Spectral tilt for join cost

Description
Consider spectral tilt in join cost computation.
Compare MFCC- and formant-based join cost with the spectral tilt included:
- MFCC + spectral tilt
- formants + spectral tilt
- MFCC + formants + spectral tilt
I have just started experiment with:
- spectral tilt (static) + MFCC (classic)
- spectral tilt (static) + formants (SLOPE)
- spectral tilt (static) + formants (ABS)
- spectral tilt (static) + formants (ABS) + MFCC (classic)
where:
- MFCC (Eucl) is the "classic" MFCC distance computation using Euclidean distance between MFCC vectors (see MFCC-cost equation at wiki)
- spectral tilt (static) is the use of Euclidean distance of spectral tilt coefficients (computed at #4211), handled exactly as the MFCC coefficients
- formants (ABS) is the mean absolute difference of the formant contour (ABS), as described in wiki
- formants (SLOPE) is the absolute difference of formants and their slopes (SLOPE), as described in wiki
The data to synthesize are shorter phrases (5 words or 40 chars max), from which the difference logs will be collected and (as usual) the most differing phrases will be compared by listening tests.
If you have another suggestions, especially regarding the tests data, just write a note here ...
