SSIP questions

[Boris Dusek]

Hello,

I was reading the SSIP specification in doc/ssip.texi and had come to a few
points where I did not fully understand what was being said.

1. Each message queued returns a msg_id. Is there a value range for msg_id that
must be supported by the clients? (like all 64-bit unsigned)

2. Default message priority is mentioned as applying to messages with no
priority explicitely specified, but this default priority is not defined in the
text. Is it an omission, or is it implementation-defined?

3. Priority "progress" - it is said there that Speech Dispatcher detects that
the progress message is the last one by waiting. Do I understand correctly that
that the specification means that there is some (possibly
implementation-defined) timeout amount which the Speech Server simply waits to
verify no other progress message arrives from the same connection and then
speaks the progress message?

4. (just a thought) the image "figures/priorities" could list the "Important"
priority also as "Doesn't interrupt itself")

5. What is the relation between blocks and e.g. SSML? Can one do what the other
can't?

6. Regarding message blocks being treated as a single message:

I made this experiment:

01:A: SET SELF PRIORITY text
02:A: BLOCK BEGIN
03:A: SPEAK
04:A: first text
05:A: .
06:B: SET SELF PRIORITY important
07:B: SPEAK
08:B: important message
09:B: .
10:A: SPEAK
11:A: second text
12:A: .
13:A: BLOCK END

block is began by client A on line 02, with priority set to "text" on line 01.
First part of the message block is spoken after line 05. On lines 06-09,
client B sends message of priority important which should cancel the currently
spoken block from line 02. Yet second part of the block said by client A on
lines 10-12 is still said, even though the whole block should have been
cancelled.

7. The definition of parameter CAP_LET_RECOGN says that when the capital
recognition mode is "spell", the capital letters are spelled "using the table
set as CAP_LET_RECOGN_TABLE". I however did not notice what spelling "using a
table set" means, and also have not noticed what CAP_LET_RECOGN_TABLE is.

8. line 1158: event RESUME can be followed be either event END or RESUME.
My question is: It cannot be again followed by event PAUSE?

9. Scope of event notifications. E.g. with
SET SELF NOTIFICATION ALL on
does the "SELF" mean:

a. notifications for message queued by any client will be sent
to this (SELF) client
b. notifications of messages queued by this client (SELF) will be sent
to every client
c. notifications of messages queued by this client (SELF) will be sent
to this (SELF) client

I guess c. is probably right, but am not sure.



Sorry for flooding the list with so many questions, I hope somebody will be
able to enlighten me.

I also discovered a few typos/omissions/unclarities in the documentation, so I
will post a patch fixing those shortly.

Boris
