The computer downloads random audio streams from the internet. It feeds those streams into Sphinx II, which - regardless of the source - transcribes them into an English text.
Concurrently The Monolith constructs a voice by splicing the audio streams themselves into individual phonetic sounds, which it sorts into folders.
It then speaks its English text by pasting together sound files randomly drawn from the appropriate folders. As soon as a phonetic file is used it is erased.
The whole process is continuous and endless.
