MATLAB Files main.m – The wrapper function, calls the remaining MATLAB functions after taking in the user’s voice and outputs the identity of the speaker. vocalModel.m – Creates a model of the vocal system. databaseCreationScript.m – Stores the vowel sounds of the entire group. graphFormant.m – Plots the frequency response of the formants on a logarithmic scale. fastconv.m – Calculates the linear convolution of two input signals. zerovect.m – Removes DC offset and microphone turn on effect. formantaverages.m – Stores vowel models and formant ranges in the database. getFormantData.m – Gets formant frequencies and model for one speaker and one vowel. newenvdetect.m – Detects the start and end points of the envelope. formantfind.m – Finds the formant frequencies and magnitudes for one vocal model.
