Z h d d 6d d 6d d 6d d 6Z d Z e d j o e n d S( su Python wrapper for Emacspeak speech servers.
The emacspeak TTS server provides a simple but powerful and
well-tested speech-server abstraction. That server is implemented
as an external program (typically in TCL). This wrapper class
provides Python access to available Emacspeak speech servers.
Initially, this class will provide Python access to the TTS
server commands. Over time, this module may also implement
functionality present in Emacspeak's Lisp layer ---specifically,
higher level TTS functionality provided by the following
emacspeak modules:
0) dtk-speak.el
1) emacspeak-pronounce.el
2) accs-structure.el

Class Variables:
location -- specifies directory where Emacspeak
speech servers are installed.
config -- dictionary of default settings.
Speaker objects can be initialized with the following parameters:
engine -- TTS server to instantiate. Default: outloud
host -- Host that runs server. Default: localhost
settings -- Dictionary of default settings.
