Sorry we missed your post
Comfort sentences are made up of individual words in wav files
The list of sentences defines what sentences are announced
To create the sentences, al the unique words which are required for all sentences must be recorded. To minimise the size of the voice file, the number of unique words must be minimised.
Hence if you use a full sentence instead of individual words, that increases the size of the vocab file. The words are compressed in order to fit into the vocab file. Due to the compression we do not know the exact uncompressed file size that is allowed
I suggest that you use the VoiceProc and VooicePlay software tools to define your vocabulary and process the files. If they do not fit, there will be an error message. download from http://www.cytech.biz/voiceproc_software.html
