Comments:

According to Canepari (2005) vowel sequences in words like "piú, chiedo, qua, buono" are pronounced as glide+vowel sequence, that is not as diphthongs. Canepari accepts only /ai/, /au/ ( "fai, pausa") as diphthongs. Other sequences he refers to as /Vw/, /Vj/, /wV/, /jV/. The description of Italian based on Bertinetto and Loporcaro (2005)is different with respect to treatment of diphthongs. The description here is based on the latter.

***

Jacques Koreman added geminate consonants in February 2021, because L1-L2map would not generate exercises in CALST for those if they are not defined as separate phonemes: CALST exercises are only generated for red cells. Example: Both Dutch and Italian have /p/, but Dutch does not have the geminate which Italian does have. If the geminate is not defined as a separate phoneme, Dutch learners would never get exercises for geminate sounds.
Deleted /j/ and /w/ which are considered part of a diphthong. Allowed /n l r/ in coda (con, il, per), but not /s/ which is analyzed as part of next onset (but see discussion of this in Canepari (1992) and Hall (1944) reference on wikipedia entry "Italian phonology), downloaded 13.01.2022). Geminates are marked as onset consonants under "View positions", but are of course part of coda and onset.

***

JK/PW: Geminates in Italian are marked for onset position. Italian allows geminates only across syllable boundaries, so they fill an onset position plus the previous coda position. They cannot occur at the beginning or end of a word (preceded/followed by a pause); this description does not take raddoppiamento fonosintattico into account).
