This review evaluates seven acoustic speech analysis systems, detailing their components, capabilities, and performance. Recommendations are provided for enhancing future speech analysis software development.

Area of Science:

  • Acoustic Speech Analysis
  • Speech Science Technology

Background:

  • Multiple acoustic speech analysis systems are commercially available, serving diverse research and clinical needs.
  • Evaluating system performance is crucial for selecting appropriate tools for speech research and diagnostics.

Purpose of the Study:

  • To comprehensively review and compare the performance characteristics of seven established acoustic speech analysis systems.
  • To tabulate basic capabilities of three recently introduced systems.
  • To offer recommendations for the future development of speech analysis systems.

Main Methods:

  • Systematic review of system components, basic capabilities (signal acquisition, waveform operations, analysis, data formats, journaling), documentation, and user interface.
  • Evaluation of speed and precision for spectral and fundamental frequency analysis.
