Perl で漢字仮名混じり文から、VSQファイルを自動生成させてみました。形態素解析にはMecabを使用しています。Mecabは、自然文の読みまでを出力してくれるので、音声合成に楽に適用できます。
ここで、Mecab の設計者およびプログラマの方々に感謝いたします。
ミクに喋らせる文章は、特許法１条 「この法律は、発明の保護及び利用を図ることにより、発明を奨励し、もつて産業の発達に寄与することを目的とする。」 です。
「test_miku011.mp3」をダウンロード
「test_miku011.vsq」をダウンロード
今回は、アクセントっぽいのも入れてあります。あくまでテスト用の仮コーディングであり、標準語のアクセントではありません。
ソースコードはこちらです、UTF８の文字コードでセーブしてください。
