Phone synchronous decoding with ctc lattice
WebConnectionist Temporal Classification (CTC) has recently shown improved efficiency in … WebPhone Synchronous Decoding with Blank Skipping PSD algorithm is first used in [24] to speed up the decod-ing and reduce the memory usage with CTC lattice. A CTC model’s peaky posterior property allows the PSD algorithm to ignore blank prediction frames and compress the search space. We found the same peaky posterior property also exists
