How often and for how long?
Laxvox 3-5 times a day for 2-5 minutes each time. A few short sessions a day are better than one long one.
What do I need to be aware of?
If your cheeks are ‘bubbling’ along and it feels comfortable, you know you are doing it right. The LAX VOX® effects start as soon as the tube is dipped into the water even slightly. There is no need to submerge it particularly much, blow into it very hard, or to laxvox particularly loudly for the exercise to be more effective. On the contrary. Make sure you are comfortable. Experiment by submerging the tube a little more or less, changing the pitch and the volume of air, and find out what best promotes your goals for your voice.
