My CPU seems to include sse2 instructions according to /proc/cpuinfo.
Does speex provide both a sse2 and a non-sse2 implementation, and

default, then probably it would choose the non-sse2 version. I think.
This is set at compile time. Ubuntu provides two versions:

So on your system the sse2 version is used.
