The present study aims to investigate the production of the voiced labiodental fricative /v/ of Saudi Arabian speakers of English in view of linguistic and extra-linguistic factors. The linguistic aspect focuses on the role of the position of the sound in words, initial and final, and the distribution of errors per word in view of more and less familiar words. The extra-linguistic factors include participants' lengths of stay in the US and their ages and the potential influence these may have on the accuracy of pronouncing the target sound /v/. The total number of the subjects is 20 (10 male and 10 female), and their ages range between 20 and 35, with Mean age 27. Data is elicited through participants' reading of a word list with the target sound in initial and final position. The data coding is performed through spectrographic analysis and rater judgments. The analysis employs descriptive statistics, a dependent t-test used to compare production errors between initial and final position, and correlation analyses through which subjects' length of stay in the US and age are correlated with their total number of errors in both word positions. The findings show that word-final position is more difficult in pronouncing the phoneme /v/ than word-initial position. In addition, when the voiced labiodental fricative /v/ is mispronounced, it is substituted with the voiceless labiodental fricative /f/. Also, the correlation analysis shows that the longer the subjects have stayed in the USA, the more accurate their pronunciation of the target sound is (and vice versa). A significant correlation is also found between age and accuracy of pronunciation, as the younger subjects have more accurate pronunciation. The results of this study provide empirical evidence in support of several language acquisition theories, such as Contrastive Analysis Hypothesis (Lado, 1957), Markedness Differential Hypothesis (Eckman, 1977) and Language Transfer Theory (Gass & Selinker, 1994), all of which claim the influence of learners' first language on their second language. In the context of this study, the substitution of the voiced labiodental fricative /v/ with its voiceless counterpart /f/ can be attributed to the fact that /f/ is the only labiodental fricative phoneme in the Arabic language.

abstract: This study analyzes the Spanish of native speakers from Northern Mexico in order to ascertain the presence of the voiced labiodental fricative segment [v] when the sound is orthographically represented with the letter `v'. The study examines some of the internal and external factors that predict the labiodental fricative pronunciation of the letter `v'. This study is based on the theoretical framework of phonology as described by Piñeros (2009) and Hualde (2005). The study examined all instances in the data when a sound is written with the letter `v' to investigate if the sound is pronounced as the faithful voiced plosive bilabial allophone [b] of the phoneme /b/, the spirantized allophone [β], or the voiced labiodental fricative allophone [v]. Four speakers, a male and a female with an incomplete secondary education, and a male and a female with a graduate level education participated in the study. All participants were interviewed for one hour, read a word list, and read a paragraph provided by the researcher. The researcher coded the data using the phonetic analysis software Praat and all data were statistically analyzed using the multivariate software analysis program Goldvarb X in order to investigate the presence of the voiced labiodental fricative allophone [v] and predict what internal and external factors most influence its production. From this study it is obvious that the most influential factor favoring the realization of the labiodental fricative allophone [v] is orthography. When the phonetic segment was represented with the grapheme , the phonetic realization was more likely to be the labiodental fricative [v]. The level of education of the speaker and the formality of the stylistic setting were also determined to be influential factors. Speakers with a higher degree of education and stylistic settings with a higher degree of formality favored the realization of the labiodental fricative [v]. With regards to the internal factors, rather than external factors, a preceding phonological segment of a vowel or fricative dental [s] also favored the realization of the labiodental fricative [v]. / Dissertation/Thesis / M.A. Spanish 2012
