The Speaker
The Speaker is a software speech synthesizer for the Amstrad. It was published as a BASIC listing in French Magazine CPC Infos by Xavier Grossetete in 1991. This was based on a port of the Spectrum Speech program by Superior Software, published in 1986. The Speaker was then retyped by NoRecess in 2011 and distributed as a DSK file called -SAY.dsk.
The original code has been disassembled by CPSoft and has been converted into a ROM extension format. The Z80 assembly source code will also be available to download.
Usage
Add SpeakerROM.rom to a ROM bank on your Amstrad emulator.
Type |SPHELP to view the usage instructions.
|SAY,"HELLO WORLD" - Say a phrase. The program converts the string into phonemes.
|SPEAK,"/HEH4/HEH3/HEH2/HEH1/" - Say a phrase without the program converting phonemes.
|SPEED,1-20 - Alter the speed of the speech
|CENTRE (or |CENTER) - Output speech using channel B

|RIGHT - Output speech using channel C
|SPON - Turn on automatic text to speech output (&BB5A jumpblock patched)
