Delayed Auditory Feedback is a free multimedia application designed for Android that allows users to hear their voice with immediate feedback or with a variable delay. This functionality is particularly beneficial for individuals practicing singing, as well as those working on speech improvement, such as stuttering or speech jamming. The app provides a straightforward interface that caters to both casual users and those seeking to enhance their vocal skills.

The application is optimized for use with wired headsets, which offer the lowest latency for real-time feedback. Users can also experiment with recording their voice to track improvements over time. However, it is important to note that using Bluetooth headsets may introduce greater latency, depending on the specific device and headset performance. Overall, Delayed Auditory Feedback serves as a practical tool for voice training and speech enhancement.
