    Increased diphone recognition for an Afrikaans TTS system
    (2004) Rousseau, Francois; Mashao, Daniel
    In this paper we discuss the implementation of an Afrikaans TTS system that is based on diphones. Using diphones makes the system flexible but presents other challenges. A previous effort to design an Afrikaans TTS system was done by SUN. They implemented a TTS system based on full words. A full word based TTS system produces more natural sounding speech than when the system is designed using other techniques. The disadvantage of using full words is that it lacks flexibility. The baseline system was build using the Festival Speech Synthesis System. Problems occurred in the baseline due to the mislabeling of diphones and the diphone index. The system was improved by manually labeling the diphones using Wavesurfer, and by changing the diphone index. Wavelength comparison tests were done on the diphone index to show how much of the diphones are recognized during synthesis. For the diphones tested results show an average improvement of 38% in the recognition of diphones compared to the baseline. These improvements improve the overall quality of the system.

    Writing Your World Week 2 Video 3 - Nelson Mandela: Terrorist or Freedom Fighter
    (2019-06-01) Hunma, Aditi; Nomdo, Gideon
    This video focuses on Nelson Mandela. The video touches on the apartheid policy that led to the creation of the homelands (TBVC states). It then touches on how Mandela originated from one of the TBVC states and then how his actions and identity had him labelled as a terrorist. The video then discusses Mandela's experience and image during apartheid. The video also contrasts Mandela's identity in history and currently. The video then highlights the importance of context when it comes to one's identity and the sense of individuality. This is video 3/10 in week 2 of the Writing your World course.
