Record a series of messages to this dedicated speech generating device and then activate the 2.5-in/6.4-cm switch top to play each message back one at a time.
VOCAs are electronic devices we use to give the children a “voice”.
The simplest devices are those on which the therapist and classroom staff record a simple message.
The child presses on the device to hear the message and becomes an active partner in the conversation, circle time activity, stories & so on. We use two VOCAs together to enable the child to make choices.
More sophisticated VOCAs allow us to record multiple messages so that the child can hold a simple conversation.
