of a fixed resonant filter and a plurality of tunable resonant filters whose resonant frequencies are controlled in accordance with the values of certain control parameters. A digital transition circuit is included which gradually transitions the values of the vocal tract control parameters as they change from phoneme to phoneme by iteratively adding to the current values a predetermined percentage of the difference between the current and target values. The vocal tract model is implemented utilizing a capacitive switching technique which eliminates the need for large valued components to achieve the relatively low frequencies of human speech. A glottal source generator is adapted digitally to generate a glottal pulse signal in a manner which readily permits the glottal pulse to be spectrally shaped in any desired configuration. <IMAGE> |
