EchX – Stuttering Aid (DAF) is a powerful yet simple speech therapy tool designed to help people who stutter or experience disfluency improve their speech fluency and confidence.
Using the scientifically proven Delayed Auditory Feedback (DAF) technique, EchX lets you hear your own voice with a slight delay, helping your brain synchronize speech patterns and reduce stuttering tension.

Whether you are a speech therapy professional, a student, or someone working independently on fluency, EchX provides you with an effective and customizable environment to practice clear, confident speech — anytime, anywhere.

🌟 What is DAF (Delayed Auditory Feedback)?

DAF is a method that plays your own speech back to you with a slight time delay.
When the delay is just right, your brain receives the auditory feedback out of sync with your actual speech, which naturally encourages you to slow down and speak more smoothly.

This effect has been studied for decades and is widely used in speech therapy for stuttering, fluency shaping programs, and public speaking training.

With EchX, you can fine-tune the delay value to match your personal needs and find the sweet spot that works best for your voice and speech rhythm.

🗣️ How EchX Helps

People who stutter often find that when they hear their voice slightly delayed, their brain automatically adjusts timing and rhythm, leading to slower, more fluent, and controlled speech.
Using EchX regularly can help:

Reduce stuttering frequency and intensity

Improve breathing and speech pacing

Build awareness of speech patterns

Increase confidence in speaking situations

Even if you are not working directly with a therapist, EchX can be a valuable self-training tool to complement exercises such as reading aloud, repeating phrases, or practicing public speaking.

⚙️ Tips for Best Results

Always use wired headphones for minimal delay.

Experiment with different delay settings (start around 100ms and adjust).

Speak slowly and focus on clear pronunciation.

Practice daily for several minutes to notice gradual improvement.

Combine EchX with relaxation and breathing exercises for best results.
