The GEMMA speech database: VCV and VCCV words for the acoustic analysis of consonants and lexical gemination in Italian

The GEMMA database consists in recordings of disyllabic words: vowel–consonant–vowel (VCV) for nongeminate cases and vowel–consonant–consonant–vowel (VCCV) for geminate cases. The consonants in the words are stops, affricates, fricatives, nasals and liquids. Six native adult speakers of Standard Italian, three female and three male, were recorded. The database also includes recordings for glides (/j/,/w/). The vowels in the words are /a, i, u/; words are symmetric with respect to vowel. The dataset also includes measurements of duration parameters for all of those consonants that can be either singletons or geminates, used in the research papers: M.-G. Di Benedetto and L.
