# 下载: 示例训练语料text、lexicon 和 am建模单元units.txt
wget https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/requirements/lm.tar.gz
# 如果是匹配8k的am模型,使用 https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/requirements/lm_8358.tar.gz
tar -zxvf lm.tar.gz
# make sure that srilm is installed
# the format of the text should be:
# BAC009S0002W0122 而 对 楼市 成交 抑制 作用 最 大 的 限 购
# BAC009S0002W0123 也 成为 地方 政府 的 眼中 钉

编译TLG需要依赖fst的环境,请参考文档安装fts相关环境(点击此处)
# Compile the lexicon and token FSTs
fst/compile_dict_token.sh lm lm/tmp lm/lang
# Compile the language-model FST and the final decoding graph TLG.fst
fst/make_decode_graph.sh lm lm/lang || exit 1;
# Collect resource files required for decoding
fst/collect_resource_file.sh lm lm/resource
#编译后的模型资源位于 lm/resource
