What is it called when someone says "like" or "alright"

I was talking with my friend and neither of us could think of the word for when someone says something similar to "And, like, we were totally, like, going to do this one thing."

From _Wikipedia: Filler (linguistics)

In linguistics, a filler is a sound or word that is spoken in conversation by one participant to signal to others that he/she has paused to think but has not yet finished speaking. [...] Different languages have different characteristic filler sounds; in English, the most common filler sounds are uh, er, and um. Among youths, the fillers "like", "y'know", "I mean", "so", "actually", "basically", and "right" are among the more prevalent.
