Which characteristic is not associated with apraxia of speech?

Limited vocabulary is not typically associated with apraxia of speech. Apraxia primarily affects the motor planning and coordination necessary for speech production, which can lead to difficulties with articulating sounds and syllables. Individuals with apraxia may demonstrate inconsistent speech errors, sound distortions, and lengthened transitions while speaking, but their overall understanding of language and vocabulary remains intact.

In contrast, a limited vocabulary is generally associated with language disorders rather than apraxia, indicating a broader difficulty in language acquisition and use, not just in the physical execution of speech. Therefore, a characteristic such as limited vocabulary would not be an indicator of apraxia of speech itself.
