This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

The Acorn Speech System - by - Gordon Horsington
----------------------------------------------------
Module 0. Introduction.
-----------------------
The Acorn Speech system can be fitted into any of the BBC B series of
computers. The speech upgrade cannot be fitted into either the Master
computer or the Master Compact. The speech upgrade kit contains two chips
(a Texas Instruments TMS 5220 speech processor and a Texas Instruments
TMS 6100 word PHROM, known as word PHROM A), an extension socket for extra
word PHROMs, a keyboard connector, two resistors and two capacitors. The
upgrade kit can be bought for under twenty pounds.
If you have an issue 2 or 3 BBC B computer you should have the upgrade
fitted by your computer dealer because the main circuit board will have to
be modified. If you have an issue 4 or an issue 7 BBC B or a BBC B+ you
can easily fit the two speech chips yourself. As well as fitting the two
chips you can also fit the optional extension socket for extra word
PHROMs. This is supplied with the upgrade kit and has to be soldered onto
the keyboard. This will be another job for your computer dealer if you
don't have much experience of working with a soldering iron. You should
not attempt to fit it yourself unless you are sure that you can do the
work. It is quite tricky to fit but the extension socket is only required
if you intend to use extra word PHROMs.
The Acorn word PHROM A has the serial number VM6100A. There are four other
16k word PHROMs supplied by Texas Instruments all of which can be used
with the Speech System. These alternative word PHROMs are:
VM61002 General Vocabulary
VM61003 Weather/Time Vocabulary
VM61004 Military Vocabulary
VM61005 Avionics Vocabulary
The Acorn word PHROM A is the only one with an English accent. The other
four listed above have an American accent. In order to use an alternative
word PHROM it is necessary to make a small printed circuit board to carry
the word PHROM and then plug the PCB into the extension socket on the
keyboard. The board will need to make the following connections between
the keyboard socket and the word PHROM pins (the socket key is between
sockets 2 and 3):

If you really need to use an alternative American vocabulary you may find
that it is worth all the trouble of making a PCB to hold an extra word
PHROM. I have been unable to find a supplier of PCBs to hold extra word
PHROMs and it seems that if you want to use one of them you will have to
make the PCB yourself.
An easy-to-install alternative to extra word PHROMs has been produced by
Computer Concepts. They market an excellent sideways ROM Speech System
which can be used to control the speech processor and costs about the same
as two extra word PHROMs. This system can be used without a word PHROM of
any sort and can be supplied with the TMS 5220 speech processor if the
Acorn Speech upgrade has not been fitted into your computer.
The Computer Concepts Speech System uses the TMS 5220 speech processor to
create the phonemes which produce speech. It produces high quality speech
with a neutral accent and requires very little knowledge of programming.
The system can be made to sing in a major scale (no sharps or flats) and
can translate text into speech. This system is undoubtly more versatile
than using extra word PHROMs.
If you have bought the Acorn speech upgrade kit and want to use a larger
vocabluary than the one supplied on word PHROM A it is not necessary to
buy any extra word PHROMs or sideways ROMs. It is quite easy to produce a
much larger vocabulary than the 165 words supplied in word PHROM A without
any extra hardware, ROMs or PHROMs. This series of tutorial modules will
teach you how to program the TMS 5220 speech processor directly and show
you how to extract speech data from word PHROM A and use it to create an
almost unlimited number of new words.
There are seven modules in the Speech System block of the Opcodes series.
The modules are in files named T/SPK00 to T/SPK06. The following topics
will be covered in these modules.
Module 0. This module. Introduction.
Programs: EQUDEMO EQUATE
Module 1. The speech synthesiser commands.
Programs: BEWARE PENCE CLOCK TONE1
Module 2. The Acorn word PHROM A.
Program: REVERSE
Module 3. Using the Read and Branch instruction.
Program: BRANCH
Module 4. Searching the word PHROM for word names.
Program: SEARCH
Module 5. Using the Speak External command to extend the vocabulary.
Programs: ADDRESS CREATE MOUTH
Module 6. Creating new words with the Speak and Reset commands.
Programs: ADDRESS CHOPUP TELSOFT
The later modules develop the ideas and techniques described in the
earlier modules and for this reason the series needs to be worked through
from beginning to end rather than used as a reference guide to the speech
system. You will need to refer to the Acorn Speech System User Guide
throughout the series.
When you have completed the speech modules you should be able to modify
the demonstration programs to enable your speech system to say anything
you want it to say. You will not need to use any software other than that
provided with the modules and you should find that good quality speech can
be easily produced without any additional hardware or firmware.
The example programs have been written in BASIC 2 Assembly language. The
BASIC 2 or BASIC 4 Assembler is essential for serious machine code work.
If you have to use BASIC 1 then the equate pseudo-operation commands are
not available and have to be simulated using the OPT FN command.
This can be done by loading a program into memory and replacing every
equate pseudo-operation command with its equivalent OPT FN simulation.
This replacement is demonstrated in the program EQUDEMO.
10 REM: EQUDEMO
20 DIM mcode &100
30 FOR pass = 0 TO 3 STEP 3
40 P% = mcode
50 [ OPT pass
60 OPT FNequb(&12)
70 \ OPT FNequb(&12) is the
\ BASIC 1 equivalent of EQUB &12
80 OPT FNequw(&1234)
90 \ OPT FNequw(&1234) is the
\ BASIC 1 equivalent of EQUW &1234
100 OPT FNequd(&12345678)
110 \ OPT FNequd(&12345678) is the
\ BASIC 1 equivalent of EQUD &12345678
120 OPT FNequs("hello")
130 \ OPT FNequs("hello") is the
\ BASIC 1 equivalent of EQUS "hello"
140 ]
150 NEXT
160 END
170 DEFFNequb(byte)
180 ?P%=byte
190 P%=P%+1
200 =pass
210 DEFFNequw(word)
220 ?P%=word MOD 256
230 P%?1=word DIV 256

280 P%=P%+4
290 =pass
300 DEFFNequs(string$)
310 $P%=string$
320 P%=P%+LEN(string$)
330 =pass
After making alterations similar to those illustrated in lines 60 to 130
of the program EQUDEMO, you can *EXEC the file EQUATE which will add the
definitions of the simulated equate pseudo-operations onto the end of the
program in memory. This will save you the effort of typing in the equate
functions for every program.
REM: EQUATE
30000 END
30010 DEFFNequb(byte)
30020 ?P%=byte
30030 P%=P%+1
30040 =pass
30050 DEFFNequw(word)
30060 ?P%=word MOD 256
30070 P%?1=word DIV 256

30130 =pass
30140 DEFFNequs(string$)
30150 $P%=string$
30160 P%=P%+LEN(string$)
30170 =pass
Making these modifications will allow all the programs to assemble
properly using BASIC 1, but I feel sure that replacing the BASIC 1 ROM
with either BASIC 2 (or BASIC 4 if you also install an R65C02 CPU) is far
better than patching the BASIC 1 assembler in this way.
