Some evidence, mostly drawn from experiments using only a single moderate rate of speech, suggests that low-frequency amplitude modulations may be particularly important for intelligibility. Here, two experiments investigated intelligibility of temporally distorted sentences across a wide range of simulated speaking rates, and two metrics were used to predict results. Sentence intelligibility w...

Cochlear implant (CI) users' speech understanding may be influenced by different speaking styles. In this study, speech recognition was measured in Mandarin-speaking CI and normal-hearing (NH) subjects for sentences produced according to four styles: slow, normal, fast, and whispered. CI subjects were tested using their clinical processors; NH subjects were tested while listening to a four-chan...

SRI collected a corpus to study how spontaneous speech differs from other types of speech. The corpus was collected in two parts: (1) a spontaneous Switchboard-style conversation on an assigned topic, and (2) a reading session in which participants read transcripts of their conversation from part 1. Experiments were conducted on sentences with identical transcripts that varied in speaking style...

Literature is replete with the studies focusing on the role of vocabulary knowledge in second language receptive skills. However, the relationship between the aspects of vocabulary knowledge and productive skills in general, and the speaking performance in particular has remained scanty in the related literature. This paper examined the relationship between knowledge of L2 vocabulary size at di...

Although lexis research (e.g., Lewis, 1997; Taguchi, 2008) has already evidenced the possibility of teaching formulaic sequences (FS), further research is still needed to examine the procedures or frameworks through which the approach can be applied and probe the second or foreign language (L2) areas where it demonstrates more relevance. This pretest-posttest quasi-experimental study aimed, fir...
