Using the TTS SAMMY extension, you can say any word, but the only con is that you have to use the website and manually edit the code in TS to make it work, but not with this!
Using this, you only have to input the characters from the list (Press UP while out of type mode), and it will speak!
Right now it is a little iffy at times, and sometimes it won’t sound like the word, but that is due to timing issues, which I hope to fix in the near future.
Press A to start typing and press UP to see typable characters.
