Abstract
A fundamental issue in speech perception is the fact that information is spread over time. This raises the question of how listeners integrate acoustic information in real-time. One possibility is that cues are utilized as soon as they arrive to partially activate lexical candidates. Alternatively, input could be a buffered, until sufficient information is available to make a decision. Between these extremes, listeners may vary depending on the usefulness of a given cue, and whether it directly cues a phonetic contrast, or serves as context (e.g., talker identity) for interpreting other cues. We examined this in word-final and initial fricative contrasts using the visual world paradigm. Participants selected a visual referent of an auditory word (ship), and we used the likelihood of fixating lexical competitors (sip/ship) at each point in time to determine when various factors affected higher level decision making. Several studies contrasted the order and utility of the cues (strong vs. weak in different positions), and direct cues vs. information like talker used for compensation. In general, listeners appear to use acoustic information immediately as it becomes available in real-time to lexical candidates.
