Second ESCA/IEEE Workshop on Speech Synthesis
September 12-15, 1994
In this paper we will discuss development of rule-based female speech synthesis, focusing on segmental level improvements. A higher degree of naturalness is achieved by the inclusion of voice source variations and more complex articulation modelling. Source, formant and pole/zero parameter data generated by inverse filtering have been interpreted and incorporated into the female text-to-speech rule system. In particular, the quality of consonants with complex articulations and vowel-consonant transitions is enhanced. A diagnostic intelligibility test was performed on the preliminary rule system. Results are discussed in terms of error sources and possible solutions. On-going work includes fine-tuning of LF-source and pole/zero parameter control, based on these results.
