are varieties of speech different languages or different dialects?

There is no single answer.  Four factors may be important:

1. Linguistic - mutual intelligibility

2. Cultural - values and opinions of ordinary speakers

    Standard form - is there a norm followed by literate users?

3. Political - what the people in charge dictate

    If two speech forms are mutually intelligible, share one standard, are considered one language by the speakers, then they are dialects--unless politics intervenes. 

    But if two speech forms are not mutually intelligible, they are different languages--unless there is some overriding political or cultural reason to consider them one language

    JOKE:  "A language is a dialect with an army and a navy."
