Publishing Topics

• speech_recognition/vosk_result -> vosk_node.py publishes a custom "speech_recognition" message
• speech_recognition/final_result -> vosk_node.py publishes a simple string with the final result
• speech_recognition/partial_result -> vosk_node.py publishes a simple string with the partial result
• tts/status -> tts_engine.py publishes the state of the engine. True if it is speaking False if it is not. If the status is true vosk_node won't process the audio stream so it won't listen to itself
• tts/phrase -> tts_engine.py subscribes to this topic in order to speak the given string. Name your desire and it shall be heard by all in the room..

ros-vosk's Issues

Can't add new model

when executing vosk_node.py after changing the model name in param , iam getting this message
""Unable to register with master node [http://localhost:11311]: master may not be running yet. Will keep trying.""
i downloaded a new model using roslauch ros_vosk ros_vosk.launch and after downloading its showing error

Import Vosk into ROS distribution

I created a pull request

ros/rosdistro#31148

but it seems we need to make sure we are packaged on Debian/Ubuntu first

Inconsistent package names

Hi there, I was trying out the ros-vosk, and I found some package names are inconsistent (it is called ros_vosk in some places and vosk_ros in others, I guess due to the port from https://github.com/a-prototype/vosk_ros (I understand this repo will take over @a-prototype 's one).

On another note, it might be good to put the installing line as "https://github.com/alphacep/ros-vosk.git ros_vosk". Otherwise, there are issues with the folder named ros-vosk and the package ros_vosk.

can not install ros-vosk in ros noetic

I can't seem to find the ros-noetic-ros-vosk package.
Is there anything I've forgotten to do?
