Percent Number Tones Correct (PNTC)
The Percent Number Tones Correct (PNTC) analysis compares the numbered tones on aligned IPA Target and IPA Actual syllables and reports the percentage of target tones produced correctly. To review how tone numbers are specified in Phon please see ../../transcription/ipa_transcription.html#phone__tone_number.
The report produced by the analysis includes a Summary section with overall PNTC results across all participants together with breakdowns by tonal pattern and IPA pattern, per-participant sections, and a listing of all results. See #pntc__report-outline for details.
Data Preparation
Session data is queried by word for each IPA Target and IPA Actual tuple. Proper syllabification and phone alignment is required for accurate results. All participants should have unique names/identification numbers and a speaker should be assigned to all records.
