speer is a C library which decodes speex files used in Siri protocol, to PCM 16bit Little Endian. It's used by Asiri, the SiriProxy plugin for multi language.
Before you install speer, you need speex, and libspeex-dev:
sudo apt-get update
sudo apt-get install build-essential pkg-config speex libspeex-dev
wget --no-check-certificate https://github.com/alotaiba/speer/tarball/release -O - | tar xz
cd alotaiba-speer-*
./configure
make
sudo make install
speer input_speex_files_dir output_speex_files_dir
The output will be inside output_speex_files_dir named "output.raw". You can use Audacity to import and play the file, or ffmpeg to encode to another format.

I would like to thank the following people, and give them credit for their awesome work, that without them, this project would probably never seen the light:
- Applidium guys - For their awesome work at reverse engineering the Siri proxy, and open sourcing their tools
- Pete (plamoni) - For creating the awesome SiriProxy, which this plugin runs on top of.
- Google - For providing the speech recognition service, though it's undocumented, but I have to give you guys credit for this awesome work.
