COMPARATIVE INTELLIGIBILITY FUNCTIONS AND SOME NORMATIVE DATA OF FOUR SPANISH WORD RECOGNITION ABILITY LISTS

Abstract

The investigator evaluated a commercially available Spanish word recognition ability test. The material consists of four lists of fifty bisyllabic tetraphonemic Spanish words available from Auditec of St. Louis as: "Spanish speech discrimination lists 1-4". Interlist equivalence, word difficulty, speaker's intelligibility, and P/I functions' slopes were investigated. Taped lists were presented to 16 normal hearing native Spanish speaking adults at four presentation levels. Statistical analysis indicated that the intelligibility of list three is significantly different than the other lists at the.05 level. At the low presentation levels, subjects of Mexican origin obtained better scores than subjects of other nationalities. The P/I functions' slope (4.3%) was comparable to that obtained by investigators of English tests. Most frequently missed words have as common denominators: presence of the /s/ sound, and are words that retain their meaning even after deletion of final /s/. Talker's speech intelligibility was judged to be very clear.
