When I turn on my car there's a speaking noise it sounds like a pulley since the noise is coming from the front of the car, i have yet to look at it, but does anyone have any ideas? It happens even if the engine is cold, the belt has been changed recently too, Let me know what you think! Thanks

It helps to identify the year, engine. "The belt has been changed" isn't specific either, there's more than one. You could start by spraying a little WD-40 on the inside of the ribbed accessory belt while idling, and if the noise goes away, then change that one. Do the same to any other accessible belts to see if they get quieter after spraying. If there's still noise, I'd next take the ribbed serpentine off and spin everything driven by it, listening for noise and feeling for movement. Start the car with the belt off, and listen for the noise. If it's still there, and is coming from behind the timing belt cover, better not run the car any more until the TB and pulleys are inspected.

Does the noise go away after a minute or so? If so, it'll be your secondary air injector pump.
