English(EN) PERL: Pinyin Enhanced Rephrasing Language Model for Chinese ASR N-best Error Correction

新型 PERL 模型通过音韵和语义融合增强中文 ASR 错误校正

作者 PulseAugur 编辑部 · [1 个来源] · 2026-07-17 04:00

研究人员开发了 PERL，一个旨在校正中文自动语音识别 (ASR) 系统中错误的新语言模型。PERL 通过采用受约束的改写流程来应对语音错误和长度限制的挑战。该模型融合了语义和语音（拼音）表示，并通过掩码预算强制执行目标长度，从而在 Aishell-1 和 DoAD 等基准测试中显著降低了字符错误率。 AI

影响提高了中文语音识别系统的准确性，可能有助于下游应用。

PERL：用于中文 ASR N-best 错误校正的拼音增强改写语言模型

arXiv:2412.03230v3 Announce Type: replace Abstract: Chinese ASR correction is challenging because errors are often \emph{phonetic} (many characters share similar Pinyin) while the correction model must also obey a \emph{length constraint} under noisy N-best hypotheses. Existing a…
