実行方法
スマートフォンでアプリを立ち上げて、トリガーとなるタグと追加したカスタムタグをつなげてください。
その後、下記の画像のようにtextの部分にしゃべらせたい言葉を入力し、addressの部分にRaspberry Pi側で実行中のサービスでxxxxxxxと表示されている部分を入力してください。
curl -X POST -d "text=Hello Google Home" https://xxxxxxx.ngrok.io/google-home-notifier
あとはトリガーが実行したら、Google Homeが入力されたテキストをしゃべります。
感想
レスポンスもよく3-5秒後に喋ってくれるので、ラピッドプロトタイピングで音声フィードバックを検証するのに便利だと思いました。個人的には、addressのxxxxxxの生成される乱英数字を固定したかったのですが、ngrokのサブドメイン固定が月額で有料だったので諦めました。笑
