Seminar at Speech, Music and Hearing:

Articulatory strategies. How different can they be?

Gopal Ananthakrishnan


Comparing the articulations made by two subjects, one male and one female can be quite intriguing. Based on the MRI data collected at INP-Grenoble for 83 articulations of French phonemes by two subjects, it can be seen that there are a lot of variations in the strategies made by different people. Using PARAFAC a 2-way variance analysis tool, a single articulatory model can be used for explaining the different modes of variations in articulations and subjects. However, these models need almost 150% more parameters in order to get the same error in reconstruction on the true data as compared to individual models. When trying to predict unknown articulations of one subject from the known articulations of the other subject, the model fails and the error increases with increased number of parameters.
