Statistical phonetic analysis of the Romanian language for speech recognition and synthesis tasks

This article provides a statistical phonetic analysis based on the largest Romanian text corpus collected so far for research purposes. Several types of phonetic events are analyzed: phones, diphones, triphones, and phone clusters based on the general classification of phones in the Romanian language. Some interesting conclusions are drawn, such as the fact that less than half the diphones cover 99% of the whole text. The article also discusses some usages of these phonetic statistics for spoken language technology tasks.
