Automaatika referaat (eng)
recognition based automatic pronunciation scoring system for Dutch by using features
such as log likelihood Hidden Markov Model scores, various duration scores, and
information on pauses, word stress, syllable structure, and intonation. They also found
good agreement (correlations above 0.70) between machine scores and human ratings of
pronunciation. Stanford Research Institute (SRI) International, similarly, has been developing
an automatic pronunciation scoring system, EduSpeakTM, which measures phone accuracy,
speech rate, and duration distributions for non-native speakers who read English texts
(Franco et al., 2000). Unlike in Ordinate's test, the texts being read need not be known to
the system for prior training.
At Educational Testing Service (ETS), research in automated speech scoring has
been conducted since 2002. In 2006 a first speech scoring system, SpeechRaterSM, was
successfully deployed to score the speaking section of TOEFL
