Abstract
A method for selecting acoustic units each of which contains a natural speech signal and symbolic parameters involves a stage (4) for determining at least one target symbolic unit sequence; a stage (5) for determining a contextual acoustic model sequence corresponding to the target sequence; a stage (6) for determining an acoustic template on the basis of the contextual acoustic model sequence and a stage (7) for selecting the acoustic unit sequence according to the acoustic template applied to the target symbolic unit sequence. The invention is used for voice synthesis.

23. A process for the selection of acoustic units corresponding to acoustic productions of symbolic units of a phonological nature, the said acoustic units each comprising a natural speech signal and symbolic parameters representing their acoustic characteristics, the said process comprising:
-
determining at least one target sequence of symbolic units determining a sequence of contextual acoustic models corresponding to the said target sequence, determining an acoustic template from the said sequence of contextual acoustic models; and
selecting a sequence of acoustic units on the basis of the said acoustic template applied to the said target sequence of symbolic units. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
