Subject: voice: allow rendering actor to be specified as by 'renderer/name'.
X-Git-Tag: accepted/tizen/ivi/20140614.213511~33
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cff2933f0768edbd245960af013749d98e7d1670;p=profile%2Fivi%2Fspeech-recognition.git

voice: allow rendering actor to be specified as by 'renderer/name'.

We'll need a better approach for selecting actors than a brute
force linear search. Some renderers (eg. the soon to be committed
espeak-based one) provide a huge number of voices. A linear search
over such a number for every render request is not a good idea...
