ACOUSTIC CHARACTERISTICS OF TENSE AND LAX VOWELS ACROSS SENTENCE POSITION IN CLEAR SPEECH by Lindsay Roesler A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Communication Sciences and Disorders at The University of Wisconsin-Milwaukee August 2013 ABSTRACT ACOUSTIC CHARACTERISTICS OF TENSE AND LAX VOWELS ACROSS SENTENCE POSITION IN CLEAR SPEECH by Lindsay Roesler The University of Wisconsin-Milwaukee, 2013 Under the Supervision of Professor Jae Yung Song The purpose of this study was to examine the acoustic characteristics of tense and lax vowels across sentence positions in clear speech. Recordings were made of 12 participants reading monosyllabic target words at varying positions within semantically meaningful sentences. Acoustic analysis was completed to determine the effects of Style (clear vs. conversational), Tenseness (tense vs. lax), and Position (sentence-medial vs. sentence-final) on vowel duration, vowel space area, vowel space dispersion, and vowel peripheralization.
