ABSTRACT:
The invention relates to a method and an arrangement for speech synthesis and provides an automatic mechanism for simulating human speech. The method provides a number of control parameters for controlling a speech synthesis device. The invention solves the problem of coarticulation by using an interpolation mechanism. The control parameters are stored in a matrix or a sequence list for each polyphone. The behaviour of the respective parameter with time is defined around each phoneme boundary and polyphones are joined by forming a weighted mean value of the curves which are defined by their two associated matrices/sequences list. The invention also provides an arrangement for carrying out the method.
