Dear Martin (and the Internationalization Working Group),

First, I would like to thank you for your very thorough review
of the SSML specification.  Given the number of specifications you
must review annually, we are pleased that you have given so much of
your time and effort to help us with our specification.

Our responses to your comments will be in two big blocks and then
a slow trickle for points still under discussion.  This email
contains the first big block of responses.  Points skipped below will
be addressed in one of the later emails.

If you believe we have not adequately addressed your issues with our
responses, please let us know as soon as possible.  If we do not hear
from you within 14 days, we will take this as tacit acceptance.  Given
the volume of responses in this email, we understand that a complete
review by you may take longer than this amount of time; if so, we
would appreciate an estimate as to when you might be able to complete
your review.
Also, since the Voice Browser Working Group's next face-to-face
meeting is next week, any concerns you have with our
responses that you could send or hint at by Wednesday, June 4 would be
especially helpful.

Once again, thank you for your thorough and considered input on
the specification.

-- Dan Burnett

Synthesis Team Leader, VBWG

[VBWG responses follow]

[3] Yes, the <voice> tag. In section 3.1.2 (xml:lang), we will note
that the <voice> element can be used to change just the language.

[4] "this set" refers to "standards to enable access to the Web
using spoken interaction" from the previous sentence. If you
believe this to be unclear, can you suggest an appropriately compact
rewording (since this is text from the one-paragraph abstract)?

[5] Accepted.

[6] Rejected.  We had already planned to rearrange sections such that
section 2 now contains the Document Form (formerly section 3.1),
Conformance (formerly section 4), Integration (formerly 3.5), and
Fetching (formerly 3.6) sections straight off. If you believe this
to be insufficient, can you propose a specific text change for section 1?

[9] Accepted.

[10] We would welcome a specific text proposal from your group. Any
language example is fine with us.

[14] Accepted.  We will amend the text to indicate that only the
Schema reference is normative and not the references to RFC2396/2732.

[15] Accepted.  All that you say is correct. We will revise the
text to clarify as you suggest.

[16] Accepted.  Thank you. We will correct this.

[18] Accepted.

[19] Accepted with changes.  This is related to point 15. We will
reword this to correct the problems you mention in that point,
but the rewording may vary some from the text you suggest.

[21] Accepted.  We will add a reference, both here and in section
2.1.6, to section 1.2, step 3, where this is described.

[23] We would be happy to accept your offer to rewrite our example
using appropriate Japanese text.

[24] Accepted.

[30] How it would be spoken is processor-dependent. The <say-as>
element only provides information on how to interpret (or normalize)
a set of input tokens, not on how it is to be spoken.
Also, as you pointed out in point 27, "format='telephone'" is merely
an example and not a specified value, at least not at this time.

[31] Both are shown as examples to indicate two possible ways it
could be done. Neither is actually a specified way to use the
element, as you pointed out in point 27.

[33] In this example, without the detail attribute a processor might
leave out the colon or the dash, or it might not distinguish between
lower case and capital letters.
However, this is not actually a specified way to use the attribute,
as you pointed out in point 27.

[34] Rejected.  As you suggested in point 27, we will be removing all
of the tables of examples in this section. If and when we re-
introduce this table, we will correct any styling errors that remain.

[35] Accepted with changes.  This statement you refer to that is present
in all of the element descriptions will be modified to more fully
describe the content model for the element, although it may not be
worded exactly as you suggest.

[36] Rejected.  We have had considerable discussion on this point.
There are two parts to our response:

(1) It is assumed that the synthesis processor will use all contextual
information already at its disposal in order to render the text and
markup it is given.  For example, any relevant case or gender
information that can be determined from text surrounding the <say-as>
element is expected to be used.
(2) The ways and contexts in which information other than the specific number
value can be encoded via human language are many and varied. For example,
the way you count in Japanese varies based on the type of object that
you are counting. That level of complexity is well outside the intended
use of the <say-as> element. It is expected in such cases that either
the necessary contextual information is available, in normal surrounding
text, as described in part 1 above, or the text is normalized by the
application writer (e.g. "2" -> "zweiten").
We welcome any complete, multilingual proposals for consideration for a
future version of SSML.

[37] Rejected.  As you suggested in point 27, we will be removing these
examples altogether. If we should decide to reintroduce them at some
point, we would be happy to incorporate a revised or extended example
from you.

[41] Accepted.

[45] What would you suggest is the normal way?

[48] Rejected.  We have other elements such as <p> with the same
potential conflict. Also, we have not particularly crafted element
names to avoid conflicts with other markup vocabularies. We see no
direct need to change this element name.

[49] Accepted.  We will clarify within the text how application authors
should handle the cases presented in the referenced email.

[50] Accepted.

[52] Rejected.  This behavior is already permitted at processor
discretion for arbitrary-length strings of text. Specific words
or short phrases can be handled in a more predictable manner by
creating custom pronunciations in an external lexicon.
We do not believe this needs additional explanation in the document.

[53] We have not had significant demand to standardize a value for
this, e.g. <voice name="kids">. Individual processors are of course
permitted to provide any voices they wish.

[54] Accepted.  If you provided us with example text in Japanese here
we would be more than happy to include it.

[55] Accepted.

[56] Accepted. The text and schema will be adjusted to clarify that
this attribute can only contain positive integers.

[57] Rejected.  This is an interesting suggestion that we will be
happy to consider for the next version of SSML (after 1.0).

[61] Accepted.  We will add such an explanation.

[62] Accepted.

[63] Accepted.  We will add this.

[64] Accepted.

[65] Accepted.  We will add this.

[67] Accepted.

[71] Accepted.  We will add an example.

[73] Accepted.  We will clarify this.

[75] Accepted.

[77] Accepted.  We will make this change.

[79] Accepted.  We will correct this.

[81] Accepted with changes.  This was accidentally left in
when originally copied from the VoiceXML specification. It
will be corrected.

[86] Accepted.  This is old text. We will clarify.

[88] Accepted.
