Stage Monologue and its Linguistic Features (Textual and Prosodic Analysis)

Spoken language production is considered to be one of the most difficult aspects of teaching a foreign language. It usually involves mastering pronunciation of sounds and intonation. If nowadays many teachers do not worry about the phonetic details of sounds, there is still focus on intonation as it has a great impact on the comprehensibility of the learner’s English. This is a very important issue for future teachers because correctness of pronunciation is one of the goals of any spoken language programme, with students asked to produce quite extended spoken monologues and to follow the requirements of various intonational styles. The aim of this study is to analyse textual and prosodic characteristics of stage monologue – a text produced on a theatre stage or in a film. Analytical methods were applied in order to obtain information about textual features and prosodic stylistic markers such as pitch level, range, tone modifications, loudness, and tempo, and also to develop style-forming factors in stage monologue. Results show that the stage monologues analysed possess all necessary characteristics of a text: informational content, delimitation, continuum, coherence, cohesion and completeness. Further analysis of stage monologue showed that it can be characterised by such specific features as expressiveness, normativeness, effectiveness, and conversational character. Stage monologues also possess all necessary prosodic markers. Certain style-forming factors of stage monologue were also developed in this study, including delimitation, accentuation of key words, thematic centres and expressively prominent centres, type of composition scheme, and theme. These results will be of significant pedagogical value to students who intend to become English teachers, and to teachers involved in linguistics research.

Listener Detection of Objectively Validated Acoustic Features of Speech in Huntington’s Disease

Background: Subtle progressive changes in speech motor function and cognition begin prior to diagnosis of Huntington’s disease (HD). Objective: To determine the nature of listener-rated speech differences in premanifest and early-stage HD (i.e., PreHD and EarlyHD), compared to neurologically healthy controls. Methods: We administered a speech battery to 60 adults (16 people with PreHD, 14 with EarlyHD, and 30 neurologically healthy controls), and conducted a cognitive test of processing speed/visual attention, the Symbol Digit Modalities Test (SDMT) on participants with HD. Voice recordings were rated by expert listeners and analyzed for acoustic and perceptual speech features. Results: Listeners perceived subtle differences in the speech of PreHD compared to controls, including abnormal pitch level and speech rate, reduced loudness and loudness inflection, altered voice quality, hypernasality, imprecise articulation, and reduced naturalness of speech. Listeners detected abnormal speech rate in PreHD compared to healthy speakers on a reading task, which correlated with slower speech rate from acoustic analysis and a lower cognitive performance score. In early-stage HD, continuous speech was characterized by longer pauses, a higher proportion of silence, and slower rate. Conclusion: Differences in speech and voice acoustic features are detectable in PreHD by expert listeners and align with some acoustically-derived objective speech measures. Slower speech rate in PreHD suggests altered oral motor control and/or subtle cognitive deficits that begin prior to diagnosis. Speakers with EarlyHD exhibited more silences compared to the PreHD and control groups, raising the likelihood of a link between speech and cognition that is not yet well characterized in HD.

Pitch It Right: Using Prosodic Entrainment to Improve Robot-Assisted Foreign Language Learning in School-Aged Children

Robot-assisted language learning (RALL) is a promising application when employing social robots to help both children and adults acquire a language and is an increasingly widely studied area of child–robot interaction. By introducing prosodic entrainment, i.e., converging the robot’s pitch with that of the learner, the present study aimed to provide new insights into RALL as a facilitative method for interactive tutoring. It is hypothesized that pitch-level entrainment by a Nao robot during a word learning task in a foreign language will result in increased learning in school-aged children. The results indicate that entrainment has no significant effect on participants’ learning, contra the hypothesis. Research on the implementation of entrainment in the context of RALL is new. This study highlights constraints in currently available technologies for voice generation and methodological limitations that should be taken into account in future research.

The effects of therapeutic group singing on voice, cough and quality of life in parkinson’s disease

Purpose: To examine the effect of a group therapeutic singing intervention on voice, cough, and quality of life in persons with Parkinson Disease (PD) in a community-based outpatient setting using a repeated measures design.Methods: 19 volunteer participants with PD completed the study. Ten participants participated in the intervention and nine served voluntarily as controls. Participants completed one hour group singing sessions over 12 weeks led by a music therapist. Sessions consisted of 30 min of high intensity vocal exercise and 15 to 20 minutes of group singing. Data on phonation, speech, cough, and quality of life were collected pre-intervention and one week post intervention with final data collection 12 weeks post-intervention.Results: No significant change in voice measures although 50% of participants showed improvement. A main effect was found for breathiness (p=0.023), appropriate pitch level (p=0.037) and speaking rate (p=0.009). No main effect for cough but pairwise comparisons were nearly significant pre to post intervention (p=0.053) and pre-intervention to final follow up (p=0.023). No main effect found for QOL but singing participants demonstrated better QOL scores than controls.Conclusions: Results from this small sample suggest that there are some speech benefits from singing intervention as well as potential improvement in cough for airway clearance. Additional study is needed to confirm these results.

Design and Validation of an Observational System for Penalty Kick Analysis in Football (OSPAF)

The analysis of penalty kick has played an important role in performance analysis. The study aims are to get formal feedback on the relevance of variables for penalty kick analysis, to design and validate an observational system; and to assess experts’ opinion on the optimum video footage in penalty kick analysis. A structured development process was adopted for content validity, reliability and agreement on video usage. All observational variables included in OSPAF showed Aiken’s V values above the cut-off (for 5-scale V> 0.64; for 2-scale = V > 0.75; p < 0.05). Cohen’s Kappa resulted in mean intra- and inter-rater reliability values of 0.90 and 0.86, respectively. It is recommended to combine at least three different viewing angles (V = 0.90; p = 0.006) with standardization of video quality (V = 0.95; p = 0.006). Changing the viewing angles may influence the observer perception (V = 0.86; p = 0.006). The aerial and pitch-level viewing angle behind the penalty taker and pitch-level viewing angle behind the goalkeeper were indicated as most appropriate for observational analysis (V = 0.97; p = 0.01). The OSPAF met all requirements of instrument validation. It may be recommended as basis of future observational systems on penalty kicks.

Exploring the Complexity of the L2 Intonation System: An Acoustic and Eye-Tracking Study

Phonological research has demonstrated that English intonation, variably referred to as prosody, is a multidimensional and multilayered system situated at the interface of information structure, morphosyntactic structure, phonological phenomena, and pragmatic functions. The structural and functional complexity of the intonational system, however, is largely under-addressed in L2 pronunciation teaching, leading to a lack of spontaneous use of intonation despite successful imitation in classrooms. Focusing on contrastive and implicational sentence stress, this study explored the complexity of the English intonation system by investigating how L1 English and Mandarin-English L2 speakers use multiple acoustic features (i.e., pitch range, pitch level, duration, and intensity) in signaling contrastive and implicational information and how one acoustic feature (maximum pitch level) is affected by information structure (contrast), morphosyntactic structure (phrasal boundary), and a phonological phenomenon (declination) in L1 English and Mandarin-English L2 speakers' speech. Using eye-tracking technology, we also investigated (1) L1 English and Mandarin-English L2 speakers' real-time processing of lexical items that carry information structure (i.e., contrast) and typically receive stress in L1 speakers' speech; (2) the influence of visual enhancement (italics and bold) on L1 English and Mandarin-English L2 speakers' processing of contrastive information; and (3) L1 English and Mandarin-English L2 speakers' processing of pictures with contrastive information. Statistical analysis using linear mixed-effects models showed that L1 English speakers and Mandarin-English L2 speakers differed in their use of acoustic cues in signaling contrastive and implicational information. They also differed in the use of maximum pitch level in signaling sentence stress influenced by contrast, phrasal boundary, and declination. We did not find differences in L1 English and Mandarin-English L2 speakers' processing of contrastive and implicational information at the sentence level, but the two groups of participants differ in their processing of contrastive information in passages and pictures. These results suggest that processing limitations may be the reason why L2 speakers did not use English intonation spontaneously. The findings of this study also suggest that Complexity Theory (CT), which emphasizes the complex and dynamic nature of intonation, is a theoretical framework that has the potential of bridging the gap between L2 phonology and L2 pronunciation teaching.

The Trini Sing-Song: Sociophonetic variation in Trinidadian English prosody and differences to other varieties

The current study provides a phonetic perspective on the questions of whether a high degree of variability in pitch may be considered a characteristic, endonormative feature of Trinidadian English (TrinE) at the level of speech production and contribute to what is popularly described as ‘sing-song’ prosody. Based on read and spontaneous data from 111 speakers, we analyze pitch level, range, and dynamism in TrinE in comparison to Southern Standard British (BrE) and Educated Indian English (IndE) and investigate sociophonetic variation in TrinE prosody with a view to these global F0 parameters. Our findings suggest that a large pitch range could potentially be considered an endonormative feature of TrinE that distinguishes it from other varieties (BrE and IndE), at least in spontaneous speech. More importantly, however, it is shown that a high degree of pitch variation in terms of range and dynamism is not as much characteristic of TrinE as a whole as it is of female Trinidadian speakers. An important finding of this study is that pitch variation patterns are not homogenous in TrinE, but systematically sociolinguistically conditioned across gender, age, and ethnic groups, and rural and urban speakers. The findings thus reveal that there is a considerable degree of systematic local differentiation in TrinE prosody. On a more general level, the findings may be taken to indicate that endonormative tendencies and sociolinguistic differentiation in TrinE prosody are interlinked.

constituents introduced by theming markers in French in the face of anteposed spatio-temporal complements

This paper discusses the prosodic properties of sentence-initial spatio-temporal adverbials and of PPs introduced by so-called 'thematic markers' (TMCs), such as en ce qui concerne ('as for') or du point de vue de ('with regard to'). Their function is to indicate the aboutness-topic (a.o. Reinhart 1981, Gundel 1989, Lambrecht 1994) (1) or the topic Chinese style (Chafe 1976) (2). (1) Concernant le programme, il doit différer selon les universités et les profs. (2) Mais quand on peut il faut impérativement regarder BBC News. En ce moment, au niveau de l'info, ils sont vraiment au top. (YCCQA, De Smet 2009) Mertens (2008) hypothesizes that in certain syntactic constructions such as left dislocations, (pseudo-)clefts and certain adjuncts, the articulation between the left detached element (the dislocated element, the focus of the cleft, the adjunct) and the main clause is followed by a major prosodic boundary, i.e. they end on a relative high pitch level. It appears from our corpus that most TMCs end on such a major prosodic boundary (73%). As for sentence-initial spatio-temporal PPs, only 41% end on a major prosodic boundary. There are two important differences between TMCs and sentence-initial spatio-temporal PPs which explain that a strong prosodic boundary at the end of a TMC is more frequent than at the end of sentence-initial spatio-temporal adverbials. Semantically, sentence-initial spatio-temporal adverbials always limit the application range of the main clause, but not all TMCs affect the truth values of the proposition. Some can be omitted without changing the signification of the clause. On the syntactic level, sentence-initial spatio-temporal adverbials can always appear in the scope of a cleft or can be moved towards the end of the utterance without the proposition becomes ungrammatical. TMCs which affect the truth values of the proposition can also appear in the scope of the cleft or can be moved to the end of the proposition. TMCs which do not affect the truth values of the proposition do not allow these syntactic tests. Possibility of clefting, movement and specification of the main clause are used as tests (a.o. Melis 1983, Blanche-Benveniste et al. 1990) to show whether a constituent is linked to the verb phrase. This paper shows that sentence-initial spatial-temporal PPs are linked to the verb phrase, but that this is not the case for all TMCs. These syntactic and semantic observations explain the high frequency of the strong prosodic boundary at the end of a TMC.

Polytonia

This paper first proposes a labeling scheme for tonal aspects of speech and then describes an automatic annotation system using this transcription. This fine-grained transcription provides labels indicating pitch level and pitch movement of individual syllables. Of the five pitch levels, three (low, mid, high) are defined on the basis of pitch changes in the local context and two (bottom, top) are defined relative to the boundaries of the speaker’s global pitch range. For pitch movements, both simple and compound, the transcription indicates direction (rise, fall, level) and size, using size categories (pitch intervals) adjusted relative to the speaker’s pitch range. The automatic tonal annotation system combines several processing steps: segmentation into syllable peaks, pause detection, pitch stylization, pitch range estimation, classification of the intra-syllabic pitch contour, and pitch level assignment. It uses a dedicated and rule-based procedure, which unlike commonly used supervised learning techniques does not require a labeled corpus for training the model. The paper also includes a preliminary evaluation of the annotation system, for a reference corpus of nearly 14 minutes of spontaneous speech in French and Dutch, in order to quantify the annotation errors. The results, expressed in terms of standard measures of precision, recall, accuracy and Fmeasure are encouraging. For pitch levels low, mid and high an F-measure between 0.946 and 0.815 is obtained and for pitch movements a value between 0.708 and 1. Provided additional modules for the detection of prominence and prosodic boundaries, the resulting annotation may serve as an input for a phonological annotation.

From image to text to speech: the effects of speech prosody on information sequencing in audio description

Given the extensive body of research in audio description – the verbal-vocal description of visual or audiovisual content for visually impaired audiences – it is striking how little attention has been paid thus far to the spoken dimension of audio description and its para-linguistic, prosodic aspects. This article complements the previous research into how audio description speech is received by the partially sighted audiences by analyzing how it is performed vocally. We study the audio description of pictorial art, and one aspect of prosody is examined in detail: pitch, and the segmentation of information in relation to it. We analyze this relation in a corpus of audio described pictorial art in Finnish by combining phonetic measurements of the pitch with discourse analysis of the information segmentation. Previous studies have already shown that a sentence-initial high pitch acts as a discourse-structuring device in interpreting. Our study shows that the same applies to audio description. In addition, our study suggests that there is a relationship between the scale in the rise of pitch and the scale of the topical transition. That is, when the topical transition is clear, the rise of pitch level between the beginnings of two consecutive spoken sentences is large. Analogically, when the topical transition is small, the change of the sentence-initial pitch level is also rather small.
