Theora is a video format.  I think you mean Ogg, which is a container
format, and it is most commonly used for the popular Vorbis audio format.

While Ogg can be used with Speex, if you are aiming for small
sized-files and low bitrates, it's more efficient to use the plain
default container that Speex uses.  However, neither Speex nor its
native format are supported by any current browsers, to my
recollection.  You will probably need a plug-in to get Speex playback in
the browser.

However, since your files are already in low-bitrate Ogg Vorbis files,
and these are already supported in most browsers, I wonder why you need
to go to Speex at all?  Do you have any special reason to do so?
