Foreigner-directed speech and L2 speech learning in an understudied interactional setting: the case of foreign-domestic helpers in Oman

Ph. D. (Integrated) ThesisSet in Arabic-speaking Oman, the present study investigates whether speech directed to foreign domestic helpers (FDH-directed speech) is modified when compared with speech addressed to native Arabic speakers. It also explores the FDH’s ability to learn the sound system of their L2 in a near-naturalistic setting. In relation to input, the study explores whether there are any adaptations in native speakers’ realizations of complex Arabic consonants, consonant clusters, and vowels in FDH-directed speech. By doing so, it compares the phonetic features of FDH-directed speech in relation to other speech registers such as foreigner-directed speech (FDS), infant-directed speech (IDS) and clear speech. The study also investigates whether foreign accentedness, religion and Arabic language experience, as indexed by length of residence (LoR), play a role in the extent of adaptations present in FDH-directed speech. In relation to L2 speech learning, the study investigates the extent to which FDHs are sensitive to the phonemic contrasts of Arabic and whether their production of complex Arabic consonants and consonant clusters is target-like. It also examines the social and linguistic factors (LoR, first and second language literacy) that play a role in the learnability of these sounds. Speech recordings were collected from 22 Omani female native Arabic speakers who interacted 1) with their FDHs and 2) with a native-speaking adult (the order was reversed for half of the participants), in both instances using a spot the difference task. A picture naming task was then used to collect data for production data by the same FDHs, while perception data consisted of an AX forced choice task. Results demonstrate the distinctiveness of FDH-directed speech from other speech registers. Neither simplification of complex sounds nor hyperarticulation of consonant contrasts were attested in FDH-directed speech, despite them being reported in other studies on FDS and IDS. We attribute this to the familiarity of the native speakers with their FDHs and the formulaic nature of their daily interactions. Expansion of vowel space was evident in this study, conforming with other FDS studies. Results from perception and production tasks revealed that FDHs fell short of native-like performance, despite the more naturalistic setting and regardless of LoR. L1 and L2 literacy played varying roles in FDHs’ phonological sensitivity and production of certain contrasts. The study is original is terms of showing that FDS is not an automatic outcome of interactions with L2 speakers and links these results with the unusual social setting

Psycho-Social Constraints on Naturalistic Adult Second Language Acquisition

The following study investigated a rare case of adult immersion in a second language context without prior exposure to the language. It aimed to investigate whether Length of Residence (LoR) acts as a strong index of L2 speech performance when coupled with daily exposure and interaction with first language speakers. Twenty-two females from Africa and Asia who worked as Foreign Domestic Helpers (FDH) in Omani homes and with varying LoRs performed an AX discrimination and a production task which tapped into Omani consonants and clusters that are absent from their L1s; their accent was also rated by L1 Omani listeners. Results showed a surprising lack of significance of LoR on all the production and perception measures examined. Discrimination results showed a low sensitivity to Arabic consonantal contrasts that are lacking in the L1 across all participants, and a small positive effect of L1 literacy. Production results exhibited low accuracy on all Arabic consonants and a marked foreign accent as judged by L1 listeners, with a small positive effect of L2 literacy. We argue that the nature of the interactions between FDH and employers, along with uneven power relations and social distance, counteract any advantage of LoR and the immersion setting examined here
