In this paper, an attempt to use syllables as alternative acoustic units to phones in text-to-speech tasks is presented. We proposed, examined and evaluated several options of syllable modelling within the scope of the statistical approach (using HMMs) to the acoustic unit inventory creation. To be able to synthesize an arbitrary text, the inventory has to be extended with triphones, resulting in a hybrid syllable/triphone inventory. First, we did not reflect the phonetic contexts of the syllables, because we supposed that the most of co-articulation is included inside syllables. Next, we also tried to model the context-dependent syllables. However, it is not viable to take each individual phone as a context. Therefore, each context was formed by a group of acoustically similar phones. Several listening tests were performed to rate the quality of the resulting synthetic speech.
