Speaker speech synthesis library is a cffi interface to an adapter library which interfaces to a speech library of the platform. It enables text-to-speech and -recognition (recognition only on Mac OSX). Dependency is only cffi. The MacOSX version uses Cocoa NSSpeechSynthesizer, Windows uses Speech API, Linux uses QtTextToSpeech. For the exaxmples you need "bordeaux-threads" and "trivial-main-thread". Tested on sbcl, ecl and ccl on Linux, Mac OSX and Windows. Repository can be found here.
First open your IDE XCode/Visual Studio/QtCreator project "libspeak" and compile the libspeak.dylib/.so/.dll and copy the lib to /usr/local/lib. Windows users copy to Windows/System32. Then cd into the speaker/src directory and load your favouorite lisp and type:.
(asdf:load-system :speaker-examples)
(main)
If you just use the library then just type
(asdf:load-system :speaker)
(init-speaker)
(speak "Test")
Or add it to your .asd-file.
