Design outcomes

Primary

Measure	Time frame
Phoneme recognition test: It is a test specifically designed to evaluate phonological level auditory processing ability in cochlear implant users. Timepoint: The score is a percentage obtained through testing and observation. The test will be conducted eight weeks before the intervention phase, during the intervention phase once time every week, once a week after the intervention phase for eight-week. Method of measurement: Phoneme recognition score based on PRT, Quantitative score based on PST, Qualitative score based on PST, Qualifiers representing buffalo model subcategories based on PST, Speech discrimination score based on WRS, Patterns, and frequency of phoneme errors including omission, substitution, added and total based on PEA.	—

Secondary

Measure	Time frame
Phoneme synthesis Test: Presenting a phoneme to a phoneme is a meaningful (or nonsensical) word in which the listener is obliged to stick these phonemes together and to express the word forming it. Timepoint: The raw data points are obtained through testing and observation. This test will be performed before the intervention once a week for eight weeks, during the intervention once a week for eight weeks and after the intervention once a week for eight weeks. Method of measurement: The 54 words in the one-to-four syllable that are referred to as full-color images form the test items. The general requirements for word assignment are frequency testing, high imaging capability and specific item allocation conditions are consistent with the test objectives. Among the vocabulary assigned to this test are 31 single syllables, 18 binary syllables, three syllables, and one quadratic syllable, and 29 end-of-sentence words.	—
