ROS2 node that listens for a hotword in the background, e.g.hey robot, and then transcribes speech in real time.
Simply place the top commanded_stt folder in your workspace and run colcon build. You will also need to place a valid google cloud API service key in your workspace. The API key should be in a json file.
Ensure that you have a working microphone connected to your computer.
Run the following
ros2 run commanded_stt listener_node /absolute/path/to/mycroft-precise
Currently, the only recognizable hotword is the "robot say" command.
