I’m not sure if anyone else uses a TTS extension but I certainly would like to be able to use one. The one I use is “TTS Reader X In-Page Text to Speech.” Not sure if someone has a better one though.
Thanks for the request. Text to Speech is already requested and listed here:
Yes, please add a text to speech function. Basically, you use the mouse to highlight text in the browser and then hit a hot-key to have the computer read the text. Attached are two examples. One for a chrome plug-in by TTSReader.com. The second example, uses and obsolete version of NaturalReader (R11) with the free Microsoft David voice.
