Software

  • |SAY,@<string> - Converts a string af ASCII text to speech
  • |ECHO,<mode> - Activates text to speech conversion on text printed to the screen.
  • |APHONE,<allophone>[,<allophone>] - Send allophones directly to the interrupt driven allophone buffer.
  • |ROOM,@<value> - Find out how many free locations in the allophones buffer.
  • |QUIET - Clears the allophone buffer.
  • |SPON - Activates the speech interrrupt event.
  • |SPOFF - To prevent output of data from the allophone buffer.
  • |SPSTATUS,@<value> - Read the status of the speech processor.

Technical Specs.

The clock frequency (passed to the speech chip) is fixed, the exact frequency is unknown (?)

Uses I/O port: #FBEE

Port FBEEh READ: 

 bit7   status 1 (0=busy, 1=ready/data request)
 bit6   status 2 (used by 3D Stunt Rider, Roland in Space, Glen Hoddle)
 bit5-0 unknown/unused
 (the above status bits are probably the /LRQ and SBY pins)
 (unknown which is which one though?)

Port FBEEh WRITE: 

 bit7-6 unknown/unused (should be zero)
 bit5-0 allophone number
