Improving Synthetic Speech Quality By Systematic Evaluation

Louis C.W. Pols

University of Amsterdam, The Netherlands

In the joint Dutch research program for developing a high-quality text-to-speech synthesis system, much emphasis is put on systematic speech quality evaluation. This is not just done to produce performance figures, but even more so to support the developers of the various linguistic and acoustic synthesis modules by indicating to them ways for improvement. This approach compares favourably with most other projects in which no diagnostic testing is done at all, or only once in the final phase in order to produce (incomparable) performance figures which do not lead to further improvements. The joint project is sponsored by SPIN (Dutch National Program for the Advancement of Information Technology).
