The texts and speakers in TIMIT have been subdivided into suggested training and test sets using the following criteria: 1- Roughly 20 to 30% of the corpus （语料库）should be used for testing purposes, leaving the remaining 70 to 80% for training. 2- No speaker should appear in both the training and testing portions. 3- All the dialect（方言的） regions should be represented in both subsets, with at least 1 male and 1 female speaker from each dialect. 4- The amount of overlap of text material in the two subsets should be minimized; if possible no texts should be identical. 5- All the phonemes should be covered in the test material, preferably each phoneme should occur multiple times in different contexts.
