| Beschreibung: | A capacity to recognize speech offline eliminates privacy concerns and the need for an internet connection. Despite efforts to reduce the memory demands of speech recognition systems, these demands remain formidable and thus popular tools such as Kaldi run best via cloud computing. The key bottleneck arises form the fact that a bedrock of such tools, the Viterbi algorithm, requires memory that grows linearly with utterance length even when contained via beam search. A recent recasting of the Viterbi algorithm, SIEVE, eliminates the path length factor from space complexity, but with a significant practical runtime overhead. In this paper, we develop a variant of SIEVE that lessens this runtime overhead via beam search, retains the decoding quality of standard beam search, and waives its linearly growing memory bottleneck. This space-complexity reduction is orthogonal to decoding quality and complementary to memory savings in model representation and training. |
