"""
This is an algorithm for building a sync map.
It synthesizes text and then aligns synthesized audio with the recorded audio
using a variation of the DTW (Dynamic Time Warping) algorithm.
The main features of this algorithm are:
1) It can handle structural differences in the beginning and in the end of files.
2) It finds an approximation to an optimal warping path in linear time and space using FastDTW approach.
Note that while the algorithm does not require one-to-one correspondance
between text and audio files (i.e. the splitting can be done differently),
the quality of the result is sensitive to the choice of skip_penalty and radius parameters,
so it is recommended to have such a correspondance.
Alignment details:
Synthesized and recorded audio are represented as sequences of MFCC frames.
These sequences are aligned using variation of the DTW algorithm.
In contrast to the classic DTW, this algorithms can be used
to align sequences with structural differences in the beginning or in the end.
Steps to build a sync map:
1) Synthesize text file and produce a list of anchors.
Each anchor represents the start of the corresponding text fragment in a synthesized audio.
2) Get sequences of MFCC frames of synthesized and recorded audio.
3) Get their warping path by calling the alignment algorithm.
4) Check whether the extra content is found, calculate mapping boundaries.
5) Map anchors inside the boundaries to the recorded MFCC sequence using warping path from step 3.
6) Start all over again considering:
If there is an extra content in the end of synthesized sequence, align it with the next audio file.
If there is an extra content in the end of recorded sequence, align it with the next text file.
If both sequences have extra content in the end, align text tail with the next audio file.
If none of the above, align next text and audio files.
