LeTalker is the name of a Matlab GUI version of the three-mass model of vocal fold vibration originally described in: Story and Titze (1995). The specific implementation available here, however, is based directly on Titze and Story (2002) and Titze (2002). This allows for muscle activation levels to be specified as input parameters which are transformed to mechanical parameters of the lumped-element model. LeTalker includes both subglottal and supraglottal (vocal tract)systems. Vocal tract shapes can be chosen from the collection of area functions published in Story, Titze, and Hoffman (1996). The intent in making a simple version of the model public is for demonstration purposes and for researchers interested in programming this particular lumped-element model. Users are free to use the code as a starting point for model development or as a comparison to previously written code (just give credit where due). Essentially everything in the code has been published in the papers cited above.
