If speakers articulate clearly enough to meet the perceptual needs of their listeners, clarity should depend on what listeners know about (listener-Given) rather than on what speakers know about (speaker-Given). For words excerpted from spontaneous speech, however, intelligibility to naive adult listeners showed only effects of the speaker’s knowledge.(More)
This paper describes a resource for the study of spontaneous speech under stress, a corpus of 216 unscripted taskoriented dialogues conducted by normal Canadian adults in the course of a sleep deprivation experiment under 3 drug conditions. Speakers carried out the route-communication task (see [1]) in alternation with a battery of other tasks over a 6-day(More)

Running speech contains abundant assimilated and phonologically reduced tokens, but there is considerable debate about how such varied pronunciations disrupt access to the corresponding words in listeners’ mental lexicons. While previous studies have examined the effects of carefully produced or electronically edited reductions, we present two experiments(More)
