Abstract :
A method for reducing the characteristic buzz from LPC synthetic speech is presented. The method consists of the use of an non-impulse source for exciting the LPC synthesizer during voiced sounds. One novel feature is that the temporal parameters of the source are kept in fixed proportion to the pitch period. An extensive perceptual experiment has shown that the resulting quality of the synthesis is significantly preferred over the quality of the standard LPC synthesis.
