  • SELF-ORGANIZING UNIT RECOGNITION FOR SPEECH AND OTHER DATA SERIES
    Publication number: 20140142925
    Abstract: An approach automated processing for audio or other data series or signals, which is applicable where little or no transcribed training data is available, makes uses identification of self-organizing units (SOUs) in conjunction with automated creation of, or augmentation of an existing dictionary, with “pseudo-words” or tokens represented in terms of the SOUs. In some examples, the dictionary is iteratively updated (e.g., augmented) during training, optionally with updating of models of the SOUs during the iteration.
