Safety
Vocal safety
Practical safety boundaries for educational voice training with Basaltone.
Stop signals
Stop with pain, burning, sudden voice loss, breathing or swallowing difficulty, or effort that keeps increasing. Do not train through symptoms to reach a number.
Recovery
Return to comfortable ordinary speech and allow recovery. Reduce range, volume or duration after fatigue.
Professional care
Persistent hoarseness or concerning symptoms require an appropriate qualified professional. Basaltone cannot inspect the vocal folds or diagnose a cause.
