To install this package, run in Emacs:
M-x package-install RET greader RET
Usage: In order to use greader, you have to install either espeak and/or speech-dispatcher and, in case of speech-dispatcher, it has to work. If external packages work properly, using greader is easy: 'M-x greader-mode <ret>' In the mode line appears "greader". Then you press 'C-r <spc>' and greader starts reading, moving the cursor at the start of the sentence it is reading at the moment. To stop reading, just press '<spc>'. If you want to change the language in which the text is spoken, press 'C-r l', and when asked to new language, digit the language iso code. If you want to cycle throwgh available back-ends, you have to press 'C-r b'. With a prefix arg, this command asks you to type a back-end name. Other features: You can set a timer, enabling it with 'C-r t'. With timer enabled, greader will read for time set in "greader-timer" variable, which is customizable. You can set a timer locally in the buffer you are reading with 'M-x greader-set-timer': Timer is expressed in minutes. There is a variant of the timer feature, called "greader-tired-mode", in which, when timer expires, and you don't press a key for a customizable amount of seconds, greader will position the pointer at last position when you pressed 'C-r <spc>'. To enable tired mode, you have to press 'C-r s'. More features are coming!
