**TLDR:** A core learning and decoding approach that helps recover text from speech sequences with unknown alignments.

<p>CTC is an important framework that enables learning when explicit alignments between speech and text are unavailable. It is especially useful when it is unknown which character corresponds to each acoustic frame. It produces output sequences through a blank symbol and collapsing repeated predictions. Although more advanced architectures exist today, CTC remains both a theoretical and practical cornerstone of ASR.</p>
