English(EN) From 2.1M Hours of Raw Broadcast Audio to Finnish Speech SSL: Confidence Filtering and Architectural Analysis at Scale

新的芬兰语语音SSL方法使用ASR置信度过滤提高准确性

研究人员开发了一种通过基于自动语音识别(ASR)置信度过滤原始广播音频来进行芬兰语语音自监督学习(SSL)的新方法。该方法应用于210万小时的无约束广播数据,与传统的语言识别过滤相比,词错误率(WER)相对提高了3-7%,即使在较小的训练集下也是如此。研究还对Transformer、Macaron-Net、Conformer和E-Branchformer架构在匹配的参数预算下进行了比较分析,结果显示在芬兰语SSL基线之上有所改进,尤其是在Base规模和域外任务上。 AI

影响 这项研究可能带来更高效、更准确的语音处理模型,尤其是在低资源语言和嘈杂音频环境方面。
