Testing DECtalk native "singing" mode command
The first version is produced in normal text to speech, the second version is done by adding the "singing" command with the lower pitch possible. ([_<0,1>])
Here is the spoken text read from the SD card :
1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey the orders given to it by human beings, except where such orders would conflict with the first Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
