Hello, I've trained two vowels today, which are strong [a:] as in father and strong [o:] as in warm. Please, native American English speakers listen to two recordings below and give me feedback on my pronunciation of these vowels. It's crucial to me, because if there is no feedback I won't know whether I need to move on to another lessons or to work more on the current vowels. As I did with the previous vowels I pronounced these new two vowels on their own first then as a part of some words.
