# Shareable Libraries

DECtalk Software APIs are available to programmers in two shareable libraries.

· libtts.so contains device independent DECtalk Software routines.

· libttsmme.so contains the DECtalk Software library that requires Multimedia Services for Tru64 UNIX.

As in the case of the header files, if you want to use DECtalk Software to write an application that produces buffers of synthesized speech, then the program is linked with the libtts shared library. If, on the other hand, you want to use the Multimedia Services for Tru64 UNIX to communicate with the audio subsystem then the application has to be linked with the libttsmme shared library.
