Ear devices have been on the market for many years and are available in many price ranges. These electronic aids either delay or alter the sound of one's voice, creating an echo, or play some sort of noise, both of which are known to reduce stuttering. However, it is also known that the effects may wear off over time. There is not enough data on the long-term effectiveness of the devices at this time - something the Stuttering Foundation is working to address.

Below is a list of electronic aids, software, and apps. Some people who stutter have found them to be helpful, particularly in limited situations, such as using the telephone or giving a speech.
