SUMMARY:Speech prosody: from language characterization to paralinguistic us
 e
DESCRIPTION:Prosody plays an important role in spoken language\, encoding b
 oth linguistic and paralinguistic information. In this talk I will present
  two studies that touch upon each of these aspects. First\, I will show ho
 w long-term information from the speech signal\, captured by i-vectors\, c
 an be employed for automatic language characterization. 24 languages\, spa
 nning several families/sub-families\, were considered for this study and t
 heir centroid i-vectors were computed using one hour of recordings from ea
 ch language. The centroids were then correlated with typological features\
 , revealing that they relate to syntactic information. Based on these find
 ings\, a simple syntactic feature prediction system was proposed\, obtaini
 ng a 87% accuracy in a leave-one-out evaluation setting. Second\, I will i
 nvestigate the usefulness of prosodic information for the automatic detect
 ion of one of the most often found paralinguistic phenomenon in conversati
 on\, laughter. Employing features shown previously to discriminate between
  laughter and speech\, a syllable-based laughter detection system was put 
 forward. It obtained similar or higher performance to other detection syst
 ems\, that use more generic features. It also revealed that features relat
 ed to voice quality and rhythm characteristics are more discriminative tha
 n commonly-used features\, such as speech intensity or fundamental frequen
 cy.
