1. A method for automatic segmentation of speech to generate a speech inventory, the method comprising:

  • initializing, via a processor, a Hidden Markov Model (HMM) using seed input data;

    performing a segmentation of the HMM into speech units to generate phone labels;

    correcting, via the processor, the segmentation of the speech units by performing the steps;

    re-estimating the HMM based on a current version of the phone labels;

    embedded re-estimating of the HMM; and

    updating the current version of the phone labels using spectral boundary correction.
