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)
We compare numerically computed resonances of the human vocal tract with formants that have been extracted from speech during vowel pronunciation. The geometry of the vocal tract has been obtained by MRI from a male subject, and the corresponding speech has been recorded simultaneously. The resonances are computed by solving the Helmholtz partial(More)
Many languages exploit suprasegmental devices in signaling word meaning. Tone languages exploit fundamental frequency whereas quantity languages rely on segmental durations to distinguish otherwise similar words. Traditionally, duration and tone have been taken as mutually exclusive. However, some evidence suggests that, in addition to durational cues,(More)
Discrete phonological phenomena form our conscious experience of language: continuous changes in pitch appear as distinct tones to the speakers of tone languages, whereas the speakers of quantity languages experience duration categorically. The categorical nature of our linguistic experience is directly reflected in the traditionally clear-cut linguistic(More)
A procedure for the vectorisation and feature extraction of the human vocal tract is proposed. The raw data is obtained by high resolution 3D MRI. Because the amount of manual work in the data processing has been minimised, large datasets can be treated. The vectorised data can be used for both numerical as well as physical modelling of the vocal tract(More)
Speech in noise, or Lombard speech, is characterized by increased intensity and higher fundamental frequency as well as lengthened segmental durations as speakers try to maintain a beneficial signal-to-noise ratio to fill both communicative and self-monitoring requirements. The phenomenon has been studied with regard to different noise types and different(More)
We describe an arrangement for simultaneous recording of speech and geometry of vocal tract in patients undergoing surgery involving this area. Experimental design is considered from an articulatory phonetic point of view. The speech and noise signals are recorded with an acoustic-electrical arrangement. The vocal tract is simultaneously imaged with MRI. A(More)
The complex auditory brainstem response (cABR) can reflect language-based plasticity in subcortical stages of auditory processing. It is sensitive to differences between language groups as well as stimulus properties, e.g. intensity or frequency. It is also sensitive to the synchronicity of the neural population stimulated by sound, which results in(More)
A state-of-the-art 1D acoustic synthesizer has been previously developed, and coupled to speaker-specific biomechanical models of oropharynx in ArtiSynth. As expected, the formant frequencies of the synthesized vowel sounds were shown to be different from those of the recorded audio. Such discrepancy was hypothesized to be due to the simplified geometry of(More)
