Abstract : This dissertation is an experimental investigation of vowel duration. It focuses on phonetic and phonological aspects of vowel duration in Civili, an African language spoken in Gabon and some of its neighboring countries. It attempts to bring new insights into the phenomenon of vowel lengthening, and to assess the implications of these insights for standardizing the orthography of this language. The dissertation contains six chapters. In Chapter 1, the specific aims of and rationale for the study are given and the research problem is demarcated. Furthermore, the potential impact of the study, the methodological approach adopted, and the sociolinguistic situation of Civili are presented. Chapter 2 introduces the issues surrounding Civili vowel duration as the research problem of the study. The problem is presented as being both descriptive and orthographic in nature. In Chapter 2, the data and analyses of previous studies related to the phenomenon are assessed. This chapter also shows the importance of using both acoustic and perception data when studying vowel duration in Civili. Chapter 3 focuses on the physical nature of Civili vowel duration. It reports on the acoustic analyses and vowel duration measurements performed on selected words from the corpus. The chapter aims to show that natural duration is one of the acoustic features related to vowels which should be taken into consideration in various phonological analyses. Chapter 4 focuses on the auditory nature of Civili vowel duration. It introduces a perception experiment conducted with native speakers of Civili during this study. The aim of this experiment was to determine the perceived duration of vowels. This chapter contains the obtained experimental data and analyses thereof. Chapter 5 provides detail on the input of experimental data into the phonological description of vowel duration in Civili. This chapter also re-explores the phonological analyses from previous studies, as well as from the present study which integrates phonetic (experimental) data and phonological analyses. Chapter 6 draws the general conclusion of this study on the Civili vowel duration by listing the acoustic, the perceptual, and the phonological findings. This chapter also makes recommendations for the standardization of the Civili orthography as far as its vowel system is concerned. Then, the chapter presents implications for phonological theory and human language technologies. Finally, it provides suggestions for further research, including research on other Gabonese languages.
