About Speech Jammer°
Speech Jammer will record your voice and replay it back to you at an adjustable delay. This is known as Delayed Auditory Feedback (DAF) and results in difficulty speaking. You just put on your headphones, turn up the volume and read the sentences. The more you spontaneously and continuously talk with the Speech Jammer, the harder talking becomes. Speech Jammer Features ● Adjustable delay to impair speech ● Tongue twisters to make it even more difficult ● Ability to record Speech Jammer sessions ● Share recordings with your friends ● Simple and easy-to-use layout Speech Jammer works best with noise cancelling headphones and headphones with the microphone built-in.
