Abstract
In a method for quantitatively evaluating a pronunciation of a speaker, an acoustic signal is received from the speaker, which represents an utterance spoken in a language by the speaker. The acoustic signal is segmented into segments at the phone, word or phrase level. The acoustic signal segments are each transcribed by a high fidelity transcriber into high fidelity transcription segments that each comprises a sequence of phones that represents how the native or normative speakers of the language would likely perceive a playback of the acoustic signal segment. Each of the high fidelity transcription segments are compared to a baseline to generate one or more pronunciation scores that evaluate the pronunciation of the speaker. The baseline may be generated by transcribing the acoustic signal into an adapted transcription that comprises a sequence of phones that represents how native or normative speakers of the language would likely speak the utterance.
