Acoustic correlates of singleton vs. geminate nasals in Italian were investigated on the basis of acoustic analyses carried out on Italian disyllabic words. In the analysed words, the singleton vs. geminate consonant appeared in the symmetrical context of the three Italian vowels [a, i, u]. Time related, frequency related and energy related parameters were examined. Time parameters were all based on durational measurements performed within the consonant and surrounding vowels. Frequency parameters, such as formants, fundamental frequency and energy based parameters were computed at different sampling points all through the analysed words. Results showed that the durations of the consonant and pre-consonant vowel were significantly different in singleton vs. geminate words. Moreover, the ratio between the above durations was significantly related to gemination. These results were in agreement with previous studies on the gemination of Italian stops and fricatives. However, contrarily to what observed for stops and fricatives, nasal geminate consonants also exhibited a significantly larger energy than their singleton counterparts.

Abstract
Acoustic correlates of singleton vs. geminate nasals in Italian were investigated on the basis of acoustic analyses carried out on Italian disyllabic words. In the analysed words, the singleton vs. geminate consonant appeared in the symmetrical context of the three Italian vowels [a, i, u]. Time related, frequency related and energy related parameters were examined. Time parameters were all based on durational measurements performed within the consonant and surrounding vowels. Frequency parameters, such as formants, fundamental frequency and energy based parameters were computed at different sampling points all through the analysed words. Results showed that the durations of the consonant and pre-consonant vowel were significantly different in singleton vs. geminate words. Moreover, the ratio between the above durations was significantly related to gemination. These results were in agreement with previous studies on the gemination of Italian stops and fricatives. However, contrarily to what observed for stops and fricatives, nasal geminate consonants also exhibited a significantly larger energy than their singleton counterparts.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
