Description:

pyopenjtalkdict 0.3.4.dev2

pyopenjtalk

A python wrapper for OpenJTalk.
The package consists of two core components:

Text processing frontend based on OpenJTalk
Speech synthesis backend using HTSEngine

Notice

The package is built with the modified version of OpenJTalk. The modified version provides the same functionality with some improvements (e.g., cmake support) but is technically different from the one from HTS working group.
The package also uses the modified version of hts_engine_API. The same applies as above.

Before using the pyopenjtalk package, please have a look at the LICENSE for the two software.
Build requirements
The python package relies on cython to make python bindings for open_jtalk and hts_engine_API. You must need the following tools to build and install pyopenjtalk:

C/C++ compilers (to build C/C++ extentions)
cmake
cython

Supported platforms

Linux
Mac OSX
Windows (MSVC) (see this PR)

Installation
pip install pyopenjtalk

Development
To build the package locally, you will need to make sure to clone open_jtalk and hts_engine_API.
git submodule update --recursive --init

and then run
pip install -e .

Quick demo
Please check the notebook version here (nbviewer).

Create/Apply user dictionary

Create a CSV file (e.g. user.csv) and write custom words like below:

ＧＮＵ,,,1,名詞,一般,*,*,*,*,ＧＮＵ,グヌー,グヌー,2/3,*

Call mecab_dict_index to compile the CSV file.

In [1]: import pyopenjtalk

In [2]: pyopenjtalk.mecab_dict_index("user.csv", "user.dic")
reading user.csv ... 1
emitting double-array: 100% |###########################################|

done!

Call update_global_jtalk_with_user_dict to apply the user dictionary.

About run_marine option
After v0.3.0, the run_marine option has been available for estimating the Japanese accent with the DNN-based method (see marine). If you want to use the feature, please install pyopenjtalk as below;
pip install pyopenjtalk[marine]

And then, you can use the option as the following examples;
In [1]: import pyopenjtalk

In [2]: x, sr = pyopenjtalk.tts("おめでとうございます", run_marine=True) # for TTS

In [3]: label = pyopenjtalk.extract_fullcontext("こんにちは", run_marine=True) # for text processing frontend only
