and a dictionnary of 14969 words with aligned phones

Each .wav file (sampled at 22050Hz) corresponds to one entire chapter. The format of the filenames is:{author's acronym}_{book's acronym}_{reader's acronym}_{volume's number}_{chapter's number}

The IT.csv file gives text (or sometimes, phones) and signal alignments for utterances in 4 fields separated by '|': {filename}|{start_ms}|{end_ms}|{text or phonetic content}. Most utterances are separated by at least a pause of 400ms (exceptionally less when phonation exceeds 11s). The intervals [start_ms:end_ms] comprise leading and trailing silences of 130ms (since wavs are entire chapters, these silences are "true" ambient silences).

When phonetic alignment has been performed, 1 additional field has been added: {aligned phones}. Each input character or phone has a corresponding aligned phone. Note that all aligned utterances start and end with an aligned silence of 130ms. The set of aligned phones comprises:



The set of input phones

The silence: '__'

The symbol '_' for silent characters, e.g. "occhi" is aligned with 'o^1 k: _ _ i'


Text is in UTF8. '«»','—', '~','""','()','[]' are respectively used for speaking quotes, turn switches, three dots, quoted expression, aside quotes, notes. Because of rare occurrences, 'ö' has been transcribed as 'oe'. Paragraphs (two consecutive carriage returns in the original text) are cued by a special character '§'. It usually ends an utterance but could be used within an utterance if its associated pause is too short.

Part of text under clear emphasis is surrounded by "#"

When available, phonetic content is given per word in curly brackets '{}'. We use 39 phonetic symbols:



oral vowels: a (fa), e (ve), e^ (ed), i (riz), u (tu), o (uno), o^ (con)

loan vowels & diphtongs: a&i and x^ (timer),

semi-vowels: h (ghetto.), w (quel), j (vaj)

consonants: p (vespa), t (tu), k (calde), b (buon), d (disse), g (grazie), f (fame), s (sauna) , s^ (scia), v (verde), z (rosa), z^ (judo), r (rizo), l (letto), l^ (egli), m (mapo), n (nuda), n~ (pugni)

long/double consonants are suffxed by ":", e.g.  p: (zuppa)

primary stress if any is noted "1" and appended to the vowel, e.g. a1 g a p e (agape)
