Which result most directly reflects meaningful change in therapy goals for AOS?

• A. Increased speaking rate without loss of intelligibility.
• B. More accurate articulation of isolated phonemes.
• C. Improved intelligibility and consistent production of longer, more complex utterances with accurate sequencing.
• D. Greater consistency in syllable structure across utterances.

Answer: (C)

In AOS therapy, meaningful progress is best shown when a person becomes more understandable in connected speech, with the ability to plan and produce longer, more complex utterances accurately. The result that combines improving intelligibility with consistent production of longer utterances and accurate sequencing directly reflects the motor planning and sequencing skills targeted in therapy, indicating real functional gains in everyday communication.

The other possibilities are more limited in scope: increasing speaking rate without losing intelligibility can be helpful, but speed alone without clarity doesn’t demonstrate meaningful communicative improvement. Articulating isolated phonemes accurately shows fine motor control in single sounds but doesn’t reveal how those sounds flow together in longer speech. Greater consistency in syllable structure across utterances suggests pattern control but doesn’t guarantee improved overall intelligibility or the ability to produce complex, sequenced speech.
