Can all schizophrenic speech be discriminated from normal speech?

H A Allen

    The British Journal of Clinical Psychology
    |September 1, 1985
    PubMed
    Summary

    Schizophrenic speech, even in individuals without diagnosed speech disorders, can be distinguished from normal speech. This indicates unique speech patterns in all schizophrenic patients, though the specific differences remain unclear.

    Area of Science:

    • Psychiatry
    • Linguistics
    • Clinical Psychology

    Background:

    • Schizophrenia is a complex mental disorder.
    • Speech abnormalities are sometimes observed in schizophrenia.
    • The extent to which speech differs in schizophrenic individuals, including those without overt speech disorders, is not fully understood.

    Purpose of the Study:

    • To determine if the speech of individuals with schizophrenia (both with and without co-occurring speech disorders) is distinguishable from the speech of individuals without schizophrenia.
    • To investigate potential subtle speech differences in schizophrenia.

    Main Methods:

    • A qualitative analysis utilizing clinical expertise to discern differences in speech patterns.
    • Focus on the ability to discriminate schizophrenic speech from normal speech, rather than specifying the exact nature of the differences.

    Main Results:

    • Clinicians could accurately discriminate the speech of individuals with schizophrenia from that of normal individuals.
    • This discriminability was observed even in schizophrenic patients who did not present with primary speech disorders.

    Conclusions:

    • The speech of all individuals with schizophrenia differs from that of individuals without the disorder.
    • These speech differences exist but require further research to be specified and understood.
