Which component includes activities to improve articulation and intelligibility?

The correct answer focuses on speech sound production training, which directly addresses the skills related to articulation and intelligibility. This component involves specific activities and techniques designed to help individuals produce sounds correctly and clearly, enabling better communication.

Speech sound production training may include exercises that target individual phonemes, patterns of speech sound errors, and practice with models and cues to facilitate correct pronunciation. By concentrating on these areas, this training not only enhances an individual's articulation but also improves their overall intelligibility—the clarity with which speech can be understood by others.

In contrast, voice therapy primarily addresses issues related to pitch, volume, and quality of voice rather than improving specific speech sounds. Auditory training focuses on developing listening skills and the ability to process sounds, which does not directly target articulation. Literacy pertains to reading and writing skills rather than speech production. Therefore, speech sound production training is the most relevant component for improving articulation and intelligibility.
