In any Automatic speech recognition system, the first step is to extract the features. In other words, we need to extract the identifiable components of the audio signal and throw away other messy information, such as background noise, mood, etc. Understanding how speech is produced is very helpful for us to understand speech. People pro ...

The last issue discussed it as a whole Unidirectional linked list . On this basis, two points are added, one-way circular linked list and two-way circular linked list. It can be seen from the literal that the linked list forms a ring structure. The difference is whether the ring can only cycle in one direction or two directions. One way circu ...
