Webobtained by weight quantization and phone synchronous decoding [5]. Following Hwang et al. [10] and Zhuang et al. [23], key words are searched on the phone lattice generated by the CTC model. The confidence score for each key word is determined by the posteriors output by the ASR model and the minimum edit distance with the key word phone string. WebSep 30, 2024 · A novel phone synchronous decoding framework is proposed by removing tremendous search redundancy due to blank frames, which results in significant search speed up and efficient and effective modular speech recognition approaches, second pass rescoring for large vocabulary continuous speech recognition (LVCSR), and phone-based …
WebAn automatic speech recognition system searches for the word transcription with the highest overall score for a given acoustic observation sequence. This overall score is typically a weighted combination of a language model score and an acoustic model score. We propose including a third score, which measures the similarity of the word …
