Acoustic Characteristics Of Word-Final American English Liquids Produced By L2 Adult Speakers, Judith A. Espinal
Acoustic Characteristics Of Word-Final American English Liquids Produced By L2 Adult Speakers, Judith A. Espinal
LSU Master's Theses
In this study, the acoustic differences between native English speakers’ (L1) and native-Korean speakers’ (L2) production of American English liquids /ɹ/, /l/ and /ɹl/ were examined among 14 Korean speakers and 13 English speakers. Temporal measures included (1) relative timing of maximum constriction and (2) duration of vocalic nuclei. Spectral measures included (1) Euclidean distance between /ɹ/ and /l/ and (2) frequency difference between F2 and F3. The results indicated a significant interaction between speaker group and phonetic stimuli. That is, L2 speakers produced a similar degree of constriction across semivowels, whereas L1 speakers produced varying degrees of F2-F3 constrictions …
Acoustic Characteristics Of Vowels Produced By Young Children From The New Orleans Area, Rebecca E. Dorsa
Acoustic Characteristics Of Vowels Produced By Young Children From The New Orleans Area, Rebecca E. Dorsa
LSU Master's Theses
Understanding dialects and their effects on speech and language is integral to the field of speech-language pathology, as dialectal differences could potentially be misdiagnosed as speech or language disorders if these factors are not well-considered. The number and organization of the vowel system of one regional dialect of American English differs from those of another regional dialects. Therefore, understanding the effect of dialect on vowel productions in children can aid in the accurate evaluation of children from various dialectal backgrounds. The aims of the proposed study were to 1) determine the age at which young children develop acoustic markers of …
