Development of a spoken dialogue system operating in Afrikaans, South African English and Xhosa
We present a spoken dialogue system operating in Afrikaans, South African English and Xhosa. The architecture of the overall system as well as the speech recognition, natural language understanding, dialogue control and speech synthesis subcomponents are described. Prototype systems operating in each of the three languages have been developed and subjected to user trials. The performance achieved by these systems is compared, giving some insight into the use of each language in spoken dialogue systems.
