Still working on this project..

My work is (almost) based on the "Talk can be cheap by Larry Dighera, published in Computers & Electronics, Februari 1983" where can be found at : http://sites.google.com/site/analogvocoderinfo/speak-spell

I'm trying to do the same as the ASM code for the Z-80 with my arduino.
See below a more readable version of the asm code.
------------------------------------------------
Z-80 PIO init  (not neeed)

Get bus state
wait until data is present (especially CNTL8 because by pressing ON, ON, GO. This leaves only the cursor on, which causes CNTL 8 to periodically go high)

Get bus state
wait until bus is clear ( CNTL8 goes Low )

Get chip select Up (CS) and reset word (0)

Clock (PDC)

Load address command (2)

Read Rom Command (8)

Speak Command (10)

Busy Command (14)

Reset Command

Clock (PDC)

Get Bus Status
Check Bit 0
if bit 0 not equal 0 then wait (bit 0 should be CNTL1 )


Reset command

Clock (PDC)

Turn Off  PIO(set Bus to 0 or High-Z)

the Rest of ASM code is not needed.
