At Superbooth19 in Berlin we showed a sample of the PL2 Logos prototype board. This PCB makes it a lot easier to translate English text to the allophones needed for Ploytec PL2 based speech synthesis (which is CTS256-AL2 / SP0256-AL2 emulation).
On the board, a PL2 synthesizer is already integrated, so there's no need for a separate PL2 (though it's always good to have some of those).
The included USB keyboard allows entering text, and to store / recall text from memory using function keys. Each function key can hold up to 39 letters in up to six rows.
Via the integrated USB MIDI it's possible to capture and playback the MIDI notes triggering the words. On top, you can record the many MIDI notes representing allophones, to a DAW.
Please note: The knob will be most likely missing on the final board, as it never had any functionality and is not necessary for operation.
Risks and challenges
As the technology is basically working, the task to be done is bug fixing, creating firmware update functionality, changing the PCB to potentially fit into an existing case (not included!) and getting a bunch of PCBs manufactured.Learn about accountability on Kickstarter
