“Captain Grey and the Greedy Aliens”: Obtaining normative data on a new test for the production of verbs at sentence level in children
(2014)
Bridgeman, Ellen
Abstract:
Background: Children with specific language impairment (CwSLI) exhibit significant difficulties in language ability affecting areas such verb knowledge and verb production, producing fewer verbs and verb argument structures than typically developing (TD) children. As verbs are critical to sentence production it is also not surprising that they also produce fewer complex sentences. Although these areas of impairment are widely acknowledged there is a dearth of clinically available instruments that comprehensively assess verbs production and complex sentences in this population. Aims: To gather normative data from typically developing children aged 4;06-12;00 on their sentence complexity and production of verbs and their related argument structures using the newly developed story retell tool ‘Captain Grey and the Greedy Aliens’; to investigate the sensitivity of the assessment across the age ranges; to investigate the inter-rater reliability and clinical utility of the assessment; and...

A corpus-based lexico-grammatical analysis of the Limerick corpus of Irish English (L-CIE) : some nominal and verbal features
(2005)
Forde, Kieran
Abstract:
This study proposes to use a corpus-based approach to identify and evaluate some of the discrete features of spoken Southern Irish English. The features to be analysed were chosen on the basis that they were identified in the secondary literature, predominantly Harris (1993) and Filppula (1999) and are considered by those working in the field to be representative of the forms that make SIE a distinct variety of English. The study is corpus-based. This allows the researcher to use actual incidences of speech from contemporary speakers of Southern Irish English, thus allowing for an empirical approach to the research whereby physical evidence rather than intuition is the basis for the findings. The corpus to be used, The Limerick Corpus of Irish English, containing one million words of transcribed contemporary Southern Irish English casual conversation, is sufficiently large to verify the contemporary usage of most of the patterns of Southern Irish English. The study is limited to cer...

A novel high quality efficient algorithm for time-scale modification of speech
(1999)
Lawlor, Bob; Fagan, A.D.
Abstract:
We present a novel efficient algorithm for time-scale modification (TSM) of speech which gives output quality equal to that of a conventional TSM algorithm, but having computational load an order of magnitude less. The algorithm presented uses a fixed length rectangular stepping window and a simple peak alignment criterion to track the local natural scaling factor and adapt the window step size. The desired TSM factor is realised by the appropriate number of applications of the constantly varying local natural scaling factor. The local natural scaling factor estimate is updated at sub-pitch period intervals giving accurate pitch tracking and high quality in the output scaled signal.

A Study of Accomodation of Prosodic and Temporal Features in Spoken Dialogues in View of Speech Technology Applications
(2010)
Kousidis, Spyridon, [Thesis]
Abstract:
Inter-speaker accommodation is a well-known property of human speech and human interaction in general. Broadly it refers to the behavioural patterns of two (or more) interactants and the effect of the (verbal and non-verbal) behaviour of each to that of the other(s). Implementation of thisbehavior in spoken dialogue systems is desirable as an improvement on the naturalness of humanmachine interaction. However, traditional qualitative descriptions of accommodation phenomena do not provide sufficient information for such an implementation. Therefore, a quantitativedescription of inter-speaker accommodation is required. This thesis proposes a methodology of monitoring accommodation during a human or humancomputer dialogue, which utilizes a moving average filter over sequential frames for each speaker. These frames are time-aligned across the speakers, hence the name Time Aligned Moving Average (TAMA). Analysis of spontaneous human dialogue recordings by means of the TAMA methodology re...

Adult speakers' tongue-palate contact patterns for bilabial stops within complex clusters
(2009)
Zharkova, Natalia; Schaeffler, Sonja; Gibbon, Fiona E.
Abstract:
Previous studies using Electropalatography (EPG) have shown that individuals with speech disorders sometimes produce articulation errors that affect bilabial targets, but currently there is limited normative data available. In this study, EPG and acoustic data were recorded during complex word final /sps/ clusters spoken by 20 normal adults. A total contact (TC) index measured amount of tongue-palate contact during clusters in words such as 'crisps'. Bilabial closure was inferred from the acoustic signal. The TC profiles indicated that normal adults hold their tongues in a steady /s/-like position throughout the cluster; most speakers (85%, n=17) had no significant difference in TC values during bilabial closure compared to flanking fricatives. The results are interpreted as showing that normal speakers produce double bilabial-alveolar articulations for /p/ in these clusters. Although steady state TC profiles were typical of the group, absolute TC values varied considerabl...

Abstract:
The 9th International Conference on Speech Communication and Technology (Interspeech 2005), Lisbon, Portugal, September, 2005
This paper presents a novel agent-based framework for investigating speech recognition which combines statistical data and explicit phonological knowledge in order to explore strategies aimed at augmenting the performance of automatic speech recognition (ASR) systems. This line of research is motivated by a desire to provide solutions to some of the more notable problems encountered, including in particular the problematic phenomena of coarticulation, underspecified input, and out-ofvocabulary items. This research also seeks to promote the use of deliberative reasoning agents in the speech and natural language processing arenas.

An experiment in audio classification from compressed data
(2004)
Jarina, Roman; O'Connor, Noel E.; Murphy, Noel; Marlow, Seán
Abstract:
In this paper we present an algorithm for automatic classification of sound into speech, instrumental sound/ music and silence. The method is based on thresholding of features derived from the modulation envelope of the frequency limited audio signal. Four characteristics are examined for discrimination: the occurrence and duration of energy peaks, rhythmic content and the level of harmonic content. The proposed algorithm allows classification directly on MPEG-1 audio bitstreams. The performance of the classifier was evaluated on TRECVID test data. The test results are above-average among all TREC participants. The approaches adopted by other research groups participating in TREC are also discussed.

Are the Irish norms for the DEAP valid for a local population?
(2014)
Barrett, Katie
Abstract:
Background: Standardised assessments provide a means of objectively identifying and diagnosing speech sound disorders to determine eligibility for speech and language services (Broomfield and Dodd 2004; Dodd et al. 2009; Skahan et al. 2007). Normative data is provided for comparison with a clinical population; discrepancies in this comparison may indicate a speech sound disorder. The Diagnostic Evaluation of Articulation and Phonology (DEAP) is a standardised assessment that allows for the identification of children with speech sound disorders. The Irish standardisation of the DEAP was based two geographical areas- Dublin and Galway. Consequently it may not be representative of Irish children in other areas. Objectives: To determine whether normative data for the Irish standardisation of the DEAP is valid for children in Limerick .To determine whether social economic status (SES) affects the rate of phonological acquisition. Methods: 56 typically developing children aged between 3.0...

Articulating networked citizenship on the Russian internet: a case for competing affordances

Articulating networked citizenship on the Russian internet: a case for competing affordances
(2020)
Lokot, Tetyana
Abstract:
The Russian government’s crackdown on free speech online has seen social media users jailed and fined for publishing critical content. Digital rights activists have cautioned Russians to delete their accounts on platforms that cooperate with law enforcement, but also have advocated for the use of privacy and secure tools. How do these actions inform emergent articulations of networked citizenship in Russia? Using activity reports published online by the state Internet regulator and two digital activist groups, I conduct a narrative analysis of how both parties interpret networked citizenship. I find that the networked authoritarian Russian state embraces the ideal of the dutiful networked citizen online as visible, vulnerable, and controlled, exploiting the melding of public and private aspects of networked publics. Instead, Russian digital rights activists advocate for a self-actualizing networked citizen who exercises agency online by becoming less visible, often ephemeral, and th...

Be safe or be seen? How Russian activists negotiate visibility and security in online resistance practices
(2018)
Lokot, Tetyana
Abstract:
This paper examines how Russian opposition activists negotiate online visibility—their own and that of their messages and campaigns—and the security concerns brought on by the pervasive digital surveillance that the state resorts to in order to reinstate its control over the online discursive space. By examining the internet-based presence and activity of the members of Alexey Navalny’s FBK (Anti-Corruption Foundation) and other opposition activists, the paper traces connections between everyday security practices that these activists engage in online and the resistance tactics and repertoires they enact in an environment where the free and open exchange of information on the Russian internet is becoming increasingly difficult. The analysis finds that Russian opposition activists place a high value on digital, media, and security literacy and that navigating the internet using security tools and protocols such as VPN, two-phase authentication, and encrypted messaging is increasingly...

Benchmarking Classification Models for Emotion Recognition in Natural Speech: a Multi-Corporal Study
(2011)
Tarasov, Alexey; Delany, Sarah Jane
Abstract:
A significant amount of the research on automatic emotion recognition from speech focuses on acted speech that is produced by professional actors. This approach often leads to overoptimistic results as the recognition of emotion in real-life conditions is more challenging due the propensity of mixed and less intense emotions in natural speech. The paper presents an empirical study of the most widely used classifiers in the domain of emotion recognition from speech, across multiple non-actedemotional speech corpora. The results indicate that Support Vector Machines have the best performance and that they along with Multi-Layer Perceptron networks and k-nearest neighbour classifiers perform significantly better (using the appropriate statistical tests) than decision trees, Naıve Bayes classifiers and Radial Basis Function networks.

CATALISE: A multinational and multidisciplinary Delphi consensus study. Identifying language impairments in children
(2016)
Bishop, Dorothy V. M.; Snowling, Margaret J.; Thompson, Paul A.; Greenhalgh, Trisha; Catalise consortium
Abstract:
Delayed or impaired language development is a common developmental concern, yet there is little agreement about the criteria used to identify and classify language impairments in children. Children's language difficulties are at the interface between education, medicine and the allied professions, who may all adopt different approaches to conceptualising them. Our goal in this study was to use an online Delphi technique to see whether it was possible to achieve consensus among professionals on appropriate criteria for identifying children who might benefit from specialist services. We recruited a panel of 59 experts representing ten disciplines (including education, psychology, speech-language therapy/pathology, paediatrics and child psychiatry) from English-speaking countries (Australia, Canada, Ireland, New Zealand, United Kingdom and USA). The starting point for round 1 was a set of 46 statements based on articles and commentaries in a special issue of a journal focusing on ...

Censored: Whistleblowers and impossible speech
(2019)
Kenny, Kate
Abstract:
What happens to a person who speaks out about corruption in their organization, and finds themselves excluded from their profession? In this article, I argue that whistleblowers experience exclusions because they have engaged in â impossible speechâ , that is, a speech act considered to be unacceptable or illegitimate. Drawing on Butlerâ s theories of recognition and censorship, I show how norms of acceptable speech working through recruitment practices, alongside the actions of colleagues, can regulate subject positions and ultimately â un-doâ whistleblowers. In turn, they construct boundaries against â unethicalâ others who have not spoken out. Based on in-depth empirical research on financial sector whistleblowers, the article departs from existing literature that depicts the excluded whistleblower as a passive victim â a hollow stereotype. It contributes to organization studies in a number of ways. To debates on Butlerâ s recognition-based critique of subjectivity in...

Convergence in Human Dialogues Time Series Analysis of Acoustic Feature
(2009)
Kousidis, Spyros; Dorran, David; Mcdonnell, Ciaran; Coyle, Eugene
Abstract:
Convergence of acoustic/prosodic (a/p) features between two speakers is a well-known property of human dialogue. It has been suggested that this particular aspect of human interaction should be implemented in spoken dialogue systems, so that they can be perceived as more “humanlike”. This paper presents a quantitative analysis method that can provide information required for modeling the phenomenon of convergence. The analysis is a combination of TAMA, a previously introduced data extraction method, and bivariate time series analysis. Results show significant correlation of a/p features between speaker dyads in the recorded dialogues analyzed, and indicate a significant,amount of feedback, which a statistical verification of bidirectional convergence.

Diagnosing language impairment in bilinguals: professional experience and perception
(2012)
O'Toole, Ciara; Hickey, Tina M.
Abstract:
Diagnosing specific language impairment (SLI) in monolingual children is a complex task, with some controversy regarding criteria. Diagnosis of SLI in bilinguals is made more complex by the lack of standardized assessments and poor understanding of clinical markers in languages other than English. There is an added complexity when one of the languages being acquired is an endangered one, where the domains of use and input are restricted, and where input is affected by convergence with the majority language. This article explores the challenge facing speech and language therapists and psychologists in diagnosing SLI in bilingual children acquiring Irish and English. Six speech and language therapists and four psychologists took part in semi-structured interviews exploring the impact of the bilingual environment, the nature of bilingual language impairment, current practices and the needs of these children. Thematic analysis was carried out and here three of the main themes emerging i...

Down the (white) rabbit hole: the extreme right and online recommender systems

O'Callaghan, Derek; Greene, Derek; Conway, Maura; Carthy, Joe; Cunningham, Padraig
Abstract:
In addition to hosting user-generated video content, YouTube provides recommendation services, where sets of related and recommended videos are presented to users, based on factors such as co-visitation count and prior viewing history. This article is specifically concerned with extreme right (ER) video content, portions of which contravene hate laws and are thus illegal in certain countries, which are recommended by YouTube to some users. We develop a categorization of this content based on various schema found in a selection of academic literature on the ER, which is then used to demonstrate the political articulations of YouTube’s recommender system, particularly the narrowing of the range of content to which users are exposed and the potential impacts of this. For this purpose, we use two data sets of English and German language ER YouTube channels, along with channels suggested by YouTube’s related video service. A process is observable whereby users accessing an ER YouTube vid...

Emotional Speech Corpus Construction, Annotation and Distribution
(2008)
Vaughan, Brian; Cullen, Charlie; Kousidis, Spyros; McAuley, John
Abstract:
This paper details a process of creating an emotional speech corpus by collecting natural emotional speech assets, analysisng and tagging them (for certain acoustic and linguistic features) and annotating them within an on-line database. The definition of specific metadata for use with an emotional speech corpus is crucial, in that poorly (or inaccurately) annotated assets are of little use in analysis. This problem is compounded by the lack of standardisation for speech corpora, particularly in relation to emotion content. The ISLE Metadata Initiative (IMDI) is the only cohesive attempt at corpus metadata standardisation performed thus far. Although not a comprehensive (or universally adopted) standard, IMDI represents the only current standard for speech corpus metadata available. The adoption of the IMDI standard allows the corpus to be re-used and expanded, in a clear and structured manner, ensuring its re-usability and usefulness as well as addressing issues of data-sparsitiy w...

Abstract:
The everyday lives of children with disabilities are not well understood, with few studies exploring how participation in everyday life is conceptualized and given meaning. The overall aims of this study were, first, to explore parental views of their children's participation and, second, to identify barriers and facilitators in relation to participation in everyday activities. A qualitative research strategy was adopted, whereby parents of children with Down syndrome (DS) aged 6-12 years were selected using purposive sampling. Five interviews with seven participants were audio-recorded and analysed using a framework approach whereby the overall research aims guided the analysis. Analysis of the data identified two main themes and seven sub-themes. The first theme was the value of participation. Parents reported that through participation in activities, their children developed skills that in turn enhanced their well-being and sense of belonging. The second theme was barriers a...
