I've made my StarBlast game work with either the eSpeak or Festival speech synthesiser (you can alter my source code to change from Festival to eSpeak).
https://www.qb64.org/forum/index.php?topic=576.msg4272#msg4272My questions are:
1) Can you hear the voice when the speaker is identified as CENTRAL COMMAND near the bottom of the screen?
2) How can I change to a different Festival voice using SHELL? I've tried, but I can do it only at the command prompt (in Ubuntu).
I hope you like my game. Thanks!
