Summary
Speech recognition software can cause voice problems like hoarseness. Individuals with cumulative trauma disorder may be more susceptible to these vocal issues when using discrete speech dictation systems.
Area of Science:
- Speech-language pathology
- Occupational health
- Human-computer interaction
Background:
- Commercial speech recognition (SR) systems are increasingly used as alternative computer input devices, especially by individuals with physical disabilities.
- Discrete SR systems necessitate distinct pauses between words, altering natural speech patterns.
- Anecdotal reports suggest users experience voice problems, including hoarseness and sore throat.
Purpose of the Study:
- To investigate the potential voice problems associated with using discrete speech recognition systems.
- To identify user groups potentially more susceptible to these voice issues.
Main Methods:
- Preliminary study involving survey dissemination.
- Clinical data collection and analysis.
Main Results:
- Individuals with cumulative trauma disorder appear more susceptible to voice problems.
- Hypothesized tendency to maintain constant pitch, volume, and inflection, potentially leading to vocal muscle fatigue and injury.
Conclusions:
- Discrete SR systems may pose risks to vocal health.
- Further research is needed to confirm the suggested effects.
- Users should practice vocal hygiene and consider alternative input methods.
