I'm making a project that requires the user to control the computer through speech. I've seen a couple of libraries, for python, that can do this but most of the ones that I have seen are windows only. There is a library called dragonfly which seems to be very popular but I havn't seen anything telling me that it's windows only.

Are there any Raspberry Pi compatible libraries that you know of?

Yes there is Pocketsphinx to convert speech to text, that has python APIs

For installation do:

apt-cache search pocketsphinx

and install all of them.

Or I have a shorcut to do this: :D

apt-get install $(apt-cache search pocketsphinx | \
awk '{print $1}' | tr '[:space:]' ' ')

enjoy.. :)

Apologies for the late answer, but hopefully someone will find this useful.

I am using this python package on my pi, and its fantastic!

Uses the google recognition engine (the one used in chrome and "okay google") which is arguably the best for accuracy, as well as supporting free form dictation which depending on your needs, could be a real benefit (would allow for example googling a non pre-determined phrase)

Only drawback is that it requires an internet connection, and the API key is only for personal use and development, so if you are planning on launching a commercial product, this will not be viable for you.

Hope this helps.

I'm using pocketsphinx and highly recommend it for offline speech recognition. Here you have the instructions to install it: http://cmusphinx.sourceforge.net/wiki/raspberrypi

Also have a look at this question, just in case you run into the same problems I did to make it work.
