FOUR young scientists are set to showcase their award-winning innovations at the World Innovative Science Project Olympiad (WISPO) in Bali, Indonesia.
The learners, all Gold medal winners at the Eskom Expo International Science Fair (ISF), include Dzunisa Chauke, in Grade 12 at Khanyisa Education Centre (Mopani); Milla Vorster, in Grade 11 at Curro Durbanville (Stellenbosch); Ismaail (Miles) Hassen, in Grade 11 at Greenside High School (Johannesburg); and Albertus Willem (Wium) van Niekerk, in Grade 10 at Paul Roos Gymnasium (Stellenbosch).
The learners will travel under the guidance of delegation leader Jane Wasonga, Eskom Expo Johannesburg Regional Science Fair director.
The Olympiad is set to take place from December 10-13.
Chauke will showcase his research project entitled “Synthetic vs non-synthetic voices”. He developed a fast, offline and highly accurate voice-classification system capable of distinguishing human voices from Al-generated synthetic audio. Using MFCCs, chroma analysis and a Random Forest model, his system addresses urgent cybersecurity risks linked to AI-driven impersonation and fraud.
