The patented Versant testing system is based on years of research in speech processing, statistical modeling, linguistics, and testing theory. The technology uses a speech processing system that is specifically designed to analyze speech from native and non-native speakers of English. In addition to recognizing words, the system also locates and evaluates relevant segments, syllables, and phrases in speech. The Versant system then uses statistical modeling techniques to assess the spoken performance.

Independent studies have shown that Versant tests are more objective, and more reliable than today's best 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.
