Summary
Amplifying a speaker's own voice (sidetone) reliably causes them to speak quieter. This effect remained stable across different conditions and over multiple days in two separate experiments.
Area of Science:
- Auditory perception
- Speech production
- Human-computer interaction
Background:
- The sidetone amplification effect describes how increased auditory feedback of one's voice leads to reduced vocal output.
- Understanding the reliability of this effect is crucial for applications involving voice control and communication.
Purpose of the Study:
- To investigate the reliability and stability of the sidetone amplification effect.
- To assess how varying experimental conditions influence this vocal response.
Main Methods:
- Two experiments were conducted to examine the sidetone amplification effect.
- Experiment 1 involved gradual modulation of auditory feedback during a single session.
- Experiment 2 assessed the effect over five consecutive days of testing.
Main Results:
- The sidetone amplification effect demonstrated high stability in both experimental setups.
- The vocal response remained consistent despite variations in eliciting conditions.
- Reliable reduction in voice amplitude was observed with amplified auditory feedback.
Conclusions:
- The sidetone amplification effect is a robust phenomenon.
- This effect is reliable under different experimental conditions and over extended periods.
- Findings support the consistent influence of auditory feedback on vocal regulation.
