1.1.5 is *very* old. Try version 1.2beta1, which might have better
project files.

If you mean the "speexdec" decoder, than yes the input must be in
Ogg/Speex format (as produced by speexenc).

Anything that was encoded with version 1.0 or later can be decoded by
any decoder version 1.0 or later. So versions don't matter unless you're
using *really* old encoders/decoders (version 1.0 was released in March
