Построение flite_main.exe из каталога flite-1.2-release\main
Откройте файл flite_main.c в MS VS 6.0 и выполните компиляцию. Среда разработки создаст файл проекта. Для успешной компиляции необходимо добавить несколько файлов в проект, а также внести изменения в файл flite_main.c.
В итоге вы получите полностью работоспособный файл flite_main.exe.
Примеры запуска из командной строки:
flite_main.exe --help
flite_main.exe --version
flite_main.exe -t hello world -o text.wave
flite_main.exe text.txt

Новый файл проекта flite_main.dsp

Проект голосового движка FliteCMUKalDiphone из каталога sapi также собирается без проблем в MS VC2008Exp c установленным sdk6.0. Необходимо прописать пути к каталогам установки sdk, а также добавить в подпроект flite файл au_wince.c
Для построения в vc 60 потребуется установить sdk 5.1.
