Learn Latvian Letters & pronunciation (Open source)

For long time I wanted to make something educational like this.

In my opinion Latvian is one of easiest languages to learn to speak and that means easier to read, because in Latvian there's mostly only one sound for each letter.

So here I pronounce the letters as they are used in the spoken language. Any feedback appreciated.
