Which treatment approach involves contrasting two phonologically dissimilar sounds?

The maximal-oppositions approach focuses on contrasting phonologically dissimilar sounds that differ by features such as voicing, place of articulation, and manner of articulation. This approach is designed to address phonological processes in children with speech sound disorders by targeting pairs of sounds that are maximally distinct to facilitate generalization to other sounds that are affected by similar phonological rules. By utilizing sounds that are as different as possible, this method can encourage the development of contrastive phonemic awareness and improve overall speech clarity.

In contrast, the multiple-oppositions approach works with several sounds that are affected by the same phonological process, while the minimal-pairs approach also targets sounds that are similar, differing by just one feature. The metaphonological approach emphasizes awareness and understanding of the sound structure of language, rather than directly contrasting phonemes.
