「羊が1匹、羊が2匹・・・」 羊数え歌(ひつじかぞえうた)とは、みなさんもよくご存知の歌であり、世界一長い歌詞のギネス記録を持つ民謡です。このアプリは、その羊数え歌をやさしい声であなたを安眠へと導くように歌ってくれます。 眠りたいのに眠れない方のために作りました。私が眠れなかった頃に作ったのですが、開発テストの最中によく眠気が誘われてウトウトしてしまうほどの威力抜群です。効果音程度にボーっと聞いていると音声が単調なので睡眠へと誘われます。よかったら使ってみてください。 あと子守唄としても使えるようです(実際に使っている方がいるようです)。 このアプリはiOS標準のTTS(TextToSpeach/音声読み上げ機能、VoiceOver。いわゆるSiriの音声。)に対応した為、読み上げる文言を自由に設定することが可能になりました。また日本語以外のその他の言語(英語やフランス語など)に対応していますので、「羊が1匹、・・・」も「1sheep、・・・」も可能です。数だけを数えることもできますので、子供とお風呂で100まで数えたり数の勉強などにも使えます。 〔読み上げる文言の例〕 ・羊が1匹、羊が2匹、羊が3匹・・・ ・1sheep、2sheep、3sheep・・・(英語) ・1moutons、2moutons、3moutons・・・(フランス語) ・子犬が1匹、子犬が2匹、子犬が3匹・・・ ・執事が1人、執事が2人、執事が3人・・・ ・1、2、3、4・・・(数のみ) ・1秒、2秒、3秒・・・(数と単位のみ) * ひたすら数を数え続ける機能しかありません。綺麗なグラフィック等はありません。 * バックグラウンドでの再生に対応しています。インターネットやSNSを見ている裏側で数えることができます。 * 必要なら端末の設定機能にて利用する声を追加できます。 (iOSの場合:[設定]―[アクセシビリティ]―[VoiceOver]―[スピーチ]―[声])
