We describe the design and development processes that were undertaken in order to develop the corpus, and report on associated materials such as orthographic transcriptions and pronunciation dictionaries that were released as part of the corpus. In order to benchmark speech recognition performance on the corpus, we have also developed both phone-recognition and word-recognition systems for all eleven languages; we nd that high accuracies can be achieved for these speaker-independent but vocabulary-dependent recognition tasks in all languages.enAutomatic Speech RecognitionASRText-to speechTTSSouth African languagesSpoken language technologiesUnder-resources languagesConference PresentationBarnard, E., Davel, M., Van Heerden, C., De Wet, F., & Badenhorst, J.
