This is the original vocalist on The Little Mermaid. She has a pretty good example of some nice high vowels. All of the vowels that are typically deeper, such as ah, eh, and oh, are pretty well executed. I also like that she acts with her voice. Such a speaking a line or word, having fun with her questions, etc., all help bring the song to life.
Her voice does sound a bit nasally and that is, I believe, a quality that is just a part of her voice. However, because of that quality, other vowels such as ih and ae are more forward without the depth to them. But I do like her example of making even the deeper vowels sit a little higher so they have more color.
