Is there a simple speech recognition program where you can say a command and that that command will be executed in the terminal? It must be simple to install/setup/configure and it must be a small package because don't have much space left. I am running Lubuntu 14.10 on my EEE PC 701.
Apparently not - there are recognition engines (Sphinx, Julius) but all require a library of speech / meanings - there are several expensive ones out there, and a project to crete an open-source one (which looks to be dead).
Apparently Julius works if you speak Japanese. Sphinx appears perhaps more promising, with updates this year. I don't think it looks simple though.
Disappointing...
You can use CMUSphinx for that. Tutorial with basics is here.
The simple way to configure this would be to use small Python program. You can find example of voice spotting with Python on CMUSphinx github.
