When to use the weak form /ə/ and when to use the weak form /eɪ/ of the article "a"? I figure if I would emphasize anything I wouldn't emphasize an article like "a", but rather, the noun (phrase) following it. But still I've heard people occasionally use /eɪ/. What's the point of that?

    And also: "Have you seen my dog?" "I saw a dog." – Hugh Jun 13 '15 at 13:19
