Who we are

The CSIR’s Voice Computing Research Group studies the way in which speech- and language-related technologies can be created and applied to benefit the people of South Africa. South Africa is a multilingual country with 11 official languages, requiring unique technology solutions like iSinkwe to accommodate the diversity of languages.
