Calculating speech rate with Kideval?

[Leonid Spektor]

Hi,

	Different analyses in KIDEVAL require counting words and utterances differently. The "Dur Words" and "Dur Utts" columns show the number of words and utterances counted for time duration analyses. If you have any utterances with no words on them, then the "Total Utts" column will have smaller number of utterances counted than "Dur Utts" column. So, for time duration analyses the empty utterance is still counted. The other DUR columns represent just what you assumed. The "Dur Words" column includes all words on main speaker tier including the words that are marker with [/], [//], [///], [/-], [/?] codes. The only "words" that are excluded from the "Dur Words" count are "0", "0word", "&word",  "xxx", "yyy" and "www".

	The bullets will be included is utterance doesn't have any words on it. You can exclude all zero words utterances from the data with this KWAL command:

kwal +x>0w +o% +o@ +d +f *.cha

and then run KIDEVAL on KWAL's output files.


Leonid.

One factor which is known to effect VOT is speech rate, so I am looking for a way to calculate this using a program in Clan. I noticed that when I ran Kideval, the output included columns for "Dur Words", "Dur Utts", "Dur Time (sec)", "Words/Time", and "Utts/Time". I was wondering if anyone could explain what is going into each of these columns, and how they are each being calculated. I am assuming "Dur Time (sec)" is the total time in seconds of all the bullets for a particular tier, and that Words/Time and Utts/Time are just the total number of words/utterances divided by the total time. I cannot figure out was "Dur Words" and "Dur Utts" contains.

If so, is there a way to exclude them? I would guess maybe the easiest thing to do would be to just change the tier name since I am only concerned with the mother's speech rate.
