the master from his voice never belonged to HP, it is owned by Nuance after multiple acquisition. The original owner was Speech Plus, who made the CallText 5010 synth he used until this year. They indeed were looking for the masters [1]. When they found it they made a replacement for the voice synth on software running in a raspberry pi. They had just replaced the the old voice synth back in Jan. [2] Additionally, Dennis Klatt was the inventor of DECTalk, the three original voices were his own for the male voice, his wife voice for the female voice and his daughter voice for a child voice, they were named Perfect Paul, that was the default voice, Beautiful Betty and Kit the Kid.
