Editing Visible Speech (section)

== Method ==

The idea of the use of a [[Optical spectrometer|spectrograph]] to translate speech into a visual representation (a [[spectrogram]]) was created in the hopes of enabling the deaf to use a telephone.<ref name="K">Kopp, 1967. ''Visible Speech Manual''.</ref> If the sounds could be translated into something readable, then a deaf person at the receiving end could then read out the pattern of speech to determine its meaning without having to hear what was said. The spectrograph readings could also be used to teach pronunciation by having a person speak into the spectrograph and watch a small television-like screen to monitor the precision of their utterances.<ref name="K" />
