Stilted speech

In psychiatry, stilted speech or pedantic speech[1] is communication characterized by situationally-inappropriate formality.[2] This formality can be expressed both through abnormal prosody[3] as well as speech content that is "inappropriately pompous, legalistic, philosophical, or quaint".[4] Often, such speech can act as evidence for autism spectrum disorder (ASD)[3] or a thought disorder,[5] a common symptom in schizophrenia[6] or schizotypal personality disorder.

To diagnose stilted speech, researchers have previously looked for the following characteristics:[7]

  • speech conveying more information than necessary
  • vocabulary and grammar expected from formal writing rather than conversational speech
  • unneeded repetition or corrections

While literal and long-winded word content is often the most identifiable feature of stilted speech, such speech often displays irregular prosody, especially in resonance.[7] Often, the loudness, pitch, rate, and nasality of pedantic speech vary from normal speech, resulting in the perception of pedantic or stilted speaking. For example, overly loud or high-pitched speech can come across to listeners as overly forceful while slow or nasal speech creates an impression of condescension.[8]

These attributions, which are commonly found in patients with ASD,[8] partially account for why stilted speech has been considered a diagnostic criterion for the disorder.[7] Stilted speech, along with atypical intonation, semantic drift, terseness, and perseveration, are all qualities known to be commonly impaired during conversation with adolescents on the autistic spectrum.[9] Often, stilted speech found in children with ASD will also be especially stereotypic or rehearsed.[9]

Patients with schizophrenia are also known to experience stilted speech. This symptom is attributed to both an inability to access more commonly used words and a difficulty understanding pragmatics—the relationship between language and context.[10] However, stilted speech appears as a less common symptom compared to a certain number of other symptoms of the psychosis (Adler et al 1999).[11] This element of cognitive disorder is also exhibited as a symptom in the narcissistic personality disorder (Akhtar & Thomson 1982).[12] There is disagreement on the definition of psychophenomonology within the discipline of psychiatry, e.g. published sources provide definitions that are "various and sometimes conflicting (Rule 2005)" (Andreasen 1979).[13][14]
