The present series confirmed the established findings that Fo is lower in boys than in girls, even before mutation, and decreases with age; two other classical voice analysis parameters, jitter and shimmer, also showed the same behavior as described in the literature.
Included in this category is also a separate group of features constituting the voice quality parameters: jitter, shimmer[11], Hammarberg index[12], Liljencrants-Fant features[13], and spectral tilt[14].
RESULTS Change in all parameters of jitter measured with SFEMG electrodes predicted clinical change with acceptable accuracy.
The requirements of a specific set of QoS parameters (delay, jitter, packet loss, etc).
Uses of other parameters like jitter and packet loss are left as a part of future work.
Because of multihoming, different paths should maintain its parameters of jitter ratio when transmitting through the path.
Voice source parameters like jitter and shimmer change with age, but they are shown to have just a minor influence on speech recognition error rates.
Traditionally, for the feature extraction phase, one deals with such parameters like jitter [8,9], shimmer [10,11], signal-to-noise ratio [12,13], and formants [14,15].
Relative considerations include user mobility, traffic characteristics, Quality of Service (QoS) parameters (throughput, delay, jitter, etc).
