sak is a Speecher Assistive Kit which transforms your applications into multi-language speaking assisted applications. Easy and independent, you do not have to change anything in your original code. Compatible with Lazarus, fpGUI, MSEgui and console.

For Linux, FreeBSD, macOS and Windows.

You do not need external libraries like at-spi, sapi, nor do you need to install anything in your system. Everything is included in the kit.

sak uses the eSpeak and PortAudio open source libraries.

  • For sak, add sak.pas into your application-folder.
  • For sak_dll, add sak_dll.pas, uos_portaudio.pas and uos_espeak.pas into your application-folder.

In the "uses" section of your program add:
