Two sounds close enough to trade places: the “r” of red and the “l” of leg. Swap one for the other and a different word comes out — this page is how to keep them apart, in both directions.
Keep your tongue tip away from the ridge; curl or bunch the tongue back so nothing touches the roof of the mouth.
“The tongue touched the roof! I felt it from here! For this sound the tongue floats — touches NOTHING. Like a hovering gnocchi!”Nunzio, when he hears it
Touch your tongue tip firmly to the ridge behind your top teeth and let sound flow around the sides.
“Now the tongue MUST touch! Press the tip behind the top teeth — a firm little kiss — and sing around the sides!”Nunzio, when he hears it
You cannot hear your own swap. That is the whole problem.
Nunzio records you reading a sentence, scores every sound in it on your phone — nothing is uploaded — and tells you which of these two actually came out. Nunzio — Accent Coach is coming to the App Store and Google Play.
