Phonological evidence supports the frequency-based model proposed in the article by Nick Ellis. Phonological reduction occurs earlier and to a greater extent in high-frequency words and phrases than in low-frequency ones. A model that accounts for this effect needs both an exemplar representation to show phonetic variation and the ability to represent multiword combinations. The maintenance of alternations conditioned by word boundaries, such as French liaison, also provides evidence that multiword sequences are stored and can accrue representational strength. The reorganization of phonetic exemplars in favor of the more frequent types provides evidence for some abstraction in categories beyond the simple registration of tokens of experience.
