Statistical properties of the tongue movement during natural speech

The objective of this paper is to extract and understand the statistics of tongue movementand analyze the pattern of their movement in free speech.The data used here is the audio signals and sensor readings of the tongue movement offour native English speakers with American accent.Tools from signal processing and probability theory are used to characterize the timeseriescorresponding to the tongue movements. For each speech segment we will create afeature vector corresponding to the spectral properties of the movement. By pooling thesefeatures corresponding to each speech epoch, the principal components of the movementsof different subjects are extracted and studied for their similarity.The transition dynamics will be investigated by creating a transition matrix that woulddescribe the probability of the tongue to move from one location to another in freespeech. Such transition matrices corresponding to the four subjects will be compared fortheir statistical similarities.
