Purpose: The mental lexicon of words used for spoken word recognition has been modeled as a complex network or graph. Do the characteristics of that graph reflect processes involved in its growth (M. S. Vitevitch, 2008) or simply the phonetic overlap between similar-sounding words? Method: Three pseudolexicons were generated by randomly selecting…

In three experiments, 3-, 4-, and 5-year olds and adults identified words from a list presented by a single talker or multiple talkers. Subjects were less accurate identifying or slower repeating words spoken by multiple speakers than by a single speaker. Processing of multiple speakers' words became easier with age. Children matched their…

Discusses experiments that investigated the sources of knowledge that are employed in spoken word identification. The interactive assumption that normal spoken word identification processes require the presence of semantic and syntactic context and the special status given to word-initial acoustic-phonetic information in cohort theory were…

This 21st annual progress report summarizes research activities on speech perception and spoken language processing carried out in the Speech Research Laboratory, Department of Psychology, Indiana University in Bloomington. As with previous reports, the goal is to summarize accomplishments during 1996 and 1997 and make them readily available. Some…

Notes that speech intelligibility has traditionally been measured by presenting words mixed in noise to listeners for identification at different signal-to-noise ratios. The words are produced in isolation or in sequence contexts where the predictability of specific items can be varied. Emphasizes that the technique provides valuable data about…
