For the purpose of developing Computer Assisted Pronunciation Training (CAPT) technology with more informative feedbacks, we propose to use a set of narrow-phonetic labels to annotate Chinese L2 speech database of Japanese learners. The labels include basic units of “Initials”, “Finals” for Chinese phonemes and diacritics for erroneous articulation tendencies. Pilot investigations were made on the annotating consistencies of two sets of phonetic transcriptions in 17 speakers’ data. The results indicate the consistencies are moderately good, suggesting that the annotating procedure be practical, and there are also rooms for further improvement.
