英語TTSでMineを「マイン」と読む誤読を修正する - #42
Conversation
英語 TTS が駅名・路線名の「Mine(みね)」を英単語 "mine" として 「まいん」と読むため、辞書語の連結 "Me-nay" に置換して /mi.neɪ/ に寄せる。 Keisei・Seibu と同様に単語境界で一致させ、別語の一部は置換しない。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Takamine や Minezaki のように英名の語中・語頭に含まれる mine も 置換対象にし、前後に英字が続く場合はハイフンで区切って Me-nay を独立させる。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

概要
英語 TTS が英名に「Mine」を含む駅名・路線名(みね)を、英単語の "mine" として「マイン」と読んでしまう問題を修正します。
変更内容
src/utils/normalize.ts:normalizeRomanTextに、英名に含まれるmine(大文字小文字は区別しない)をMe-nayに置き換える処理を追加しました。Kay-say、Seibu →Say-booと同じ方針で、置き換え先は辞書にある英単語の連結にしています。辞書にない綴りだと TTS エンジンが読みを推測することになり、エンジンごとに結果がぶれるためです。TakamineやMinezakiのように語中・語頭に含まれる mine も置き換えます。前後に英字が続く場合はハイフンで区切ってMe-nayを独立させ、語頭のときだけ先頭を大文字にします。src/utils/normalize.test.ts: 置き換える例、置き換えない例、2回続けて正規化しても結果が変わらないことを確認するケースを追加しました。変換例
