Patented Ordinate® Technology
The Versant testing system is based on years of research in speech processing, statistical modeling, linguistics, latent semantic analysis, and testing theory.
The Versant testing system, based on the patented Ordinate® technology, uses a speech
processing system that is specifically designed to analyze speech from native and
non-native speakers of the language tested. In addition to recognizing words, the system
also locates and evaluates relevant segments, syllables, and phrases in speech. The
Versant testing system then uses statistical modeling techniques to assess the spoken
Independent studies have shown that Versant tests are objective, and produce measures of score reliability which exceed those of many standard human-rated tests, including one-on-one oral proficiency interviews. Using criteria developed by expert linguists, the Versant testing system scores candidate responses to test items, which have been validated with reference to human judgments of proficiency, fluency, and pronunciation.
