| BRLTTY speech driver for "GEnericSay" |
| |
| This driver is intended to be used with any speech synthesis program |
| like the rsynth package. |
| |
| This is preliminary code, still experimental. Need improovements... |
| |
| From the perspective of brltty: The command "/usr/local/bin/say" is |
| invoked with no arguments, and each text string which is to be spoken is |
| written to the standard input of that command. A period and a new-line (in |
| that order), i.e. ".\n", are appended to each text string as this is a |
| reasonably standard way to instruct a speech synthesizer to start speaking |
| right away. When the speech is to be stopped, i.e. interrupted and |
| flushed, then the standard input of the command is closed. The command is |
| restarted the next time there is something else to speak. |
| |
| From the perspective of the command which must be supplied by the user: It |
| must be called "/usr/local/bin/say". It is invoked without any arguments. |
| It must first send any required initialization sequences, and then copy |
| its standard input, to the speech synthesizer. Upon detecting end-of-file |
| on its standard input, it should send the "shut up" sequence, followed by |
| any required shut down sequences, to the synthesizer. |
| |
| The subdirectory "commands" of this directory contains examples of |
| "/usr/local/bin/say" scripts for various speech synthesizers. |
