This dataset is collected from the University of Tartu Phonetic Corpus of Estonian Spontaneous Speech. The dataset consists of words with CVCV and CVCCV structure and it has been collected for studying Estonian Quantity. The data set was collected for the paper:

Lippus, P., Asu, E. L., Teras, P., & Tuisk, T. (2013). Quantity-related variation of duration, pitch and vowel quality in spontaneous Estonian. Journal of Phonetics, 41(1), 17–28. https://doi.org/10.1016/j.wocn.2012.09.005
