The flash also has the ability to talk very fast. This ability is known as speed-talk. He can use this ability to communicate with other speedsters very fast. 

The flash can also vibrate his vocal cords. By doing so, he can change his voice; so others cannot identify his voice. 

The flash can also make vortexes and sometimes lighnings using his super speed running ability.

Another special ability he posses is the ability to make speed avatars or duplicates. He can send these avatars to different timelines to complete important tasks or missions.
