SPEECHROUTE mobile app supports people who stutter in increasing speech fluency using altered auditory feedback
Download on App StoreAccording to studies, this method can increase your speech fluency by 60-90%. To maximize the effectiveness, use the app properly and incorporate speech techniques recommended by a speech-language pathologist.
When you first open the app, everything will be set up for immediate use. Simply connect your headphones to your mobile phone, turn ON the app, and start speaking. You will notice a changed perception of your speech which can lead to an increase of speech fluency.
We recommend using both delay modules (Delay 1 and Delay 2) with a fixed 100 ms interval. A common setup is 75 ms for Delay 1 and 175 ms for Delay 2, though you can adjust the values to suit your preference. In most cases, a Delay 1 range of 50–80 ms works well.
For adults who stutter, use LPF at 300 Hz and HPF at 2400 Hz. For children, use LPF at 600 Hz and HPF at 4800 Hz. You can also experiment to find what works best for you.
1. Do not use the app constantly throughout the day, but only in specific speaking situations. If you continuously use this method, your brain may become accustomed to the altered perception of speech, and the positive effect on speech fluency may diminish.
2. For best results, make sure to wear both headphones in your ears, not just one. Additionally, using headphones with rubber caps to block out external sounds will help your brain have an undisturbed altered perception of speech and increase the effectiveness of this method.
3. Regularly practice your speech using speech techniques recommended by a speech-language pathologist. The combination of speech therapy and the SPEECHROUTE mobile app will result in high level of speech fluency even in the most challenging speaking situations.
The operation of the SPEECHROUTE mobile application is based on the Verbotonal method. According to this method, separating low-frequency speech signals from the high-frequency ones results in a clearer and more efficient perception of speech rhythm, tempo, and intonation. On the other hand, high-frequency speech signals, which the brain receives with a slightly longer delay compared to low-frequency signals, serve for uninterrupted speech intelligibility.
Through this science-backed altered perception of speech, the inconsistent and unreliable speech perception encountered by individuals who stutter is eliminated. This method leads to a recalibration of the neural processes accountable for speech production, resulting in a substantial enhancement in speech fluency.
