1 | 2009 | Sustainability Of Research And Development: A Case Of Successful Technology Transfer In Spoken Language Technology Click to View Abstract We share our experience on how to establish sustainable research and development based on successful collaborative research between the Local Language Speech Technology Initiative of UK and Kenyan partner - Teknobyte Ltd. Starting in 2003 when we embarked on spoken language technology development, technology and expertise were successfully transferred to the Kenyan partners, culminating in the launch in April 2008 of the National Farmers Information Service (NAFIS), a voice service accessed over the phone which offers a wide range of information in Kiswahili or Kenyan English to supplement the existing agricultural extension services. | ||

7 | 2008 | Experience With Developing And Deploying An Agricultural Information System Using Spoken Language Technology In Kenya Click to View Abstract We describe the progress of the Local Language Speech Technology Initiative in Kenya, where since starting in 2003, technology and expertise have been successfully transferred to the Kenyan partners, culminating in the launch of the National Farmers Information Service (NAFIS) in April 2008. NAFIS is primarily a voice service accessed over the phone and offers a wide range of information in Kiswahili or Kenyan English, supplementing the existing agricultural extension services. | ||

10 | 2005 | Development Of A Kiswahili Text To Speech System Click to View Abstract This paper discusses how a concatenative Kiswahili Text to Speech System (TTS) was developed based on the Festival Unit Selection Speech Synthesiser. It explains how important Kiswahili linguistic features such as phones, stress and intonation were modelled as inputs to the Festival engine. It also discusses the design, recording and segmentation of the speech database, beginning with text corpus collection and transcription. The choice of the speaker, which is crucial to realising a good TTS is discussed and also how the system was tested. | ||
11 | 2004 | Design Of Speech Database For Unit Selection In Kiswahili Text To Speech System Click to View Abstract When developing a Concatenative Text to Speech System [1, 3, 4] (i.e. a form of synthesis where waveforms are created by concatenating parts of natural speech recorded from humans) it is necessary that all the acoustically and perceptually significant sound variations (allophones) in the language are recorded so that they are played back each time the system synthesises speech. Improvement on the system is made by assuming that co-articulation (mutual influence between adjoining sounds) does not extend beyond phone-phone boundary [1]. In this case all possible phone-phone combinations are read and recorded. Each unit of the two phone combination is referred to as the diphone. Synthesis is then based on concatenation of the diphones thus taking care of the overlap in the phone-phone boundary. An even better system can be realised when each diphone is captured within the context of several words and synthesis carried out by using the best selection from the recorded words. It is clear then that this procedure must use proper selection of the sentences from which the diphones are to be captured. In other words, such sentences must be phonetically balanced; implying that they must have the same phone distribution as used entirely in the language. | ||
12 | 2004 | Some Essential Features In Developing A Text To Speech System In Kiswahili Click to View Abstract This paper discusses the important aspects to be considered when developing A Text To Speech System (TTS) in Kiswahili. These include linguistic features such as the phoneset, stresses and intonation. The choice of the standard dialect is also discussed. TTS features such as the text normalisation and the lexicon for Kiswahili are discussed. | ||

14 | 1994 | Application Of Field Calculations In Optimization Of Insulator Designs Click to View Abstract When an insulator is placed in an electrode gap, its surface charge field distorts the geometric field, leading to a flashover at a voltage value dependent on the degree of the gap field distortion. This paper reports on studies conducted to determine the relationship between flashover voltages and electric filed distribution along solid insulator surfaces. The surface electric field distribution along different insulator profiles was determined using the Finite-Difference method, and the flashover of the actual profile model measured. The obtained results show that each profile had a peak surface electric field and the higher the peak value, the lower the flashover voltage. The correlation curve for peak electric field and flashover voltage was developed using a curve fitting technique based on the Nelder-Mead simplex algorithm. | ||
