同时,还为方言和细分领域的语音识别任务打开了大门,这些模型以前需要更多的音频数据才能达到可接受的性能。第二,作者还开发了一种跨语言方法,称为XLSR,可以学习几种语言通用的语音单元。当只有少量未标记的语音样本时,此方法会有所收益。 像BERT一样,wav2vec是通过预测语音被掩盖部分(masked parts)的语音单元来完成...

The output size of this layer corresponds to the number of tokens in the vocabulary, which doesnotdepend on XLS-R's pretraining task, but only on the labeled dataset used for fine-tuning. So in the first step, we will take a look at the chosen dataset of Common...
改进3:作者在生成器中的CNN前还加入了一层batch norm和线性映射,以代替预处理步骤中的PCA降维操作。作者也提到为了模型的正常收敛,当我们使用wav2vec 2.0 Large/XLSR-53作为语音特征提取器时,需要将batch norm的scaling factor初始化为30/35。 改进4:为了进一步提升模型的性能,作者还引入了类似于HuBERT第一阶段训练...
在这个视频中，FAIR重点介绍了实验室在无监督、自监督技术上的关键成就，包括wav2letter、无监督机器翻译、wav2vec、Librilight、wav2vec 2.0、XLSR、wav2vec 2.0 +自我训练。“我们希望这将为世界上更多的语言和方言带来高效的语音识别技术。我们会发布代码，让社区的人也能以仅使用未标记的语音录音和未标记的...
