Primary Means

Interviews have been used for decades in empirical inquiry across the social sciences as one or the primary means of generating data. In applied linguistics, interview research has increased dramatically in recent years, particularly in qualitative studies that aim to investigate participants’ identities, experiences, beliefs, and orientations toward a range of phenomena. However, despite the proliferation of interview research in qualitative applied linguistics, it has become equally apparent that there is a profound inconsistency in how the interview has been and continues to be theorized in the field. This article critically reviews a selection of applied linguistics research from the past 5 years that uses interviews in case study, ethnographic, narrative, (auto)biographical, and related qualitative frameworks, focusing in particular on the ideologies of language, communication, and the interview, or the communicable cartographies of interviewing, that are evident in them. By contrasting what is referred to as an interview as research instrument perspective with a research interview as social practice orientation, the article argues for greater reflexivity about the interview methods that qualitative applied linguists use in their studies, the status ascribed to interview data, and how those data are analyzed and represented.

Speech And Audio Coding

A bandwidth extension (BWE) algorithm from wideband to superwideband (SWB) is proposed for a scalable speech/audio codec that uses modified discrete cosine transform (MDCT) coefficients as spectral parameters. The superwideband is first split into several subbands that are represented as gain parameters and normalized MDCT coefficients in the proposed BWE algorithm. We then estimate normalized MDCT coefficients of the wideband to be fetched for the superwideband and quantize the fetch indices. After that, we quantize gain parameters by using relative ratios between adjacent subbands. The proposed BWE algorithm is embedded into a standard superwideband codec, the SWB extension of G.729.1 Annex E, and its bitrate and quality are compared with those of the BWE algorithm already employed in the standard superwideband codec. It is shown from the comparison that the proposed BWE algorithm relatively reduces the bitrate by around 19% with better quality, compared to the BWE algorithm in the SWB extension of G.729.1 Annex E.
