Summary

Speech analysis using RELATEX/RELATAN revealed tuberculosis patients express more evaluations and attitudes than lung cancer patients or healthy individuals. This computer-oriented method shows promise for psycholinguistic research.

Area of Science:

  • Psycholinguistics
  • Computational Linguistics
  • Medical Speech Analysis

Background:

  • Altered speech patterns can indicate underlying medical conditions.
  • Computerized analysis offers objective methods for studying linguistic features.
  • Distinguishing speech characteristics in lung cancer and tuberculosis patients is clinically relevant.

Purpose of the Study:

  • To investigate speech patterns in patients with lung cancer and tuberculosis.
  • To compare these patterns with those of healthy controls.
  • To evaluate the utility of the RELATEX/RELATAN system in psycholinguistic research.

Main Methods:

  • Analysis of speech patterns from 28 patients (17 lung cancer, 11 tuberculosis) and healthy controls.
  • Utilized a computerized speech analysis method: RELATEX/RELATAN.

  • Compared linguistic features between patient groups and controls.

    • Main Results:

    • Tuberculosis patients' speech exhibited more frequent expressions of evaluations and attitudes.
    • Lung cancer patients' speech patterns differed from healthy controls, though less distinctly than tuberculosis patients.
    • The RELATEX/RELATAN system successfully identified group-specific speech characteristics.

    Conclusions:

    • Speech analysis via RELATEX/RELATAN can differentiate between tuberculosis, lung cancer, and healthy individuals.
    • The computer-oriented method is a valuable tool for psycholinguistic research.
    • Further research is warranted to explore the full potential of this methodology in clinical settings.
