Title

LINGUISTICS COLLOQUIUM: "Speech Technology & Applications"

Description

Abstract: The talk will cover several branches of speech technology, including Automatic Speech Recognition, Phoneme Indexing and Audio Retrieval, Spoken Language Identification, Speaker Identification, Verification, Speech Synthesis, audio and prosodic feature extraction, and Natural Language Processing (NLP). It will discuss research and development that apply the components of speech technology and NLP for various operational applications ranging from multimedia cross-lingual information retrieval, voice command and control of electronic medical record systems for medical data entry and retrieval, intelligent situation awareness and communication for unmanned systems, voice biometrics for authentication on mobile devices and mining audio cues from PTSD interview recordings.

Title

LINGUISTICS COLLOQUIUM: "Race, class and gender in deracialising middle-class South African English: the sociophonetics of schwa today”

Description

Abstract:
New economic and educational opportunities have seen the rapid growth of a black middle-class in South Africa, part of whose making is having its children study at elite schools previously reserved for whites. These “model-C” schools are now important multiracial sites for varying degrees of deracialisation, or at least cross-cultural influences denied to previous generations. The present study tracks the degree to which class and gender are factors related to acquisition and allegiance to elite varieties of English or more traditional Black South African English. The illustrative variable in this paper is schwa, which may not seem a promising candidate vowel to illuminate the large-scale sociolinguistic and socio-political change discussed above. As Silverman (2011:628) observes of standard varieties, schwa is short in duration, [...] open to significant co-articulatory effects, and gravitates towards the centre of the vowel space. Furthermore, the acoustically based forced-alignment programme FAVE recommends discarding vowels in a data set that are less than 0.05 seconds in duration. However, for Black South African English schwa often takes on the quality of “full” vowels, and has “super-long” tokens in penultimate heavy syllables: seriously (0.304 sec), audiology (0.203 sec), academically (0.123 sec).

The data is broken up into seven subsets: initial, final, and medial positions (where there are 5 subtypes in traditional L2 Black South African English, realised as [a e i o u]). Acoustic analysis involved an adaptation of FAVE to South African norms. Statistical analysis of 4746 tokens was undertaken in R for each subset, using lmer and c-trees. The results give robust evidence of ongoing bifurcation by class (mediated by type of school) and gender. For the latter differences occur in more salient positions, most notably for F1 (vowel height) of final (or unchecked) schwa. Labov’s (2001:291) proposal that “in stable situations, women perceive and react to prestige or stigma more strongly than men do, and when change begins, women are quicker and more forceful in employing the new social symbolism, whatever it might be” is relevant here. This African case study shows that Labov’s proposition can be extended to the acquisition of a new elite crossover variety that accompanied and entrenched middle-class formation within a short period of a post-apartheid order.
