Question for Doug Lee or anyone else willing to answer.
Java Access Bridge, J A B 2.x.x must be enabled via the Windows Accessibility
Control Panel or executing the java app called JABswitch.
Below is an SSB Bart Group link that talks about this.
https://www.ssbbartgroup.com/blog/2012/08/30/jre-7-update-6-now-comes-bundled-with-the-java-access-bridge/
I don't recall Java Access Bridge 1.x.x requiring that it be enabled.
Is Java Access Bridge enabling new to 2.x.x?

Date: Sun, 24 Feb 2013 16:52:55 +0700
Hello all
I need to say a message with a specific synthesizer and voice. Actually now I
am having to switch to my synthesizer and voice manually before saying my
message and switch back to default voice but I do not like this way.
I found a function: SayUsingVoice
According to fsdn book, I can use that function but I do not find any parameter
for my synthesizer and voice, so I do not know how to use it.
Does anyone know to use it?
Thank all.

Dung Nguyen.

Hi
I have a same problem related to delay event. Could you please take a look
it at and give me any idea?
My context is: I need to say 2 message and have a delay between them, so I
created a snip of code as below:
-------
Say(message1, OT_STRING)
DELAY(10)
Say(message1, OT_STRING)
-----
It seems to delay function starts counting time after message1 is started
spoken, not after message 1 is spoken completely. So if the message 1 is
long, then delay function does not take any effective.
I need a delay period between finishing saying message 1 and starting
saying message 2.
Do you have any idea for my case?
Thank so much.
Regards,
Dung Nguyen.

Trivia Question, in the folowing snippet of code, which message do you think
will get spoken first? Hello? or Goodbye.
The winner will recieve an all expenses paid trip to nowhere, and a cracked
version of NVDA.
Script Test ()
; start this from the keyboard
ScheduleFunction ("HelpTest", 1)
delay(50)
SayString ("goodbye")
EndScript
Function helpTest ()
SayString ("hello")
EndFunction
The answer? Are you sure you want to know? You're not going to like this.
Wrong. Good bye is spoken first, because the jaws script engine is busy
processing the delay statement when the scheduled function comes due. So,
the scheduled event must wait for the main script to finish, even though it
is due sooner.

Hi Dung,
Sorry, but I think that function is not intended for what you are looking
for...
The choice of voices that it can use, are only from the currently running
synthesiser, and are the global , keyboard, message & Jaws cursor voices as
listed below.
See the extract from the Freedom Scientific FSDN below...
The constants referred to are in the HJConst.jsh file, which is in the
allUsers folder of Jaws.
FSDN extract:
Function: SayUsingVoice
Description
Speak a string of text using a specific synthisizer voice.
Returns
Type: Void
Parameters
Param 1:
Type: String
Description: Type in the constant representing the voice to be used. These
constants are defined in the file hjconst.jsh and are listed below:

Subject: [jawsscripts] Timing rules for JAWS scripts
Prompted by a few messages about scheduleFunction and delay()
surprises last night, I offer the following set of perhaps interesting
facts about timing in JAWS scripts:
1. ScheduleFunction() functions do not make one function interrupt
another as far as I can tell:
script test()
sayString("alpha")
scheduleFunction("test1", 0)
sayString("beta")
delay(50)
sayString("gamma")
endScript
function test1()
sayString("delta")
endFunction
will say "delta" after all the other sayStrings, because the scheduled
call will not occur until after the test() script is finished.
2. The exception (isn't there always an exception?) is for events: If
you have a delay() in a script or function, an event like
FocusChangedEvent can fire during that call. This is why delay() now
has the second parameter that you can use to prevent this.
3. Delay() can be cut short, but pause() cannot. If you press a key
while a delay() is running, it can return instantly. Not only that,
but tests I ran years ago showed that one key press will make all
further delay() calls effectively do nothing, i.e., not delay at all,
until the key buffer is cleared. Pause(), on the other hand, is always
going to cause a momentary suspension of script processing.
4. There is no function in JAWS scripting that lets you know when
something has finished speaking:
script test()
sayString("A dozen, a gross, and a score, "
+"Plus three times the square root of four, "
+"divided by seven, "
+"plus five times eleven, "
+"Equals nine squared plus zero, no more.")
scheduleFunction("test1", 20)
endScript
function test1()
sayString("Wait wait wait, um, I can't do math that fast!")
endFunction
Unless your synth is speaking fast enough to set off the kitchen smoke
detector, two seconds will be up a ways before "no more" is spoken.
test1() will be called while speech is in progress, and its message
will be queued for speaking and will speak immediately after the long
script sayString is finished. I know of no safe way to cause a
two-second delay between the end of the long sayString's speaking and
the start of another message.
By the way, I never knew who first penned that limerick, but I love
it, and it does work out mathematically. It is not my invention.

Subject: [jawsscripts] Re: Timing rules for JAWS scripts
This is a workaround/hack, but what about the following approach for
knowing when speech has stopped?
Instead of using SayString() or similar, define a function named
something like SayStringAll(), which is passed the string and puts it in
a user buffer that is then spoken with SayAll(). Have a global
true/false variable that indicates whether speech is in progress. Set
the variable to true just before the SayAll(). Define a
SayAllStoppedEvent() function that clears the user buffer and sets the
variable to false.
Can that global variable then be tested within scripts to determine
whether speech is in progress? If a specific delay is desired after a
string is spoken, might a global variable be set by the SayStringAll()
function before executing the SayAll(), and then that delay be executed
by SayAllStoppedEvent() before it returns?

Subject: [jawsscripts] Re: Timing rules for JAWS scripts
Way to think outside the box there!
That might work, if one is willing to put up with a few side effects
of using a user buffer. I don't actually know how precise the
SayAllStoppedEvent's call time is relative to actual speech cessation
though.
The user buffer side effects are these: Possible multi-second delay if
visual display of user buffers is active, the very visual display
itself, and pseudo focus change activity caused by the buffer's
display. Interruption of speech should be fine, but in all cases of
course, you have to worry about closing the buffer on completion as
well. I recommend temporary disabling of user buffer display during
this process. You could probably re-enable display right after
userBufferActivate() safely, but I haven't tested that theory.
Fascinating approach though.

No, in fact, this is what has been discussed before on this list. WE don't
have a convenient way to determine when the synthesizer has finished
speaking.
The signal is certainly there, somewhere, but we don't seem to have a good
way at getting to it.
The method I have used in the past to try to get around this involved
analyzing the message to be spoken, and calculating a delay time based on
that message.
Somewhere, I have a piece of code that follows the pronunciation rules of
the English language, and analyzes a piece of text to generate a syllable
count. I wrote that for a different purpose, but found it useful here. I
then used the syllable count, in conjunction with speech rate, to create a
delay interval time.
The more syllables, the longer the delay.
That technique works, sort of, but you would have to write a different
analyzer for each language, and all of that.
Maybe somebody here will notice some clever hook in a sapi5 dll or something
that will let us query the synthesizer to see if it has finished.

Hi
I have a same problem related to delay event. Could you please take a look
it at and give me any idea?
My context is: I need to say 2 message and have a delay between them, so I
created a snip of code as below:
-------
Say(message1, OT_STRING)
DELAY(10)
Say(message1, OT_STRING)
-----
It seems to delay function starts counting time after message1 is started
spoken, not after message 1 is spoken completely. So if the message 1 is
long, then delay function does not take any effective.
I need a delay period between finishing saying message 1 and starting
saying message 2.
Do you have any idea for my case?
Thank so much.
Regards,
Dung Nguyen.

Trivia Question, in the folowing snippet of code, which message do you think
will get spoken first? Hello? or Goodbye.
The winner will recieve an all expenses paid trip to nowhere, and a cracked
version of NVDA.
Script Test ()
; start this from the keyboard
ScheduleFunction ("HelpTest", 1)
delay(50)
SayString ("goodbye")
EndScript
Function helpTest ()
SayString ("hello")
EndFunction
The answer? Are you sure you want to know? You're not going to like this.
Wrong. Good bye is spoken first, because the jaws script engine is busy
processing the delay statement when the scheduled function comes due. So,
the scheduled event must wait for the main script to finish, even though it
is due sooner.

Good information,, and exactly what I have seen as well.
I have always been curious about the difference between pause(), and
delay(1).
The FSDN seems to suggest that pause returns control back to the OS for
scheduling, to let other apps run, where delay does not.
I have never determined if that is the case or not. But, it seems like an
important distinction.
But, I certainly have seen the keyboard cancellation of delay that you
mentioned. Kind of handy, actually, and occasionally amusing.
So, if you really want to wait 2 seconds, and you don't want the keyboard to
cut it short. put Pause() inside a "for" loop and run it 20 times.

Subject: [jawsscripts] Timing rules for JAWS scripts
Prompted by a few messages about scheduleFunction and delay()
surprises last night, I offer the following set of perhaps interesting
facts about timing in JAWS scripts:
1. ScheduleFunction() functions do not make one function interrupt
another as far as I can tell:
script test()
sayString("alpha")
scheduleFunction("test1", 0)
sayString("beta")
delay(50)
sayString("gamma")
endScript
function test1()
sayString("delta")
endFunction
will say "delta" after all the other sayStrings, because the scheduled
call will not occur until after the test() script is finished.
2. The exception (isn't there always an exception?) is for events: If
you have a delay() in a script or function, an event like
FocusChangedEvent can fire during that call. This is why delay() now
has the second parameter that you can use to prevent this.
3. Delay() can be cut short, but pause() cannot. If you press a key
while a delay() is running, it can return instantly. Not only that,
but tests I ran years ago showed that one key press will make all
further delay() calls effectively do nothing, i.e., not delay at all,
until the key buffer is cleared. Pause(), on the other hand, is always
going to cause a momentary suspension of script processing.
4. There is no function in JAWS scripting that lets you know when
something has finished speaking:
script test()
sayString("A dozen, a gross, and a score, "
+"Plus three times the square root of four, "
+"divided by seven, "
+"plus five times eleven, "
+"Equals nine squared plus zero, no more.")
scheduleFunction("test1", 20)
endScript
function test1()
sayString("Wait wait wait, um, I can't do math that fast!")
endFunction
Unless your synth is speaking fast enough to set off the kitchen smoke
detector, two seconds will be up a ways before "no more" is spoken.
test1() will be called while speech is in progress, and its message
will be queued for speaking and will speak immediately after the long
script sayString is finished. I know of no safe way to cause a
two-second delay between the end of the long sayString's speaking and
the start of another message.
By the way, I never knew who first penned that limerick, but I love
it, and it does work out mathematically. It is not my invention.

SAPI5 is certainly capable of telling you this sort of thing, but I am
pretty sure you have to have a reference to the voice instance that is
speaking (meaning you would have to get it from jaws, rather than by
just crating a SAPI voice instance yourself).
And even then that would only work if the preferred voice is SAPI, it
would do nothing for those using eloquence or realspeak direct or
vocalizer voices (which I am certain all have means to signal this
information, but again jaws does not make it available).
