title: Temporally pre-presented lipreading cues release speech from informational masking.
abstract: Listeners can use temporally pre-presented content cues and concurrently presented lipreading cues to improve speech recognition under masking conditions. This study investigated whether temporally pre-presented lipreading cues also unmask speech. In a test trial, before the target sentence was co-presented with the masker, either target-matched (priming) lipreading video or static face (priming-control) video was presented in quiet. Participants' target-recognition performance was improved by a shift from the priming-control condition to the priming condition when the masker was speech but not noise. This release from informational masking suggests a combined effect of working memory and cross-modal integration on selective attention to target speech.
