Dear Mark and Alex

I've looked through your emails and Alex's web pages. It looks
good to me. Here are a few points for what they're worth:

1. When Andrew Slater and Nick Youd worked on a parser for Infovox, they
chose what they described as a relatively flat system, and used Bachenko
and Fitzpatrick (1990) Computational Linguistics 16(3) as a springboard.
Are you also going for a flat structure (not as rich as for recognition,
e.g.), or are there reasons not to?

2. Mark's document -- very positive reaction: just 2 points

(a) paragraph 7: An algorithm searching for spectral similarity could be
useful, but I think we need a formalism to address asynchronous points
too. If there's a formal phone onset time, then subphone aysnchronies can
be formally defined as 0 plus or minus n sampling units.

(b) Paragraph 8: We need a 4-5 ms sampling frame to do consonants.

Sarah
