Belief Shift or Only Facilitation: How Semantic Expectancy Affects Processing of Speech Degraded by Background Noise

Belief Shift or Only Facilitation: How Semantic Expectancy Affects Processing of Speech Degraded by Background Noise

Individuals use semantic expectancy - applying conceptual and linguistic knowledge to speech input - to improve the accuracy and speed of language comprehension. This study tested how adults use semantic expectancy in quiet and in the presence of speech-shaped broadband noise at -7 and -12 dB signal-to-noise ratio. Twenty-four adults (22.1 ± 3.6 years, mean ±SD) were tested on a four-alternativ...

Inference of Missing or Degraded Data for Noise Robust Speech Processing

OF THE DISSERTATION Inference of Missing or Degraded Data for Noise Robust Speech Processing by Bengt Jonas Borgström Doctor of Philosophy in Electrical Engineering University of California, Los Angeles, 2010 Professor Abeer Alwan, Chair In real world speech processing systems, speech signals are often corrupted by background acoustic noise or reverberation. Additionally, for systems which invo...

Semantic facilitation in bilingual everyday speech comprehension

Previous research suggests that bilinguals presented with low and high predictability sentences benefit from semantics in clear but not in conversational speech [1]. In everyday speech, how­ ever, many words are not highly predictable. Previous research has shown that native listeners can use also more subtle seman­ tic contextual information [2]. The present study reports two au­ ditory lexica...
