Questions related to Speech Science
Could colleagues provide descriptive comparisons of English to the languages named? Including consonant, vowel inventories, examination of the tonal structure of Chinese languages and so forth?
I would like to ask from all the experts here, in order to get the better view on the usage of cleaned signals which already removed the echo using few types of adaptive algorithms with method of AEC.(acoustic echo cancellation)
How the significance of MSE and PSNR can improve in the classification processes? Which i mean normally we evaluate using the technique of WER, Accuracy and may EER too.Is there any kind connectivity of MSE and PSNR values in terms of improving those classification metrics.?
wish to have the clarification on this.
I have decided to work on this topic as my thesis; however, I really do not know which sources are best and helpful to study, since I need to gain a full knowledge; then start my job.
Can anybody help me to get real time EEG signals for processing with speech applications? I need an EEG data set for normal and dumb persons.
Kindly send me stuff on,

Acoustic-phonetic production experiments often report relative segment durations (rather than absolute durations), mostly because relative durations are less prone to influences from speaking rate.
Typical reference units for normalization in the literature are:
1) units that contain the target segment (e.g., the syllable, the word, the phrase)
2) units that are adjacent to the target segment (e.g., sounds or words to the right or left)
3) the average phone duration in the respective phrase
Depending on the structure of the utterance and/or the nature of the target segment (e.g., phonemically long vs. short), differences across experimental conditions may appear larger or smaller (depending on whether the duration of the reference unit is negatively or positively correlated with the duration of the target).
Are there theoretical considerations that speak for (or against) one of those units of reference? Or do we need perception data in order to decide which relative measure participants are sensitive to? Should we always collect recordings in different speech rates in order to identify relative durations that are not (or least) influenced by the speaking rate manipulation?
Speech signal has both voiced and unvoiced portions, but focussing on transition occurs in the voicing portion alone, In the voicing regions the source is almost constant and transition occurs due to time varying nature of system that is source is time invariant & vocal tract system is time variant.
