What reading level is Evaluation of Selected Acoustic Parameters for Use in Speaker Identification. book?
To quickly assess the difficulty of the text, read a short excerpt:
Speaking Fundamental Frequency (SFF) In all cases where SFF is employed in the discriminant analysis, the number of speakers is reduced from 50 to k3 for Group A and from 25 to 20 for Group B because the SFF vector could not be extracted for all subjects. FFI was not able to extract reliable measure of funda- mental frequency in several cases because there was excessive back- ground noise or weak signals on the recordings.
Table 3 indicates that the posterior classification of the ref- erence s...amples, 79.1% for the larger group and 68.3% for the smaller one, is well below the level achieved by the LTS vector. On this basis, SFF would not be expected to be as effective in discriminating speakers as would LTS. Further, the posterior classification of the large group is higher than for the small one indicating that for SFF, the within talker variability was less and/or the between talker vari- ability was greater for the large group. This finding was unexpected since the talkers in the group of 50 were college students who were 18-25 years of age and the group of 25 ranged in age from 25 to 45.
