This directory contains the BRLTTY speech driver for the eSpeak-NG text to
speech engine. The eSpeak-NG web site is
https://github.com/espeak-ng/espeak-ng/.
eSpeak-NG comes with a simple command-line tool called espeak-ng which can be
used to test it, and to recompile modified dictionaries, etc. Please see
the espeak-ng man page for more information.
BRLTTY's configure script automatically includes this driver if the
eSpeak-NG development library is installed.
This driver recognizes the following parameters:
path
Specifies the directory containing the espeak-ng-data directory.
If not specified, the default location is used.
punctlist
Specified a list of punctuation characters whose names are to be
spoken when the speech punctuation parameter is set to "Some".
If not specified, a default list is used.
voice
Specifies a voice/language to use. The complete list of available
voices may be obtained with the command 'espeak-ng --voices'.
maxrate
Overrides the maximum speech rate value. The default is 450.
This cannot be lower than 80.
