A bright panel that captures the intensity of the sound. If the children speak in a low tone, the colours will be soft while, on the other hand, if the children use a higher tone, the colours will change until they reach an intensity of colour red.
Where children use a little higher or a little lower tone of voice, the colours will change.
This technology is very nice, also for children, because it offers the stimulus-response.
Thanks to the use of this technology, the children will understand that the tone of voice they are using is too high.
It is also possible to make them understand that, sometimes, there is a need to lower the tone of the voice a little bit.
