Abstract

Det er beskrevet en talebehandlingsanordning, der forutsigelsesutgang for å finne forutsigelsesverdier for talen som har høy lydkvalitet, blir trukket ut fra den syntetiserte lyd som er fremkommet ved å føre lineære forutsigelseskoeffisienter og restsignaler, frembragt fra en forhåndsstilt kode, til et talesyntesefilter der talen med høy lydkvalitet har høyere lydkvalitet enn den syntetiserte lyd, og der forutsigelsesuttakene blir benyttet sammen med forhåndsstihe uttakskoefEsienter for å utføre forhåndsstilte forutsigelsesberegninger for å finne forutsigelsesverdiene for talen som har høy lydkvalitet. Lyden som har høy lydkvalitet har høyere lydkvalitet enn den syntetiserte lyd. Anordningen omfatter en enhet (45) til uttrekning av forutsigelsesuttak fra den syntetiserte lyd, der forutsigelsesuttakene benyttes til forutsigelse av talen som har høy kvalitet, som måltale, for hvilken forutsigelsesverdi og en enhet (46) for uttrekning av klasseuttak, benyttet til klassifisering av måltalen i en av et flertall klasser fra den ovenstående kode. Anordningen omfatter også en k]assifiseringsenhet(47) for å finne klassen for måltalen basert på klasseuttakene, uthentningsenhet og uthéntning av uttakskoefEsienter som er knyttet til klassen for måltalen fra blant uttakskoefifsientene som er funnet ved opplæring fra klasse til klasse, og enforutsigelsesenhet (49) for å finne forutsigelsesverdiene for måltalen ved bruk av forutsigelsesuttak og uttakskoefifsientene som er knyttet til klassen for måltalen.
