Vocal tract shape estimation is essential for development of speech training aids for hearing impaired. Speech therapists have concluded from their research that if speech disorders are detected at an early stage then the rectification of those becomes faster and to a great accuracy. The paper presents the notability of variation of vocal tract shape and formant frequency with its adjacent ratios, for the Indian Telugu speakers for the vowels of the Telugu language. We have estimated the vocal tract shape of the Indian Telugu speakers. For the estimation we have incorporated Autoregressive Model and the same for the formant frequency. These samples are recorded for 20 individual iterations for both male and females. The vocal tract shape estimation and formant frequency estimation are done on the Matlab platform. These outcomes are used for observation of vocal tract infection among the speech disorder patients; it can be adopted for the user authentication system by considering it as a vocal tract signature.
