Treating Childhood Apraxia of Speech

These procedures target sound sequences (consonant-vowel, consonant-consonant, or vowel-consonant). Sessions begin with Pre-practice to elicit the target sounds, with verbal cueing and shaping strategies. The Practice component then includes chaining that is response-contingent. Participants practice in blocks of 6 consecutive trials beginning at the syllable level. If 5/6 are correct, the participant advances to monosyllabic word practice, then multisyllabic word practice, phrase practice, and sentence practice (with the target syllable embedded within each level of complexity). If fewer than 5/6 trials are correct, a different syllable with the target sound pattern is practiced next. Verbal feedback is faded from 5 of 6 trials at the syllable level to only 3 of 6 trials at the sentence level.

Real-time images of the tongue are made available using ultrasound placed beneath the chin. Participants practice speech movements and can be cued to modify their tongue shape or position to achieve clearer speech. Practice structure is similar to the Speech Motor Chaining procedures, but with the addition of a visual reference.
