This is a ChiNese Text Normalization (CNTN) tool for Text-to-speech system, which is based on sparrowhawk. The main purpose of this project is to provide some grammar files for Chinese TN, rather than modify the source code of sparrowhawk or show how to integrade it to a TTS system.
WIP Note: Work In Progress
You could follow the steps in file install_sparrowhawk.md to install sparrowhawk. In addition, for a quick startup, we also provide pre-built binaries under the sparrowhawk directory and required libraries. However, if these binaries could run properly in you PC, that may be caused by your system environment, you should built it manually.
First, prepare enviroment:
cd sparrowhawk/bin
. bin/path.sh
English:
cd grammars/en/en_toy/classify
thraxmakedep tokenize_and_classify.grm
make
cd ../verbalize/
thraxmakedep verbalize.grm
make
cd grammars/en/
normalizer_main \
--config=sparrowhawk_configuration.ascii_proto \
--multi_line_text \
< test.txt \
2>/dev/nullNote: The --path_prefix can not be applied to the sentence_boundary_exceptions.txt file. This may be a bug. That's why we should cd into the grammar dir rathar use the --path_prefix flag.
If you want to debug the grammars, the thraxrewrite-tester command is recommended, for example:
thraxrewrite-tester --far=en_toy/classify/word.far --rules=WORD
