This paper describes the vowels characteristics of three languages of Nagaland namely Nagamese, Ao and Lotha. For this study, nucleus vowel duration, formant structure (1 st and 2 nd formant i.e. F1 and F2) and intensity of vowels are investigated and analyzed for these languages. This paper includes the nasal context for different vowels and tries to examine its importance in different languag...

We studied mutual influences between native and non-native vowel production during learning, i.e., before and after short-term visual articulatory feedback training with non-native sounds. Monolingual French speakers were trained to produce two non-native vowels: the Danish /ɔ/, which is similar to the French /o/, and the Russian /ɨ/, which is dissimilar from French vowels. We examined relation...

The usefulness of dynamic formant properties for speaker discrimination was demonstrated on English, mostly exploiting long vowels or diphthongs, characterized both by actual measures along the formant tracks and coefficients from polynomial regression on these tracks. This study applies this paradigm to Czech, using less tightly controlled (more forensically realistic) material and taking into...

The present study examines two methods for learning and modeling vowel harmony from text corpora. The first uses Expectation Maximization with Hidden Markov Models to find the most probable HMM for a training corpus. The second uses pointwise Mutual Information between distant vowels in a Boltzmann distribution, along with the Minimal Description Length principle to find and model vowel harmony...

The formant frequencies of Malaysian Malay children have not been well studied. This article investigates the first four formant frequencies of sustained vowels in 360 Malay children aged between 7 and 12 years using acoustical analysis. Generally, Malay female children had higher formant frequencies than those of their male counterparts. However, no significant differences in all four formant ...

This study compares the acoustic realisation of /iː yː ʉː uː/ in three varieties of Swedish: Central Swedish, Estonian Swedish, and Finland Swedish. Vowel tokens were extracted from isolated words produced by six elderly female speakers from each variety. Trajectories of the first three formants were modelled with discrete cosine transform (DCT) coefficients, enabling the comparison of the form...

This study examines cross-linguistic variation in the location of shared vowels in the vowel space across five languages (Cantonese, American English, Greek, Japanese, and Korean) and three age groups (2-year-olds, 5-year-olds, and adults). The vowels /a/, /i/, and /u/ were elicited in familiar words using a word repetition task. The productions of target words were recorded and transcribed by ...
