Examples of LAM logfile data
The following example shows a single utterance and the events that were generated in creating it. This utterance was taken from an interview with an individual who relies on AAC.
Utterance:
"It's faster than spelling everything out which is what I used to do "
LAM logfile:
16:26:05 "It's "
16:26:08 "faster "
16:26:14 "than "
16:26:41 "sp"
16:26:42 "e"
16:26:45 "l"
16:26:45 "l"
16:26:46 "i"
16:26:47 "n"
16:26:48 "g"
16:26:49 " "
16:26:58 "everything "
16:27:02 "out "
16:27:05 "which "
16:27:08 "is "
16:27:11 "what "
16:27:14 "I "
16:27:19 "used "
16:27:22 "to do "(The time stamp uses a 24-hour format, so 16:00 is 4:00 PM.)
A casual review of the logfile indicates that most words were chosen as whole words. "It's " and "to do ", a commonly used contraction and a word combination, were selected as single events. The word "spelling ", not available as a whole word, was spelled one letter at a time. The letters "sp" appear together as a single event because the AAC system used for this sample has the auto-spell feature that automatically changes mode from semantic compaction (Minspeak) to spelling.
If the word "spelling " had been generated using a word prediction system, the record for that word might look like this:
16:26:41 "sp"
16:26:42 "e"
16:26:47 "spell "
16:26:53 "spelling "The first three letters are spelled, then the word list is scanned and the root word "spell " is selected, then the derivatives of "spell " are presented in the prediction list, and finally the word "spelling " is selected.
