Why don’t other test providers use automatic speech scoring, can it really be trusted?
The system Pearson uses for automatically scoring speech is a proprietary and patented system not available to other companies. Versant has been operational for more than 10 years. The system is now available for several languages (English, Spanish, Dutch) and systems for more languages are under development (Arabic, French, German, Japanese). Versant has been used by hundreds of educational and commercial institutions worldwide. It is trusted by these institutions and also by governmental bodies (US Department of Homeland Security, Immigration and Naturalization Service in the Netherlands).
