It's the only accessible Linux for Chinese blind. The Linux distribution is based on Ubuntu LTS. I install Chinese TTS in it, hack input method to be readable and make some essential configuration for Chinese locale in the distribution. I also wrote some tutorials to teach blind people how to install and use it.
I am the main contributor of Chinese support of eSpeak and author of Ekho TTS (
http://www.eguidedog.net/ekho.php). These are the only two open source TTS that support Chinese.
The description code were not in speech-dispatcher or any TTS. It locates in ibus. I hack ibus and re-install it in my Linux distribution. The description is not standard and to be improved. But I don't think there a standard.
I would like to repleased a new version of eGuideDog Linux at April after Ubuntu 18.04 released. Then I will improve the description. It needs much of work because I need to go though all Chinese characters. When the description is good enough, I think it would be better to push it to Orca so it become default part of Orca.
