Voice control (sphinx+festival)

< go back to main

Preliminary steps

We use CMU Pocket Sphinx for speech recognition developed on Carnegie Mellon University, and Festival Speech Synthesis System for text speech developed on University of Edinburgh.

Currently the ROS package pocketsphinx is available for groovy and hydro distributions. We can install it executing the next command in a terminal:

sudo apt-get install ros-"groovy or hydro"-pocketsphinx

We have to install the ubuntu package CMU Pocket Sphinx in previous ROS distributions. We will execute the next command in a terminal to install it:

sudo apt-get install gstreamer0.10-pocketsphinx

Moreover for previous ROS distributions, we have to download the ROS stack "rharmony" by University of Albany in order to integrate CMU Pocket Sphinx in ROS. We will place in the ROS workspace and we will execute the next commands in a terminal:

svn checkout http://albany-ros-pkg.googlecode.com/svn/trunk/rharmony
rosmake --rosdep-install pocketsphinx

Festival Speech Synthesis System is intigrated in the ROS package sound_play.
