The development of a new vowel category was studied by measuring both automatic mismatch negativity and conscious behavioural target discrimination. Three groups, nai;ve Finns, advanced Finnish students of English, and native speakers of English, were presented with one pair of Finnish and three pairs of English synthetic vowels. The aim was to determine(More)
This article describes an arrangement for simultaneous recording of speech and the geometry of vocal tract. Experimental design is considered from the phonetics point of view. The speech signal is recorded with an acoustic-electrical arrangement and the vocal tract with MRI. Finally, data from pilot measurements on vowels is presented, and its quality is(More)
This study investigated whether speaking a foreign language affects the fundamental frequency (F0) of speech in 16 native Finnish and 14 native English subjects reading a text in Finnish and in English. The speech samples were analyzed for the mean and range of F0. Speaking a foreign language caused a change in F0 for the Finnish subjects, while the result(More)
Two experiments were conducted to determine whether vowel familiarity affects automatic and conscious vowel discrimination. Familiar (Finnish) and unfamiliar (Komi) vowels were presented to Finnish subjects. The good representatives of Finnish and Komi mid vowels were grouped into three pairs: front /e- epsilon /, central /ø-oe/, and back /o-o/. The(More)
Neurofibromatosis 1 (NF1) is a neurocutaneous-skeletal disorder often accompanied with varying degrees of cognitive and motor problems that potentially affect speech and language. While previous studies have shown that NF1 may be associated with a variety of deviations in the patients' speech, they have not investigated the characteristics in phonetic(More)
PURPOSE The effects of orthognathic surgery on the phonetic quality of speech were studied by analyzing the main acoustic features of vowel sounds. PATIENTS AND METHODS Five men with dentofacial deformities undergoing surgical operation for correction of malocclusion were enrolled in the study. The speech material consisted of 8 vowels in sentence(More)
OBJECTIVE The effects of the genioglossal muscle advancement on phonetic quality of speech were studied analyzing the acoustic features of vowel sounds. STUDY DESIGN AND SETTING The study group consisted of 5 men suffering from partial upper airway obstruction during sleep. To prevent tongue base collapse, genioglossal muscle advancement was made with(More)
PURPOSE The effects of lingual nerve impairment on the phonetic quality of diphthongs were studied by analyzing changes in their main acoustic features when anesthetic was injected into the lingual nerve to partly block the normal neural feedback mechanisms in speech. PATIENTS AND METHODS The speech material consisted of 8 diphthongs in word context(More)
The present study examined whether early exposure in language immersion would result in better pre-attentive discrimination of non-native speech sound contrasts. Mismatch negativity (MMN) responses were measured from two groups of Finnish children. The Monolingual group had no prior exposure to other languages than the native one, while the Immersion group(More)
We present anatomic and acoustic data from a pilot study on the Finnish vowels [A, e, i, o, u, y, ae, ø]. The data were acquired simultaneously with 3D magnetic resonance imaging (MRI) and a custom built sound recording system. The data consist of a single static repetition of each vowel with constant f 0. The imaging sequence was 7.6 s long and had an(More)
