Abstract
Current models of speech perception suggest that combining acoustic cues and factoring out contextual variability allows listeners to recognize speech across different talkers. However, it remains unclear which specific cues are necessary and how their use varies between individual talkers. We use graph theoretic techniques to address these problems by constructing networks connecting talkers and possible cues. We identify subgraphs (Steiner trees) that connect talkers via cues consistently used to indicate specific phonemes. Classifiers trained on these cues match listeners\' data better than those trained on all cues, suggesting that Steiner trees can identify the cues necessary for speech recognition.
