@ Hi, this is a test for SSML support in Speech Dispatcher.

@ Note that not all synthesizers (output modules) support SSML.
@ If they do not, they should still speak but should not speak any
@ of the SSML tags.

!SET SELF NOTIFICATION END ON

@ We'll begin with a simple message.

!SET SELF SSML_MODE ON
!SPEAK
<speak>
S S M L or Speech Synthesis Markup Language is an XML
language that provides authors of synthesizable content a standard way
to control aspects of speech such as pronunciation, volume, pitch, rate,
etc. across different synthesis-capable platforms.
</speak>

@ If you heard the full message, Speech Dispatcher
@ works correctly.

@ Now we will try changing the volume in mid-sentence.
$2
!SPEAK
<speak>
This sentence starts out normally, <prosody volume="loud">
but then speaks loudly,</prosody><prosody volume="soft">
and ends very softly.</prosody>
</speak>
.
+702 END

@Let's try increasing the speaking rate in mid-sentence.
$2
!SPEAK
<speak>
Political language - <prosody rate="fast">
and with variations this is true of all political parties,
from Conservatives to Anarchists</prosody> - is designed to make lies sound truthful
and murder respectable, and to give an appearance of solidity to pure wind. 
        -- George Orwell (1903 - 1950), 1946
</speak>

@ This time, slower in mid-sentence.

!SPEAK
<speak>
The secret of staying young is to live honestly,
<prosody rate="slow">eat slowly,</prosody> and lie about your age.
        -- Lucille Ball (1911 - 1989)
</speak>

@ How about changing gender in mid-sentence?
@ Since most synthesizers do not support changing voices in the middle
@ of synthesis, this may not work.
$4
!SPEAK
<speak>
Nobody will ever win the Battle of the Sexes.
<voice gender="female">There's just too much fraternizing with the enemy.</voice>
        -- Henry Kissinger (1923 -)
</speak>

@ Let's see if a change in speaker's age to 8 years old can be accomplished.
$2
!SPEAK
<speak>
<voice age="8">Human beings are the only creatures that allow their children
to come back home.</voice>

@ SSML permits sound files to be embedded in speech.
@ If this works, you should hear a man say "Yo" (as in hello).

<speak>He was heard to say
<audio src="yo.wav"/>

@ If the tests did what was expected, your installation of Speech Dispatcher
@ probably works fine. If not, there can be different causes, see
@ the documentation -- Troubleshooting. (Note that some synthesizers
@ don't support SSML. If everything else worked correctly, this is not a
@ fatal problem.).
