## DAF Pro Description
DAF Proは、吃音やパーキンソン病のある方が、ゆっくり流暢に話せるようサポートします。ヘッドホンをつけて話すと、自分の声がほんの一瞬遅れて聞こえます。

仕組み
遅延聴覚フィードバック（DAF）は、臨床的に認められた言語聴覚療法の手法です。自分の声が少し遅れて聞こえると、話す速さが自然にゆっくりになり、発話がなめらかで明瞭になることがあります。研究では、DAFは吃音のある方の約3人に1人に役立つとされ、パーキンソン病のある方が話す速さをコントロールするためにも使われています。

対象
* 吃音のある方
* パーキンソン病のある方
* 構音障害のある方
* クラタリング（早口言語症）のある方
* 言語聴覚士（臨床セッションや自宅練習に）

機能
* 遅延時間とピッチシフトを調整可能
* 処理遅延が小さく、短い遅延設定もそのまま保たれる
* バックグラウンドや画面オフでも動作
* 自分の発話を録音・再生
* 有線・Bluetoothヘッドセットに対応。Bluetoothはヘッドセットによって遅延が加わるため、短い遅延には有線ヘッドホンが適しています。

はじめ方
ヘッドホンをつけ、遅延を約50〜100msに設定し、「開始」を押して話します。話し方がゆっくり安定したと感じるまで調整してください。

英国の言語聴覚士が開発。買い切り：サブスクなし、広告なし、アカウント登録不要。
