This study examined changes in the sentence intelligibility scores of speakers with dysarthria in association with different signal-independent factors (contextual influences). This investigation focused on the presence or absence of iconic gestures while speaking sentences with low or high semantic predictiveness. The speakers were 4 individuals with dysarthria, who varied from one another in terms of their level of speech intelligibility impairment, gestural abilities, and overall level of motor functioning. Ninety-six inexperienced listeners (24 assigned to each speaker) orthographically transcribed 16 test sentences presented in an audio + video or audio-only format. The sentences had either low or high semantic predictiveness and were spoken by each speaker with and without the corresponding gestures. The effects of signal-independent factors (presence or absence of iconic gestures, low or high semantic predictiveness, and audio + video or audio-only presentation formats) were analyzed for individual speakers. Not all signal-independent information benefited speakers similarly. Results indicated that use of gestures and high semantic predictiveness improved sentence intelligibility for 2 speakers. The other 2 speakers benefited from high predictive messages. The audio + video presentation mode enhanced listener understanding for all speakers, although there were interactions related to specific speaking situations. Overall, the contributions of relevant signal-independent information were greater for the speakers with more severely impaired intelligibility. The results are discussed in terms of understanding the contribution of signal-independent factors to the communicative process.

Phonetic Instruction

The paper addresses a very important aspect of Polish-accented English, namely the issue of frequent phonetic errors made by Polish learners which do not result from their inability to produce foreign sounds correctly, but which stem from various interference factors (e.g foreign pronounced as [fo’rejn]). Following Szpyra-Kozłowska’s (in press a) claims that such errors hinder successful communication far more than other segmental and suprasegmental inaccuracies and should thus be treated as a top pedagogical priority, what is suggested is a shift in phonetic instruction from the focus on the production of sounds and prosodies to the focus on the pronunciation of problematic words. Our major goal is to demonstrate how this proposal can be implemented in the language classroom. The authors present a report on the experiment in which a group of 25 Polish secondary school pupils has undergone a special training in the pronunciation of 50 commonly mispronounced words with the use of special, teacher-designed materials. The effectiveness of the employed procedure as well as the pupils’ reactions to it are examined and pedagogical conclusions are drawn.

A speech synthesizer was developed that operates by summing exponentially damped sinusoids at frequencies and amplitudes corresponding to peaks derived from the spectrum envelope of the speech signal. The spectrum analysis begins with the calculation of a smoothed Fourier spectrum. A masking threshold is then computed for each frame as the running average of spectral amplitudes over an 800-Hz window. In a rough simulation of lateral suppression, the running average is then subtracted from the smoothed spectrum (with negative spectral values set to zero), producing a masked spectrum. The signal is resynthesized by summing exponentially damped sinusoids at frequencies corresponding to peaks in the masked spectra. If a periodicity measure indicates that a given analysis frame is voiced, the damped sinusoids are pulsed at a rate corresponding to the measured fundamental period. For unvoiced speech, the damped sinusoids are pulsed on and off at random intervals. A perceptual evaluation of speech produced by the damped sinewave synthesizer showed excellent sentence intelligibility, excellent intelligibility for vowels in /hVd/ syllables, and fair intelligibility for consonants in CV nonsense syllables.

The Given

Abstract The management of given and new information is one of the key components of accomplishing coherence in oral discourse, which is claimed to be a problematic area for language learners (Celce-Murcia, Dörnyei, and Thurrell 1995: 14). Research on discourse intonation proposes that instead of the given/new dichotomy, givenness should be viewed as a continuum, with different types of accessibility (Baumann & Grice 2006). Moreover, Prince (1992) previously categorized information structure into Hearer-old/Hearer-new and Discourse-old/Discourse-new information. There is consensus on the fact that focus or prominence associated with new information is marked with nuclear pitch accent, and its main acoustic cue, fundamental frequency (f0) (Ward & Birner 2001: 120). Non-native intonation has been reported to display numerous differences in f0 range and patterns compared to native speech (Wennerstrom 1994; Baker 2010). This study is an attempt to address the issue of marking information structure in existential there sentences by means of f0 in non-native spontaneous speech. Data originates from task-based interactions in the Wildcat Corpus of Native- and Foreign-Accented English (Van Engen et al. 2010). This paper examines two issues: (1) information structure in relation to the notions of givenness and different types of accessibility (Baumann & Grice 2006) and to Prince’s (1992) multidimensional taxonomy and (2) the use of f0 peaks to mark the prominence of new information. Several differences were measured among native speakers regarding the use of f0, sentence type, and complexity.

Hong Kong English is to a certain extent a standardized English variety spoken in a bilingual (English-Cantonese) context. In this article we compare this (native) variety with English as a foreign language spoken by other Cantonese speakers, viz. learners of English in Guangzhou (mainland China). We examine whether the notion of standardization is relevant for intonation in this case and thus whether Hong Kong English is different from Cantonese English in a wider perspective, or whether it is justified to treat Hong Kong English and Cantonese English as the same variety (as far as intonation is concerned). We present a comparison between intonational contours of different sentence types in the two varieties, and show that they are very similar. This shows that, in this respect, a learned foreign-language variety can resemble a native variety to a great extent.

Unfamiliar second-language (L2) accents present a common challenge to speech understanding. However, the extent to which accurately-recognized unfamiliar L2-accented speech imposes a greater cognitive load than native speech remains unclear. The current study used pupillometry to assess cognitive load for native English listeners during the perception of intelligible Mandarin Chinese-accented English and American-accented English. Results showed greater pupil response (indicating greater cognitive load) for the unfamiliar L2-accented speech. These findings indicate that the mismatches between unfamiliar L2-accented speech and native listeners’ linguistic representations impose greater cognitive load even when recognition accuracy is at ceiling.

The Relationship

Purpose Dysarthria is a consequence of multiple sclerosis (MS) that can co-occur with cognitive impairment. Clinical management thus requires understanding the separate and combined effects of dysarthria and cognitive impairment on functional communication in MS. This study compared perceptual measures of intelligibility and speech severity that capture functional communication deficits for 4 operationally defined groups with MS. The relationship between communication participation and perceptual measures was also examined. Method Forty-eight adults with MS and 12 healthy controls participated. Cognitive testing and dysarthria diagnosis determined group assignment: (a) MS with cognitive impairment (MSCI), (b) MS with a diagnosis of dysarthria and no cognitive impairment (MSDYS), (c) MS with dysarthria and cognitive impairment (MSDYS + CI), and (d) MS without dysarthria or cognitive impairment (MS). Sentence Intelligibility Test scores, scaled speech severity obtained from the “Grandfather Passage,” and Communication Participation Item Bank (CPIB) scores were analyzed. Results Sentence Intelligibility Test scores approached 100% for all groups. Speech severity was greater for the MSDYS + CI and MSDYS groups versus controls. CPIB scores were greatest for the MSDYS + CI group and were not significantly correlated with either perceptual measure. Conclusions The CPIB and speech severity were sensitive to aspects of communication problems for some groups with MS not reflected in a measure of sentence intelligibility. Findings suggest the importance of employing a variety of measures to capture functional communication problems experienced by persons with MS.
