I have an avi of a scene where there are truck and people talking. I cannot hear the talking over the truck noise. Can I remove the truck noise and boost the talking . It was filmed on this camera in case that is important

Probably not. You can try to load the file into audacity, use the noise reduction function and maybe fiddle with equalization. But from your description and the fact that it's a built-in camera mic it's unlikely you will get good results.
The difference between voice and background is largely perceptual -- it's in our minds. As far as the microphone is concerned it's all one big complex sound.
That's why the pros work so hard to get their microphones close to the actors.
Can you remove syrup after drizzling on a pancake? Same problem. There's no way to delineate the two once they meld. Voice and noise share too many frequencies.
We don't actually "hear" sound, we "feel" it. Each frequency resonates as a tone. When frequencies overlap, the tone changes. Our brains interpret the tones based on our life experience. A Zulu tribe would not hear a Rock Band as such.
