The Crosslanguage Intelligibility of Phonemes, Sources of Interference in International Voice Communication. Final Technical Report.
Lindsay, Patricia Maurine; And Others
The intelligibility of crosslanguage voice communication in American English was studied in situations where the phonemes of that language are uttered by American speakers and identified by speakers of German, French, and Mexican Spanish and in situations where they are uttered by speakers of German, French, and Mexican Spanish and identified by Americans. Nonsense syllable consonants were used as test items. Test items were in English, since international air-traffic communications, the principal area of focus, are carried out mostly in English. The consonants occur in initial and terminal positions in monosyllabic items and intervocally in disyllabic items. Each consonant-times-position was repeated in front-, central-, and back-vowel contexts to determine if vowels differentially affect the perception of the consonants. All the phonetic conditions were repeated in each of three transmission conditions: restricted bandwidth, white noise background, and babbling voice background. Findings indicate that in terms of the classes of phonemes, the stops in final position were by far the most difficult phonemes to identify for all listeners. The stimuli most difficult to perceive were in the noise and babbling conditions in the terminal position. Consonants in intervocalic position were more readily identified than in the other two positions. Recommendations for the improvement of international voice communications are offered. (SW)
