We now have three ways for computation of the
MEL band analysis.
In Section 5.2.3, we discussed the SPA-based
implementation of MEL bank analysis,
which is implemented by module
software/module_mel_bank.m with method='spa'.
In Section 5.2.6, we developed the CLT-based
approach, which is the
software/module_mel_bank.m with method='clt'.
These two modules compute the feature
The ML method is implemented by software/module_mel_ml.m.
The ML approach finds different features,
Therefore, head-to-head comparison of the J-function is not meaningful.
We will revisit this question later in Chapter 10.
