1)我们还没有在mac上测试过decoder的编译,在mac上使用,你可以试用下docker镜像paddlepaddle/models:deep-speech-2,其中所有的依赖已经安装好,稍后会更新在README中; 2)decoder是兼容中文的,注意ctc_beam_search_decoder.cpp的第37-43行,如果vocabulary中没有空格,space_id就会被赋值为一个无效的index (-2)。 Thanks!
所以说 LSTM + CTC 是编码器 + 解码器，不能算错，但没什么意思。2.变长序列的端到端学习方法，...
问题一. ctc和encoder-decoder是两种不同的框架，但他们也有联系的，就是ctc框架下的lstm部分和encoder的...

CTC-loss是一种有效应对方法，通过在编码阶段单独对空白字符进行编码。CTC-loss的核心操作是插入空白字符，要求在编码过程中进行单独处理。假设文本序列为$l$，神经网络输出序列为$\pi$，计算$\alpha$表示去除重复和空白字符后的序列。此操作解决了不同长度序列的比较问题。为优化神经网络，定义反函数$\pi...

CTC compressor can be an effective approach to integrate audio encoders to decoder-only models, which has gained growing interest for different speech applications. In this work, we propose a novel CTC compressor based joint speech and text training (CJST) framework for decoder-only ASR. CJST ma...
