Selection for Acoustic Coverage from Unlimited Speech Extracted from Closed-Captioned TV

Given unlimited amounts of speech training data, it is desirable to predict informative subsets that will still improve the resulting acoustic model. We present a triphone frequency threshold measure for predicting informative subsets from vast amounts of speech. Results with single pass decoding show that acoustic models built from our selection-based speech set perform better than when trained on similar amounts of non-selected speech, and perform similar to models built from the original, larger amount of speech.
