Sequence alignment is a big deal in genetics. Probably the same idea. You represent DNA sequences as a matrix and calculate the optimal path through it.

For text-speech conversion it'd be aligning sound waves with dictionaries and language rules.

so, the alignment matrix is the "feature matrix"
in speech case (text <-> spectrogram), the first column in matrix is an entry for the corresponding frame for the first sentence, the second is the corresponding entry for the second sentence,
the same for all sentence.
the idea is that you can use the first row (the feature vector) for the first sentence, the second row for the second sentence, and so on.
