Abstract In this article we assess the extent to which we can collect plausible data about regional dialect variation using crowdsourcing techniques – the BBC Future Survey – without explicitly gathering any user metadata, but relying instead on background information collected by Google Analytics. In order to do this, we compare this approach with another crowdsourced survey, operated from a smartphone application, which examines the same site – the British Isles – but which explicitly asks users to submit detailed social background information – the English Dialects App (EDA) (Leemann et al. 2018). The EDA has the disadvantage that there is a considerable user drop-off between completing the dialect survey and completing the social metadata questionnaire. The BBC Future Survey, however, only collects information on where users are physically located when they complete the survey – not where they are from or even where they live. Results show that the BBC Future Survey produces a plausible snapshot of regional dialect variability that can complement other more sophisticated (expensive, time-consuming) approaches to investigating language variation and change. We suggest the approach constitutes a digital-era rapid anonymous survey along the lines of Labov (1972), serving similar aims, with similar success, but on a much much larger scale.

English Dialect

School students (15–16 years) in six regions of Wales were recorded telling stories in their local English dialects. Some of these narratives were used as samples representing the main English dialect regions in Wales. Comparable groups of students (n = 169) and a group of teachers (n = 47) rated the audio-recorded speakers on a number of scales of affiliation, status, and Welshness. Statistical analysis of their ratings, employing cluster analysis and multidimensional scaling, made it possible to detect some of the competing or additive effects of dialect and narrative features. Judgments of “Welshness” of the speaker/narratives were grounded in the regional dialect properties; but other judgments, such as the likability of the speakers, tended to draw on features of both dialect and narrative. In addition, comparison of students and teachers revealed differences in their evaluations of particular dialect communities and the characteristics of the narratives. The findings illustrate the importance of approaching the analysis of dialect variation within the broader context of speech and discourse performance.

Phonetic Features

ABSTRACTSpeech intelligibility in a multitalker background can be affected by the language of both the talker and the interfering speech. This study investigated whether this interaction is modulated by dialect variations of the same language. American English listeners were presented with target sentences in either their own General American English (GAE) or a different accent (Southern American English [SAE]) masked by either GAE or SAE two-talker babble at three sound to noise ratios (SNRs): +3, 0, and –3 dB. All speech materials were produced by male talkers. Across all conditions, SAE target was more intelligible than GAE. Intelligibility of either target decreased as the level of the interfering babble noise increased. Target accent interacted with masking accent: at +3 dB SNR, GAE (and not SAE) was the more effective masker. The target-masker interaction was different as listening conditions deteriorated: at 0 and –3 dB SNR, masking accent did not affect GAE target, but when the target was SAE, the SAE masker (and not GAE) was more effective. Thus, at increased noise levels, listeners benefited from the mismatch between the target and masking accents only when the target was in a nonnative accent. These results demonstrate that dialect variation can influence listeners’ performance in a multitalker environment. The apparent asymmetry in intelligibility of accents may be in part related to dialect-specific prosodic and phonetic features.

Source Of Information

ABSTRACTA speaker's regional dialect is a rich source of information about that person. Two studies examined five- to six-year-old children's perception of regional dialect: Can they perceive differences among dialects? Have they made meaningful social connections to specific dialects? Experiment 1 asked children to categorize speakers into groups based on their accent; Experiment 2 asked them to match speakers to (un)familiar cultural items. Each child was tested with two of the following: the child's Home dialect, a Regional variant of that dialect, and a Second-Language variant. Results showed that children could successfully categorize only with a Home vs. Second-Language dialect contrast, but could reliably link cultural items with either a Home vs. Second-Language or a Regional vs. Second-Language dialect contrast. These results demonstrate five- to six-year-old children's developing perceptual skill with dialect, and suggest that they have a gradient representation of dialect variation.

Purpose The authors sought to investigate interactions among intelligibility-enhancing speech cues (i.e., semantic context, clearly produced speech, and visual information) across a range of masking conditions. Method Sentence recognition in noise was assessed for 29 normal-hearing listeners. Testing included semantically normal and anomalous sentences, conversational and clear speaking styles, auditory-only (AO) and audiovisual (AV) presentation modalities, and 4 different maskers (2-talker babble, 4-talker babble, 8-talker babble, and speech-shaped noise). Results Semantic context, clear speech, and visual input all improved intelligibility but also interacted with one another and with masking condition. Semantic context was beneficial across all maskers in AV conditions but only in speech-shaped noise in AO conditions. Clear speech provided the most benefit for AV speech with semantically anomalous targets. Finally, listeners were better able to take advantage of visual information for meaningful versus anomalous sentences and for clear versus conversational speech. Conclusion Because intelligibility-enhancing cues influence each other and depend on masking condition, multiple maskers and enhancement cues should be used to accurately assess individuals' speech-in-noise perception.
