Speech Devices

What do these things do? Well it seems they delay us hearing the sound of our voices and so interrupt the feedback we normally expect. This upsets the applecart and we speak differently. I say we speak differently because although they disrupt the PWS and so make it harder to keep up the self monitoring that goes with stammering, DAF machines also lead those who don’t stammer to speak stammeringly.

I know someone who took part in an undergraduate experiment with a DAF machine. He saw how others stammered and decided to ignore the feedback and keep talking. He didn’t stammer. The lecturer was upset.

We attend to novelty because the world becomes more interesting or less safe.

By attending to something other than what we normally attend to we behave differently.

If we don't want what we have always got then we have to behave differently.
