はじめに
Open JTalk はバイナリでは配布されているのですが、自分のコードへ組み込むにはどうしたら良いかいまいち分かりませんでした。が、色々試してみてなんとか組み込めたので、その方法を紹介します。
ソースから Open JTalk をコンパイルしてみる
ダウンロード
まず、Open JTalk の本家のサイトを訪れ、Open JTalk のソースコードをダウンロードします。2012/04/14 現在では version 1.05 でした。
$ wget http://downloads.sourceforge.net/open-jtalk/open_jtalk-1.05.tar.gz
しかし、これだけではコンパイルできません。というのも、libopenjtalk [ja.nishimotz.com] によると、Open JTalk は HTS Engine API のサンプリアプリ的な位置づけのものらしいからです。ということで、HTS Engine API も同じくダウンロードします。こちらは version 1.06 でした。
$ wget http://downloads.sourceforge.net/hts-engine/hts_engine_API-1.06.tar.gz
コンパイル
まずは、HTS Engine API の方をコンパイルします。
$ cd hts_engine_API-1.06 $ ./configure $ make
これで bin と lib ができます。
次に Open JTalk の方をコンパイルします。
$ cd open_jtalk-1.05 $ ./configure \ --with-hts-engine-header-path=/home/hecomi/tmp/hts_engine_API-1.06/include \ --with-hts-engine-library-path=/home/hecomi/tmp/hts_engine_API-1.06/lib \ --with-charset=utf-8 $ make
（2012/04/15 utf-8 の設定を追加）
「/home/hecomi/tmp/」のとこは自分の環境に合わせて変えて下さい。
これで、bin/open_jtalk が出来ますので、Open JTalk で MMDAgent のメイちゃんに喋らせてみた - 凹みTips のように使えば喋ってくれます。
Open JTalk を組み込んでみる
どうやって組み込む？
と、コンパイルは出来たものの、じゃぁどうやって組み込むのさ？という話になると思います。そこで、open_jtalk の実行ファイルがどうやって出来たのか調べれば分かるんじゃね？となりまして、open_jtalk-1.05/bin/Makefile を覗いてみました。追ってみると、どうやら open_jtalk.c を次のようにコンパイルしている模様でした。
gcc open_jtalk.c \ -o open_jtalk \ -I ../text2mecab \ -I ../mecab/src \ -I ../mecab2njd \ -I ../njd \ -I ../njd_set_pronunciation \ -I ../njd_set_digit \ -I ../njd_set_accent_phrase \ -I ../njd_set_accent_type \ -I ../njd_set_unvoiced_vowel \ -I ../njd_set_long_vowel \ -I ../njd2jpcommon \ -I ../jpcommon \ -I /home/hecomi/tmp/hts_engine_API-1.06/include \ ../text2mecab/libtext2mecab.a \ ../mecab/src/libmecab.a \ ../mecab2njd/libmecab2njd.a \ ../njd/libnjd.a \ ../njd_set_pronunciation/libnjd_set_pronunciation.a \ ../njd_set_digit/libnjd_set_digit.a \ ../njd_set_accent_phrase/libnjd_set_accent_phrase.a \ ../njd_set_accent_type/libnjd_set_accent_type.a \ ../njd_set_unvoiced_vowel/libnjd_set_unvoiced_vowel.a \ ../njd_set_long_vowel/libnjd_set_long_vowel.a \ ../njd2jpcommon/libnjd2jpcommon.a \ ../jpcommon/libjpcommon.a \ /home/hecomi/tmp/hts_engine_API-1.06/lib/libHTSEngine.a -lstdc++
実際にこれを bin 内で実行してみるとコンパイルが通ります。なるほど、と言うことで open_jtalk.c をいじって自分仕立てにしたものをこんな感じでコンパイルすれば組み込めるわけです。
ディレクトリ構成
Open JTalk を使って喋らせることの出来るクラスを作って利用してみるサンプルを書いてみます。
次のようなディレクトリ構成にします。
work
├── Makefile
├── text_to_speech.hpp
├── text_to_speech.cpp
├── main.cpp
└── openjtalk/
├── hts_engine_API-1.06/
├── open_jtalk-1.05/
├── open_jtalk_dic_utf_8-1.05/ (追加）
├── mei_normal/ (追加）
└── hts_voice_nitech_jp_atr503_m001-1.04（mei_normal の代わりにこっちでもおｋ）Open JTalk 用の辞書を Open JTalk 本家サイト（Open JTalk）からダウンロードして配置しておきます。
ボイスについては本家サイトのもの（hts_voice_nitech_jp_atr503_m001-1.04）でも OK ですが、今回は Open JTalk で MMDAgent のメイちゃんに喋らせてみた - 凹みTips で使用したメイちゃんの声（mei_normal）でパラメタ調整しました。パラメタは引数として与えられるように修正しても良いと思います。
それぞれのコードは次のような感じになります。長いですが。

wav 再生部分はOpen JTalk で作った wav を OpenAL で再生する - 凹みTips を使ってます。コンパイル＆実行で「はろーわーるど！」と元気に喋ってくれます。
$ make $ ./tts ハローワールド！
あとは速度を変えたり、ボイスデータを変えたりするメンバを追加すれば、動的にピッチやボイスを変更可能になります。
おわりに
MMD Agent に含まれるメイちゃんのボイスデータは感情別になっているので、これを利用すれば感情を変化させるような表現もできるんじゃないでしょうか？
あと、wav 作らないでそのまま再生とか出来ないですかね？
