7. Top row: left, vocal tract contours obtained during the production of [sal]; right, diagrams depicting differences found, over time, for all realisations of /al5/. Bottom row: differences computed along the production of /il/ and /ul/ using the first frame of each as reference. 4 Conclusions Considering the three goals set for our work, these have been successfully attained. The segmentation method provided very good results with only some minor issues, resulting from the noisy nature of the images.

The results regarding syllable position effects and coarticulation of /l/ with adjacent vowels are in line with previous findings. Keywords: laterals, quantitative analysis, RT-MRI. 1 Introduction Lateral consonants are articulatorily complex and variable sounds. In several languages, the /l/ is associated with two canonical allophones (light /l/ in syllable onset, and dark /l/ in coda position). The most important articulatory distinction between them is a greater tongue dorsum retraction in the dark /l/ than in the light variety [9,20].

These three information streams are parameterized through log-f0, MCEP coefficients and maximum voiced frequency (MVF), respectively. Fundamental frequency estimation is based on autocorrelation maximization with dynamic programming smoothing followed by a refinement based on quasi-harmonic analysis. MVF is estimated according to the sinusoidal likeness of the spectral peaks near the harmonic positions. Since these two analysis modules do not play a relevant role in this study, we omit further details about them (interested readers should refer to [18]) and focus on spectral envelope analysis.
