I am working on an app to provide Auditory Feedback to users to help speech fluency, comprehension, and pronunciation. Essentially trying to create a digital version of this product: Toobaloo (I have no affiliation with that product).
About Auditory Feedback they state:
What Is Auditory Feedback?
Auditory Feedback is the task of hearing the sound of one's own voice while speaking, which enables adjustments in pronunciation, clarity and the rhythm of speech. Auditory Feedback is used in speech, language, auditory processing and reading therapy programs.
However, by the nature of digital mediums and the apps implementation it is unlikely I will get the feedback down to real-time, according to Wikipedia a delay of even 175ms can result in mental stress as seen by Delayed Auditory Feedback :
Delayed Auditory Feedback (DAF)
is a device that enables a user of the device to speak into a microphone and then hear his or her voice in headphones a fraction of a second later. Some DAF devices are hardware; DAF computer software is also available. DAF usage (with a 175 millisecond delay) has been shown to induce mental stress.
However, I noticed both of these statements dicatate that the feedback is provided in the users own voice.
I was wondering if there was any research available in changing the voice of the feedback to help reduce stress and confusion from feedback delay?
EDIT: Conversely, if changing the voice decreased the stress and confusion from Delayed Auditory Feedback would it also decrease the benefits of Auditory Feedback on speech therapy?
