[EAS] Why we need Text-To-Speech

[Ed Czarnecki]

Similarly, the DASDEC and R189 OneNet provide a standard TTS voice, and two
optional additional voices (male and female).  Each specific voice has a
lexicon record that allows some customization of word and abbreviation
pronunciation,  But, as was previously stated, lexicon guidelines (maybe not
even files, but guidelines) would be at a state, regional or national level.

This is all to say, there are some broad approaches and standards that may
already be in place in the CAP EAS manufacturer community, even if it is
organic or coincidental.  Identifying these commonalities may be something
that a group (ECIG? FCC CSRIC?  Other?) could do to give comfort to the FCC
about quality and reliability of TTS in CAP EAS devices.  Not that TTS is
perfect, of course.  But, as ECIG noted in our ex parte filing with the FCC,
it is at a minimum a necessary fallback should the human/synthetic voice
audio file be absent or unusable.

Yes.  I know you are kidding, but here's as good a place as any to say:

Click Cap Settings on the ENDEC's home page, then retrieve or restore
lexicon.  You'd add things like:
"9-1-1" = "nine one one"
"911" = "nine one one"

There is a second internal lexicon that Sage sets, where global corrections
are placed, such as "endec" = "\fE-n-d-`E-kh"

This is not to say that each and every radio station is responsible for
setting these. The lexicon files should be developed at the country or state
level, and made available for downloading.  Exactly how this gets done, and
who will do it will be different for each area.
