Abstract

A text-to-speech method for use in a plurality of languages, said method comprising: inputting text in a selected language; dividing said inputted text into a sequence of acoustic units; converting said sequence of acoustic units to a sequence of speech vectors using an acoustic model, wherein said model has a plurality of model parameters describing probability distributions which relate an acoustic unit to a speech vector; and outputting said sequence of speech vectors as audio in said selected language, wherein a parameter of a predetermined type of each probability distribution in said selected language is expressed as a weighted sum of language independent parameters of the same type, and wherein the weighting used is language dependent, such that converting said sequence of acoustic units to a sequence of speech vectors comprises retrieving the language dependent weights for said selected language.
