This was something we made a number of years ago, a simple "Voice Box" which can even be set into a spare wheelchair table, allowing simple communication while out. The local mens shed made the boxes for the school, then the kids painted their boxes. It was a nice fun way to create some low cost assistive Communication .
Parts:
2 x Recordable Voice Module for Greeting Card Music Sound Talk chip musical IG
2 x 60mm Round Illuminated Arcade Video Game Player Push Button Switch LED Light
Both are easily available from E-bay for a few dollars.
Craft Wood Pencil box (recommended size 220mm x 100mm x 70MM(deep) available from many craft stores (optional)
Cut the play button off the wires and either crimp or solder onto the tags on the switch for the button, these can be connected either way around.
The contacts on the button should not be connected to anything as they are for button illumination which is not used as it requires too much power(Pic1)
Fit the switch into the switch holder using the locating tabs, locate the one on the long tab first then rotate the switch into place until it locks.
Do this to both boards (or more if you want more)!
Test that by pressing the remaining micro switch the light comes on and you can record using the microphone, and when pressing the switch it plays what you have recorded back. Depending on the board you purchased this could allow between 10 and 30 seconds of recording time. Playback will be quiet as there is no resonance box behind the speaker(Pic2)
Box Holes:
Cut 2 x 25mm holes into the box top to allow each button to be fitted, ensuring there is room for both buttons side by side with a gap between.
Secure the buttons into place using the retaining nut.
Test the unit, you will now find it is considerably louder as the pencil case acts as a resonance box behind the speaker, ensuring sound and clarity.
Simply record what you wish to be repeated for each of the buttons, and erase and change as you wish(Pic3)
2 Buttons can be simply Yes and No, alternatively add more buttons, or smaller buttons for a more words. The total cost was less than $30. for the whole unit with parts like the buttons and circuit boards available of Ebay and Amazon for only a few dollars, you can also use a small battery pack to allow the batteries to be easily changed as they get weaker.
