"It is good … to remember this sound matrix."

[Odessa Dawn]

​

"So, your question is fantastic. And this, I call this the cancellation matrix. Cancellation matrix. The (S) (N) (L), the (d) (t )(th). This covers most cancelled sounds in American spoken English. And you can remember it. The strong sounds; Shane, that is me Shane, Shane never lies. Shane never lies. The weak sounds, Don’t trust that. Don’t trust that. Now, you can trust it. Shane never lies. Don’t trust that. Ah! It is confusing. It is good … to remember this sound matrix. The cancellation matrix"
