No. Acceleration is the change in velocity(speed) over a period time.
=====================================
Another contributor bristled:
Sorry. Velocity and speed are not two different words for the same thing.
Velocity means speed and direction, and acceleration means any change in velocity.
If the speed is constant but the direction is changing ... like turning a corner or driving
on a circular track ... then velocity is changing, and there is acceleration.

0. "Constant speed" means it is not accelerating.
if the velocity is constant, the acceleration is zero. The acceleration is the rate at which the velocity changes, so if it stays the same, the car isn't accelerating.
It depends on which direction you are resolving the acceleration from. If you use the original direction of the car as it turns it is decelerating as the speed it is moving in that direction is decreasing. If you resolve from the direction which the car will be going towards then it is accelerating as its speed in that direction is increasing.
The acceleration of an object that travels in a constant straight line velocity is zero.
