The Vowel Worm: Real-time Mapping and Visualisation of Sung Vowels in Music
نویسندگان
چکیده
This paper presents an approach to predicting vowel quality in vocal music performances, based on common acoustic features (mainly MFCCs). Rather than performing classification, we use linear regression to project spoken or sung vowels into a continuous articulatory space: the IPA Vowel Chart. We introduce a real-time on-line visualisation tool, the Vowel Worm, which builds upon the resulting models and displays the evolution of sung vowels over time in an intuitive manner. The concepts presented in this work can be used for artistic purposes and music teaching.

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 کاملThe Study of Vowel Space and Formant Structure in Mazani Language
Objective: One of the parameters showing the correct phonetic and phonological development is the correct and clear articulation of vowels is achieved by changing the shape of vocal cords through altering the height and position of the tongue and the movement of the lips and jaw. The tongue’s height and position are the basis of the production and difference of vowels. In other words, the raw s...
متن کاملStudy and Comparison of Formant Characteristics of Persian Vowels in 4-7-year-old Children Using Cochlear Implants and Those Using Hearing Aids
Background and Objective: One of the most important physical properties of vowels is their formant structure. One of the most obvious speech errors in hearing-impaired children is vowel errors. The present study aimed to determine and compare the formant structure of Persian vowels in deaf and cochlear implant children in the age range of 4-7 years. Materials and Methods: This descriptive-anal...
متن کاملEarly integration of vowel and pitch processing: a mismatch negativity study.
OBJECTIVE Several studies have explored the processing specificity of music and speech, but only a few have addressed the processing autonomy of their fundamental components: pitch and phonemes. Here, we examined the additivity of the mismatch negativity (MMN) indexing the early interactions between vowels and pitch when sung. METHODS Event-related potentials (ERPs) were recorded while partic...

The main goal of this study is to determine the auditory feedback effects in improvement of speech production process in prelingual totally deaf children who used cochlear implant prosthesis. For this reason, we recorded speech of four prelingual cochlear implant children pre and post of operation. Then we extract some static features of vowels-such as fundamental frequency, formant frequencies...
