چکیده

A method has been developed for three-dimensional reconstruction of the vocal tract shape and for the calculation of area function from magnetic resonance imaging (MRI). MR images were acquired and analyzed for 6 German long vowels uttered by one subject. The resulting vocal tract area functions are the basis for the calculation of formant frequencies. Conformity with acoustically measured formant frequencies can be stated. A principal component analysis applied to the vocalic area functions derived from these articulatory data indicates that its variance can be described by few main factors.

Toward Automatic Vocal Tract Area Function Estimation from Accelerated Three-dimensional Magnetic Resonance Imaging

Vocal tract area function estimation from three-dimensional (3D) volumetric dataset often involves complex and manual procedures such as oblique slice cutting and image segmentation. We introduce a semi-automatic method for estimating vocal tract area function from 3D Magnetic Resonance Imaging (MRI) datasets. The method was implemented on a custom MATLAB graphical user interface and computes t...

Estimating the vocal-tract area function and the derivative of the glottal wave from a speech signal

We present a new method for estimating the vocal-tract area functions from speech signals. First, we point out and correct a long-standing sign error in some literature related to the derivation of the acoustic reflection coefficients of the vocal tract from a speech signal. Next, to eliminate the influence of the glottal wave on the estimation of the vocal-tract filter, we estimate the vocal-t...

Vocal tract area functions from magnetic resonance imaging.

There have been considerable research efforts in the area of vocal tract modeling but there is still a small body of information regarding direct 3-D measurements of the vocal tract shape. The purpose of this study was to acquire, using magnetic resonance imaging (MRI), an inventory of speaker-specific, three-dimensional, vocal tract air space shapes that correspond to a particular set of vowel...

Comparison of Fricative Vocal Tract Transfer Functions Derived using Two Different Segmentation Techniques

The acoustic and articulatory properties of fricative speech sounds are being studied using magnetic resonance imaging (MRI) and acoustic recordings from a single subject. Area functions were derived from a complete set of axial and coronal MR slices using two different methods: the Mermelstein technique and the Blum transform. Area functions derived from the two techniques were shown to differ...

Synthesizing static vowels and dynamic sounds using a 3D vocal tract model

The KTH 3D Vocal Tract project aims at multimodal synthesis, producing both visual and acoustic output from an articulatory model. The intra-oral visual synthesis has been developped over the last couple of years combing measurements from Magnetic Resonance Imaging, Electromagnetic articulography and Electropalatography. This paper presents the first acoustic evaluation of the model. Nine stati...
