Analysis: PPC

The PPC analysis will calculate the percent phones/consonants/vowels correct (PPC/PCC/PVC) in the sampled data.

Report Outline

The report will be composed of two types of tables:

  • PPC Summary
  • PPC Listing

An example table of contents is displayed below. Bold level elements are section headers while italic items are one of the tables listed above. Other headings are standard Phon report elements or text blocks.

  • PPC/PCC/PVC
    • Parameters
    • Summary
      • PPC Summary (All Participants)
      • PPC Summary (Participant 1)
      • ...
    • Breakdown
      • PPC Listing (Participant 1)
      • ...

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.

Parameters

PPC Summary

The PPC Summary tables display # Target, # Correct, # Substituted, # Deleted, # Epenthesis, PPC/PCC/PVC (Percent Phone/Consonant/Vowel Correct) for the sampled data. When displaying the summary for "All Participants" each row is the summary for a single speaker with a final row displaying totals for all speakers. When displaying the summary for a participant, each row shows the totals for the participant in the indicated session. The caption of the table will be “All Participants” or “Participant Name”.

Example (All Participants)

Speaker Role # Target # Correct # Substituted # Deleted # Epenthesized PCC
CHI Target Child 1202 700 265 237 64 55.29
Kiddo Target Child 249 168 60 21 16 63.4
Total 1451 868 325 258 80 56.69

Example (Participant)

Session Role Age # Target # Correct # Substituted # Deleted # Epenthesized PCC
CHI.Session1 Target Child 01;10.11 321 165 68 88 17 48.82
CHI.Session2 Target Child 01;11.22 445 254 106 85 30 53.47
CHI.Session3 Target Child 02;02.15 436 281 91 64 17 62.03

PPC Listing

The PPC Listing table displays # Target, # Correct, # Substituted, # Deleted, # Epenthesis, PCC/PVC (Percent Consonant/Vowel Correct) for each word sampled. The table will have the caption “Participant Name”.
