Description: This approach is specifically targeted toward children with severe phonological impairments who demonstrate an extensive phoneme collapse.

Phoneme Collapse: when a child uses one single consonant sound to substitute many (multiple) other sounds. The greater the phoneme collapse, the greater the impact on overall intelligibility.

For example: If a child says /t/ for /k/, /s/, /ʃ/, and /tʃ/ then two, coo, sue, shoe, and chew, would all become /tu/

This approach consists of 4 phases. Before beginning treatment you will want to identify the child’s specific phoneme collapses and generate a list of target words.

Phase 1: Familiarization

Phase 2: Production of contrasts / interactiveplay

Phase 3: Constrasts within communicative context

Phase 4: Conversational recasts
