Syllable lengths in Russian, Bulgarian, Old Church Slavonic and Slovene

This paper presents empirical syllable length data (with "syllable length" being based on the number of phonemes) from Slovene, modern Bulgarian, Old Church Slavonic (= Old Bulgarian) and modern Russian. The data analysed give evidence of the following adequate models: Hyperpoisson in Old Church Slavonic, modern Bulgarian and Slovene and Conway-Maxwell-Poisson or Morse in modern Russian.
