Do French people really speak this fast?

[n6zs]

Fast? It's one word of one syllable. There is not a slow way to say it.

[bmcarbaugh]

French people don't actually speak much more quickly than do English speakers. However, it SEEMS like they do because their speech contains a denser concentration of syllables, and they flow from one word to the next (which can be especially confusing to the ear when you're also learning to read french, as we are here).

Next time you talk, think about how fast it would sound to someone trying to learn english. So, yes, they do

[maiklos]

are there alternative ways how to say "yes" in french ?

[Albert_Morris]

There is the colloquial version 'ouais'. This equates to 'yeah' in English.

Not French, but I searched on forvo and it sounds like "weh". Here is a link: http://forvo.com/search/Ouais/
