I am sure there was a piece of software for the Amiga 1200 that by inputting written words the Amiga would talk ,but I cant for the life of me remember what it was or what it was called ,any one have a clue please ,best wishes Brian
If I remember correctly, you could invoke speech from the CLI by typing the "say" command. But you also need "speak-handler" and must mount the "SPEAK:" device before your Amiga will output any speech. The translator.library also plays a part but I can't remember the details after so many years.
I.e.
CLI> say "Hello world"
The output sounded fairly synthetic but it did a very good job of translating text to speech. It sounded very much like the speech that the C64 could output and I think the Amiga speak: device was based on code from the C64.
