The objective of the present analysis is to present linguistic constraints on the phonetic realisation of lexical tone which are relevant for the choice of a speech synthesis development strategy for a specific type of tone language. The selected case is Thadou (Tibeto-Burman), which has lexical and morphosyntactic tone as well as phonetic tone displacement. The last two constraint types differ from those in more well-known tone languages such as Mandarin, and present problems for mainstream corpus-based speech synthesis techniques. Linguistic and phonetic models and a ‘microvoice’ for rule-based tone generation are developed.
