Hearing

Question 1

Outer Ear

Answer 1

captures pressure waves (disturbances in air) created by speech

Question 2

Middle Ear

Answer 2

converts these waves to mechanical vibrations

Question 3

Inner Ear

Answer 3

converts the vibrations to vibrations in fluid which are then transformed into electrochemical information sent to the brain via the Auditory Nerve (VIII)

Question 4

Delayed Auditory Feedback (DAF)

Answer 4

Delays what the consumer hears by a few milliseconds (ms)

Think of the DAF as an echo

Question 5

Frequency Altered Feedback (FAF)

Answer 5

Alters the pitch perception of the consumer’s voice

This can be raised or lowered depending on the consumer’s preference

Question 6

How does SpeechEasy work?

Answer 6

The theory is that stuttering can be inhibited by the use of choral speech.

Choral speech is nothing more than people saying the same thing at the same time.

SpeechEasy uses Delayed Auditory Feedback (DAF) and Frequency Altered Feedback (FAF) to emulate choral speech.
