VOCD and Target_Child tag - further info

[Katie Alcock]

I've now managed to reproduce my non-running error which is:

vocd +t#Target_Child

(the formatting of the +t switch being taken from the formatting in
freq/kwal etc.)

Dear Katie,
I am not familiar with any version of the +t switch that uses the
# sign. The easiest way to have VOCD focus on only Child utterances
is to call the Target_Child "CHI" and use the +t*CHI switch.

If you just type "freq" or "kwal" to get the switches, from within
CLAN, you get the line

+/-t#Target_Child - select target child's tiers

+t#Target_Child works for these commands (I haven't tried it for
others) so I assumed it would be the correct format.

However other formatting of the Target_Child switch still doesn't work
with VOCD - is this expected, given that it does work with most
commands?

(We use children's names because our samples include speech from
multiple children, it is easier on the transcribers, and we can if we
wish re-designate a target child if we focus on a different age group
at a later date, since we obtain the other children's ages where it's
possible to do that. I could I suppose search and replace the child's
name but as I have already included a role of "Target_Child it would
be nice to know if it works).

Dear Katie,

Oh, I see what you mean now. Yes, that #-based selection works for
FREQ and not for VOCD. The trick with VOCD is that the core code
there was written at Reading and Leonid can only handle changes that
are relatively external to the core code. However, it may be possible
to add this feature. However, if you use the +t*CHI format, that
would work directly.
