Automatic Speech Recognition (ASR) research has been primarily focused towards large-scale systems and industry, while other areas that require attention are often over-looked by researchers. For this reason, this research looked at automatic speech recognition at the consumer level. Many individual consumers will purchase and use automatic software recognition for a different purpose than that of the military or commercial industries, such as telecommunications. Consumers who purchase the software for personal use will mainly use ASR for dictation of correspondences and documents. Two ASR dictation software packages were used to conduct the study. The research examined the relationships between (1) speech recognition software training and word accuracy, (2) error-correction time by the user and word accuracy, and (3) correspondence type and word accuracy. The correspondences evaluated were those that resemble Personal, Business, and Technical Correspondences. Word accuracy was assessed after initial system training, five minutes of error-correction time, and ten minutes of error-correction time. Results indicated that word recognition accuracy achieved does affect user satisfaction. It was also found that with increased error-correction time, word accuracy results improved. Additionally, the results found that Personal Correspondence achieved the highest mean word accuracy rate for both systems and that Dragon Systems achieved the highest mean word accuracy recognition for the Correspondences explored in this research. Results were discussed in terms of subjective and objective measures, advantages and disadvantages of speech input, and design recommendations were provided. / Master of Science

This study verifies previous econometric research which found that spreadsheet prices, when adjusted for quality improvement, decline over the period 1986-1993. New econometric work is presented for prepackaged word processing software. Using objective criteria for variable selection, the model yields declining quality-adjusted prices for word processing software over the period 1985-1994. / Master of Arts

The purpose of the present study was to tease apart the paralinguistic from the linguistic aspects of infants' perception of infant-directed (ID) speech. Several studies have shown that infants beginning at a few days after birth discriminate native from nonnative speech and can discriminate specific contours (rising, falling, rising-falling) in ID speech. Some studies have also indicated that infants at 4.5 months of age prefer their own name over other names but at 6 months of age, fail to prefer a sentence with their own name embedded in it. Using a discrimination procedure, the current study investigated whether 6-month-old infants could detect a change in contour and/or a change in words when listening to ID utterances. Results indicated that 6-month-old infants detected both a contour and a word change. From these results, it is argued that as has been shown in other experiments, infants are extremely sensitive to subtle changes in speech. Furthermore, ID speech appears to facilitate infants' ability to discriminate small changes in ID speech (both linguistic and paralinguistic). It is suggested that future studies investigate more discrete changes in speech samples and a replication of this research with adult-directed (AD) speech. / Master of Science

The purpose of this study was to determine how word processing is being utilized in businesses with word processing systems in the Richmond metropolitan area. No data are available about the current implementation of word processing in a major metropolitan area in Virginia. This study was undertaken in order to add to the knowledge base that already exists about the implementation of word processing in other areas. Fifty word processing managers and supervisors representing the Word Processing Association of Richmond, with members from the metropolitan area, comprised the study population. The study addressed the following research questions: 1. How is the word processing concept being implemented in businesses with word processing systems in the Richmond metropolitan area? 2. What employment patterns exist in businesses with word processing systems in the Richmond Metropolitan area? 3. What plans do businesses with word processing systems in the Richmond Metropolitan area, have for expansion of the word processing system and for the application· of emerging technologies? A nine-part instrument was used to collect the data for the study. The instrument was validated by a panel of experts and was pretested before the data were collected. The Richmond metropolitan area was selected as the survey site because it contains a high concentration of organizations that are likely to benefit from the implementation of word processing. The Word Processing Association of Richmond was selected as the survey population because this group is representative of organizations utilizing word processing in the area. The researcher conducted fifty personal interviews between May and June, 1981. The major findings of this study follow: 1. The word processing employment market is expanding. Organizations are acquiring additional equipment, are planning to support more principals, and are creating additional positions for word processing personnel. 2. Word processing systems are generally centralized, are responsible for all correspondence tasks, operate in a modular office layout, and are managed by both a word processing manager and a supervisor. 3. Although the documents most frequently processed are memos/ letters, other applications are also being processed; statistical, medical, legal, and textual documents; address lists; and forms design and completion. 4. Longhand, machine dictation, typed drafts, and optical character recognition are used as sources of input in word processing. The use of each input mode varies with the type of document and the organizational preference. 5. The CRT display system is the most frequently used type of equipment and projections indicate that it will be the most frequently used type of equipment in five years. Blind standalones, online display systems, shared-logic systems, and photocomposition systems are also in use. 6. Emerging office systems technologies are in use and their use will expand. The integration of word processing and data processing will increase. The use of shared-logic, intelligent copiers, electronic mail, desk-top terminals for principals, OCR, micrographics, and telecommunication will increase. / Ed. D.

It is well established in developmental science that 14-month-old infants have significant difficulty associating pairs of objects with pairs of words that differ by a single phoneme (i.e., minimal pairs). This study used a traditional switch procedure in two experimental conditions (i.e., no face versus face with shifting gaze) to habituate infants with objects and minimal pair labels. Additionally, infants participated in a joint attention task and parents completed questionnaires related to family demographics and infant health and development, to compare to switch task performance. It was expected that infants' difficulty with minimal pair associative learning would be replicated in the no face condition. It was also predicted that the addition of a female face and the cues it could provide would abate the challenge that this task typically presents. As a group, infants' performances in the two conditions were not significantly different from each other and were not significantly different from chance. Analyses explored the relations between switch performance, joint attention task performance and questionnaire data, resulting in a significant correlation between performance in the face condition of the switch task and number of ear infections (r = .62, p < .05). Taken together, the addition of a female face with shifting gaze to a challenging word learning task does not sufficiently attenuate the cognitive load created by the task. The implications of these results are discussed further. / Master of Science

Two experiments were conducted to examine parameters of the process of word recognition. In both experiments, subjects were required to guess the identity of words from which letters were exposed. In the first experiment, independent variables were frequency of occurrence in the language of stimulus words, number of letters selected from the words, and the position of the letters within the words. All three variables yielded significant effects. Connotative meaning of the stimulus words and the number of letters exposed from the beginning of the words were varied in the second experiment. As in the first experiment, the effect due to number of letters was significant. Connotative meaning, however, did not contribute significantly to subjects’ recognition latencies. / Thesis / Master of Arts (MA)

Published Article / This study evaluated the difficulty, in terms of usability, of upgrading from one version of a word processor user interface (Microsoft Word 2003) to another (2007). Laboratory-based usability testing involving 23 participants, who had never used Microsoft Word 2007 before, was conducted. All participants used the two versions in a repeated-measures experimental design. A Tobii 1750 Eye Tracker was used for screen recordings during testing. Participants were also required to fill in user satisfaction questionnaires. Results from the usability test showed that, in terms of usability, migrating from an original interface to a completely changed user interface is not easy.

This thesis explores and examines the concept of the threefold Word of God in the theology of Karl Barth, particularly the third form of the Word of God, the gospel proclamation, and argues that this tertiary form of the Word of God is central to Barth’s own theology of the church. This thesis argues that Karl Barth revised the concept of the threefold Word of God in the later volumes of the Church Dogmatics, but did not seek to reject the concept nor reject Christ’s presence and God’s speech in the gospel declaration and in the life of the Christian community. This thesis argues that the threefold Word of God is a crucial element in Karl Barth’s vision of the church and an important theme for the whole of his theological project. Disregarded by the field of Barth studies and rejected by modern ecclesiologists, Barth’s description of the gospel declaration and its central role in the life together of the Christian community offers an important ecclesiological alternative to carry forward for both Reformed theology and modern ecclesiology. This dissertation makes three significant contributions. First, this thesis is the first of its kind to engage comprehensively with Karl Barth’s concept of the threefold Word of God and to make clear its later revision. Second, this dissertation offers a review of the contemporary scholarly literature related to Barth’s revision of the threefold Word of God, and addresses the theological and ecclesiological implications of this revision. Third, this dissertation makes a contribution to the fields of Barth studies and contemporary ecclesiology by arguing for the central place of the third form of the Word of God in Karl Barth’s conception of the Christian community.

Thesis (MBA (Business Management))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: Word-of-mouth is fluid and happening everywhere. Networks are invisible and sensitive to organisational behaviour. The post-modern consumer is sceptical of advertising messages. Friends' advice is trusted more. People love to be entertained and for a story to travel it needs to be sticky i.e. have simplicity, credibility and value. The product or message must be relevant and appropriate to their lives. Influencers exist in every product category and marketers could utilise them authentically to infiltrate network hubs. However, a contagious product is needed from a trusted, loved company with a solid reputation first before any buzz or referrals could commence. Communication between the company and the subject ought to be ongoing and personal. Companies must not just aim to please, but exceed expectations in an innovative way to gain attention. A clear differentiation from competitors stated in an unconventional and memorable way is a potent combination to make an impact and be remembered. Although the black middle class presents itself as an ever-growing goldmine, this buoyant part of the South African market is still underplayed and sometimes ignored by marketers. They are indeed different from the white middle class due to their frame of reference and the context of their background and should be approached differently in a marketing sense when truly gaining insight into their attitudes, values and belief systems. Coming from a tripartheid background, black middle class women are gaining economic and influential ground by the day. Word-of-mouth is an integral part of their life and network culture, especially standing with one foot in a Western world and another in their traditional African roots and culture, thus trusted advice from relevant sources is now more needed than ever. Understanding her dreams, being able to catch the fleeting moments which provide her motivation and collaborating with her is imperative for marketers to understand if their product or brand wants to be taken with her on her success journey. As she embraces technology more and gains access to the virtual world, creating and upholding digital interaction with her becomes increasingly important. In trying economic times, conspicuous consumption by the black middle class consumer is being put on the backburner, yet it would still remain a priority for this segment of the market for years to come as the quest towards self-actualisation is ongoing. Brands must be educated to follow up on their word-of-mouth campaigns, and provide support and appreciation to their pool of network influencers. Although measuring word-of-mouth is difficult it could be measured by objectives like sales-targets, with online activity being much easier to measure. In trying economic times an insightful and impactful word-of-mouth campaign could have a much greater return on investment than utilising the same old traditional media approaches. Media planning should commence from the customer‘s point of view and not from the company‘s point of view. By doing this the customer is treated like a true stakeholder of the company. When doing media planning, historic ways of making target market contact should be ignored and planning should be done on a completely clean slate thus to enable media planners and marketers to think innovatively. By incorporating these healthy media planning practices the door is opened for a possible word-of-mouth initiative to commence and thus a competitive advantage could be gained. The purpose of this literature study, which includes expert interviews, is to explore current word-of-mouth literature and tools available in light of globalisation enabling virtual communities and overlaying this with psychographical models available in South Africa, particularly focusing on the black middle class woman‘s evolvement sustaining cultural roots and traditional networks yet opening up to a changing media environment. The research question for this study thus is: How can brands and organisations utilise word-of-mouth marketing to reach and resonate with the modern emerging black middle class woman in South Africa today? / AFRIKAANSE OPSOMMING: Word-of-mouth is vloeiend en vind orals om ons plaas. Netwerke van mense is onsigbaar en sensitief vir die gedrag van enige onderneming. Die postmoderne verbruiker staan skepties teenoor advertensieboodskappe. Vriende se advies is meer betroubaar. Mense hou daarvan om vermaak te word en vir ʼn storie om te versprei is ʼn tipe volhoubaarheid nodig, dus die storie moet eenvoudig wees en kredietwaardigheid hê. Die produk of boodskap moet op hul lewens van toepassing wees en aldus relevansie hê. Die kategorie waarin elke produk geplaas word, huisves invloedryke verbruikers en sodoende kan bemarkers op 'n natuurlike wyse bestaande netwerke binnedring. ʼn Onderneming met ʼn eerbare reputasie wat geliefd en betroubaar is moet ʼn opwindende of opspraakwekkende produk kan lewer alvorens enige gonsing of reaksie in die mark kan geskied. Kommunikasie tussen die onderneming en die invloedryke persoon in eersgenoemde se teikenmarknetwerk moet deurgaans op persoonlike vlak geskied. Ondernemings moet poog om nie net aan hul verbruikers se verwagtinge te voldoen nie, maar om dit te oortref op 'n innoverende manier wat die aandag trek. ʼn Duidelike onderskeid tussen mededingers moet op ʼn onkonvensionele en indrukwekkende wyse plaasvind om sodoende ʼn volhoubare indruk te maak. Alhoewel die swart middelklas ʼn vinnig-groeiende goudmyn is, word hierdie uiters winsgewende sektor van die Suid-Afrikaanse mark steeds onderskat en somtyds deur bemarkers geïgnoreer. Die swart middelklas is immers verskillend van die wit middelklas as gevolg van hulle verwysingsraamwerk en agtergrond en moet dus anders in ʼn bemarkingskonteks benader word. Te meer gesien in die lig van hul opvattinge, waardes en geloofsoortuigings. Swart middelklas vroue, komende van ʼn drie-dubbele apartheids-agtergrond, styg in rasse skrede op ekonomiese vlak uit en raak veral invloedryk op vele gebiede. Hoorsê of oorvertellings is ʼn integrale deel van hulle lewens- en netwerkkultuur, veral as in ag geneem word dat sy met een voet in die Westerste kultuur en die ander gewortel in haar tradisionele Afrika kultuur staan. Daarom is vertrouenswaardige advies van relevante bronne nou meer nodig as ooit. Indien bemarkers daarin wil slaag dat sy hul produk of handelsmerk steeds bly gebruik soos sy meer suksesvol raak, moet hulle haar drome en die vlietende oomblikke wat haar motiveer verstaan en ook met haar bande smee. Soos sy meer vertroud raak met tegnologie en toegang verkry tot die virtuele wêreld, sal die skepping en behoud van digitale interaksie met haar al hoe belangriker word. Alhoewel duidelik waarneembare handelsmerkverbruik deur die swart middelklas tydens moeilike ekonomiese tye verflou of afplat, sal dit tog vir diesulkes nog jare 'n prioriteit bly soos wat hul konstante strewe na selfaktualisering daagliks aanhou groei. Handelsmerke moet daarna streef om gedurende word-of-mouth bemarkingsveldtogte sake konstant te bly opvolg. Hulle moet ook hul waardering toon aan diegene wat die grootste invloed het op ander in hul geïdentifiseerde netwerke van verbruikers en hulle aldus ondersteuning bied. Alhoewel die meting van word-of-mouth bemarking moeilik is, kan meting wel plaasvind deur doelwitte soos beoogde verkoopsyfers daar te stel. Aanlyn aktiwiteite is aansienlik makliker om te meet. Ondernemings kan heel moontlik ʼn groter verdienste-teenoor-investeringsmarge verkry, die resessie in ag genome, deur eerder indrukwekkende word-of-mouth veldtogte, geskoei op goeie markinsig te gebruik, as om terug te val op dieselfde ou tradisionele mediabenaderings. Die doel van hierdie literatuurstudie, wat ook onderhoude met kenners insluit, is om huidige word-of-mouth tegnieke en beskikbare literatuur te ontplooi teen ʼn agtergrond van globalisering wat skepping van virtuele gemeenskappe tot gevolg het. Hierdie inligting word dan gekorreleer met verskeie psigografiese modelle van die Suid-Afrikaanse swart middelklas mark. Hierdie studie fokus ook noukeurig op die vooruitgang van die swart middelklas vrou. Alhoewel sy nog haar tradisionele sosiale netwerke en kultuurgrondslag behou, stel sy haarself tog oop vir ʼn vinnig veranderende media-omgewing. Die navorsingsvraag van hierdie studie is dus: Hoe kan handelsmerke en ondernemings “word-of-mouth” bemarking gebruik om die ontluikende, moderne swart middelklasvrou in Suid-Afrika effektief te bereik en by haar aanklank te vind?
