Speech synthesis-by-rule from unlimited text requires much phonetic knowledge. By trial-and-error, as well as by systematic diagnostic evaluation, system deficits can be identified and subsequently improved in the best possible way. Another approach is to tune the rules in accordance with global and/or specific facts derived from analyzing natural speech, accessible via a speech database. These two approaches may well be complementary, but they can also be in (partial) conflict. This is related to the fact that, frequently, rules do not just describe phonetic and linguistic facts but also serve to compensate for certain system artefacts or limitations, such as fixed-duration stressed diphones as building blocks, synchronous formant transitions, or an all-pole source-filter model. Ideally one would like to see more interaction between gaining phonetic knowledge and improving synthetic speech quality.
