A METHOD, SYSTEM AND SOFTWARE FOR TEACHING PRONUNCIATION

摘要

The present invention relates to a method for teaching pronunciation. More particularly, but not exclusively, the present invention relates to a method for teaching pronunciation using formant trajectories and for teaching pronunciation by splitting speech into phonemes. (A) A speech signal is received from a user; (B) word(s) is/are detected within the signal; (C) voice/unvoiced segments are detected within the word(s); (D) formants of the voiced segments are calculated; (E) vowel phonemes are detected with the voiced segments; the vowel phonemes may be detected using a weighted sum of a Fourier transform measure of frequency energy and a measure based on the formants; and (F) a formant trajectory may be calculated for the vowel phonemes using the detected formants.
