Acoustic-phonetic properties of smiling revised - Measurements on a natural video corpus
نویسندگان
چکیده
Smiling while talking can be perceived not only visually but also audibly. Several acoustic-phonetic properties have been found to cue smiling in the acoustic signal. The aim of this study was to validate properties associated with smiled speech using a natural video corpus. The realisations of monophthongs of the same words spoken with and without a visible smile were compared. The results show a significant increase of intensity (for all words), of F2 (for words with the round vowel /o:/) and of F0 (for all words except the backchannel marker ja) in the smiled condition.

Acoustic Analysis of Persian EFL Learners' Pronunciation of English Vowels
This paper reports the results of an experimental study on non-native production of English vowels. Two groups of Persian EFL learners varying in language proficiency were tested on their ability to produce the nine plain vowels of American English. Vowel production accuracy was assessed by means of acoustic measurements. Ladefoged and Maddison’s (1996) F1 F2 measurements for American English v...
متن کاملPost-aspiration in standard Italian: some first cross-regional acoustic evidence
Voiceless geminate stops in Italian are typically described as unaspirated in all positions (e.g. [1, 2]). However, recent acoustic phonetic analysis of part of a corpus of standard Italian speech data has shown that the geminate voiceless stops /pp tt kk/ are frequently realized with both preaspiration i.e. [p: t: k:] (cf. [3]) and post-aspiration. This paper focuses on the latter phenomenon, ...
متن کاملAcoustic Properties of Dutch Steady-state Vowels: Contextual Effects and a Comparison with Previous Studies
Recent vowel corpora show that there are often clear acoustic differences between vowels produced in different phonetic contexts. We expand on a recent corpus of Northern Standard Dutch (NSD) vowels by including a variety of consonantal contexts. Our results show that there are very clear contextual effects on the spectral and temporal properties of NSD vowels. The most striking effect is the a...
متن کاملHeterogeneous acoustic measurements and multiple classifiers for speech recognition
The acoustic-phonetic modeling component of most current speech recognition systems calculates a small set of homogeneous frame-based measurements at a single, fixed time-frequency resolution. This thesis presents evidence indicating that recognition performance can be significantly improved through a contrasting approach using more detailed and more diverse acoustic measurements, which we refe...
متن کاملItalian Geminates under Speech Rat Kinematic , Acoustic , and Barbara
Italian geminate consonants have been studied as for both their phonetic characteristics and their phonological status. As for the phonetic aspects, though, few works focus on kinematic data. This study relates on both acoustic and kinematic material, as well as on perception data, in order to get evidence on the phonological status of geminate consonants. A read speech corpus was collected and...
