This paper discusses mechanisms of recurring utterances in a female patient with slowly progressive aphasia. The patient, TO, produced a meaningless recurring utterance [ko-no-shi:-no] in her spontaneous speech, but her ability to rewrite words written in kanji(Japanese ideograms) to kana(Japanese phonograms representing syllables or moras) sequences was relatively preserved. It was speculated that the production of spontaneous speech and writing kana sequences from kanji words share the phoneme level from speech output lexicon based on the cognitive model. Thus, The relatively preserved ability to rewrite kanji words to kana strongly suggests that the recurring utterance in this case was produced below the phoneme level as described by Blanken.
