A single case study is presented of a patient, LT, with a reproduction conduction aphasic pattern of performance on word reproduction tasks; thus he made substitutions, insertions, deletions, and transpositions in reading, writing, and repetition of words and nonwords, as well as in sentence production, and in spoken and written picture and action naming. Further analyses revealed that there was no effect of semantic or syntactic structure on performance, and that reading was slightly better… 
Phonological, lexical, and semantic errors produced by impairment at the output buffer in a Spanish aphasic patient
TLDR
The deficits observed in this patient, and the differences encountered between her performance and that of others described in the literature, can be explained by considering POB damage to be gradual in nature.
The Selective Impairment of the Phonological Output Buffer: Evidence From a Chinese Patient
TLDR
It is argued that this dissociation is evidence that the phonological output buffer is not involved in writing Chinese words, and that the buffer has a structure that makes the onset more prone to impairment.
Imageability effects, phonological errors, and the relationship between auditory repetition and picture naming: Implications for models of auditory repetition
TLDR
The present paper investigates the performance of a new patient (MF) who also makes a large number of phonological errors when repeating words of low imageability, and argues that the pattern of performance that MF demonstrates can be readily accommodated in terms of the dual-route account of impaired auditory repetition.
Breaking the mirror: Asymmetrical disconnection between the phonological input and output codes
TLDR
The results suggest that the phonological codes in perception and in production are separate but connected by two conversion mechanisms and that these two mechanisms can be disrupted independently.
Segmental and metrical encoding in aphasia: Two case reports
Background: Phonological impairment in aphasic patients most often affects the segmental structure of words, while metrical structure, i.e., syllable number and stress position, is usually preserved.
Phonological short-term memory in conduction aphasia
Background: Within cognitive neuropsychological models conduction aphasia has been conceptualised as a phonological buffer deficit. It may affect the output buffer, the input buffer, or both. The
Case Study Impairment to phonological processes in a Cantonese‐speaking brain‐damaged patient
  • S. Law
  • Linguistics, Psychology
  • 2004
Background: Previous studies have shown that brain‐damaged patients with selective deficits to phonological processes produced frequent phonological errors and similar error patterns in all spoken
Jargon dyslexia in an individual with semantic dementia: Further evidence for task-specificity in phonological output
TLDR
It is demonstrated that the patient with semantic dementia has a task-specific phonological deficit and it is argued that reading and propositional speech rely upon dissociable phonological output systems.

TLDR
The spelling performance of two patients with a selective deficit in writing vowels is described, which supports the hypothesis that the consonant/vowel status of graphemes is differentially specified in the spelling process and may be selectively affected after brain damage.
