Category-based phoneme-to-grapheme transliteration
(International Speech Communication Association ( ISCA ), 2013)Grapheme-based speech recognition systems are faster to develop but typically do not reach the same level of performance as phoneme-based systems. In this paper we introduce a technique for improving the performance of ... -
The Challenge: Quality Enhancement in Teaching– How do We Know We are Making Progress?
(IACSIT Press, 2014)In 2014 the Council for Higher Education in South Africa launched a national Quality Enhancement Project (QEP). The aim of the project is to improve student success both at individual Higher Education Institutions and in ... -
Characterizing volunteers in sporting mega events: the case of the Fifa soccer world cup in South Africa
(The Global Business and Technology Association, 2013)Mega sporting events need a number of activities to be properly coordinated if they are to be successful. These events require large numbers of human resources and invariably reliance is heavily on volunteers. Essentially, ... -
Communication between information system development team members from different cultural contexts: a case study
(IADIS Press, 2013)The aim of this study was to investigate how communication is affected by the different cultural contexts of information system development (ISD) team members in order to achieve ISD project results. The study investigated ... -
Comparing grapheme-based and phoneme-based speech recognition for Afrikaans
(PRASA, 2012)This paper compares the recognition accuracy of a phoneme-based automatic speech recognition system with that of a grapheme-based system, using Afrikaans as case study. The first system is developed using a conventional ... -
A comparison of additive and multiplicative functions for water poverty index calculation
(International Business Information Management Association, 2013)The aim of this research is to quantify the difference in the water poverty index when calculated with the additive function compared to the multiplicative function. It is calculated and compared for the three towns that ... -
Context-dependent modelling of English vowels in Sepedi code-switched speech
(Pattern recognition association of South Africa (PRASA), 2012)When modelling code-switched speech (utterances that contain a mixture of languages), the embedded language often contains phones not found in the matrix language. These are typically dealt with by either extending the ... -
Correlation between rapid learnability and user preference in IVR systems for developing regions
