AccentHelp coach Jim Johnson goes further into how the soft palate (velum) works, and tricks and tips on how to lift it:
The soft palate is especially liable to drop if your using a low amount of energy, so just boosting your oomph can make a big difference in reducing nasality. Putting your weight forward onto your toes, for example, will often make the velum lift just because of the energy boost.
Jim also covers other tricks, such as the Lion’s Roar Smile/Half-Yawn and Crazy Eyes. You may lose friends, but your velum will be up!
