Hi,

does anybody know which symbols are allowed to use as a phonem abbreviation?

I'm asking because I want to use SAMPA (instead of IPA) as my phonem syntax but I noticed that htk doesn't like digits and also the "?" seems to make some trouble!

And I don't know if the program can make differences between the upper and lower case! Also I'm not sure if the ":" symbol can cause any problems!

Hi Nick,

Searching the HTK mail archives is helpful sometimes:

[   ] htk-developers.mbox     13-Mar-2009 18:12  3.2M  
[   ] htk-users.mbox          13-Mar-2009 18:12   24M  

 

This post explains things a bit:

You can use arbitrary strings as phone labels in HTK. I'd suggest you
restrict them to US-ASCII characters though. HTK has no list of
allowed phone symbols (IPA or others) built into it.

You could call your phones p1, p2, p3,... if you really wanted to.

See also section "4.6 Strings and Names" of the HTK book.
