Not exactly. Although the time it takes for the ball to travel to the end of the inclined plane depends on the plane's pitch, the ball's speed is always the same at the end of the plane no matter what its pitch.
One of the problems that Galileo faced when conducting experiments dealing with gravity was that the objects in a free fall were moving too quickly to be accurately measured by existing timing methods (which were as crude as using a person's heartbeat). He showed with an experiment similar to this one and logic that an inclined plane could be used to slow the effects of gravity while still maintaining the rate of acceleration, and then he used an inclined plane to determine the actual rate of acceleration...
