Speed is a scalar quantity. Just one number. For example miles per hour or meters per second.
Velocity is a vector quantity. Two numbers(speed and direction).
Since speed is one part of velocity, if speed changes velocity changes.
So you can't have an object with varying speed and constant velocity.

NOT POSSIBLE.
Speed has magnitude only while Velocity has magnitude and direction. If speed is varying then velocity must vary as it's magnitude is varying

speed is the magnitude of the velocity vectory..thus.. constant vector=constant speed.
