Speech is an integral part of the game. It makes it much more fun to play. One newer machines speech should already be installed and work with no problems. You only need to read this if speech does not work and/or you have an older machine with an older verison of the OS/System.
Here is a brief explanation of the speech possibilities.
Macintalk
This is included with the game. This is the original. It is not supported by Apple. It has not been supported for a long time. It works on all Macs except the Power Macs. Do not try to use with Power Macs!
Speech Manager (with Macintalk 2 or Macintalk Pro or both)
The Speech Manager is the new speech supported by Apple. It is MUCH better. To use the speech manager you need either Macintalk 2 or Macintalk Pro in addition to the Speech Manager installed in your System/Extensions Folder. Macintalk 2 works on all machines that the game works on. Macintalk Pro only works on the faster machines.
Macintalk 2 comes with "Fred" included. It is my understanding that 7.5.3 includes a lot of different voices that Macintalk 2 can use in addition to "Fred".
David's Backgammon supports ALL of the above. If they are installed correctly on your computer then David's Backgammon will find them and will make them available in the speech sub menu.
Sound Manager 3.0
It is recommended that you have Sound Manager 3.0 installed in your System/Extension folder.
It is strongly recommended that you install either the orginal Macintalk or the new Speech Manager software with either Macintalk 2 or Macintalk Pro.
The Speech Manager, Macintalk 2 and the various voices are included with System 7.5 or later or from Quality Computers ( 1-800-777-3642). The Speech Manager is part of the PlainTalk software.
The new Speech Manager has some very nice and entertaining voices included. It is the recommended choice.
Macintalk has been included on this disk. If you wish to use it and don't have a Power Mac, place it in the same folder as the game or in the System folder.
