PotatoHotDog は、Speaker.bot や他のサードパーティ製ミドルウェアを必要とせず、Streamer.bot から直接呼び出せる無料の TTS（Text-to-Speech）API を提供します。このガイドでは、音声を生成し、音声ファイルをダウンロードして自動的に再生する、Streamer.bot の Execute Code サブアクションに、小さなカスタム C# スクリプトを追加する方法を説明します。
コピペですぐ使える2つの用意済みスクリプトを用意しています。1つは静的な Piper TTS の声を再生するスクリプト、もう1つは自分のクローン声を再生するスクリプトです。どちらのスクリプトも、PotatoHotDog APIキー、ボイスID、そして話してほしいテキストだけが必要です。
前提となる引数
テキストを音声合成（TTS）するには、Execute Code サブアクションが実行される前に、Streamer.bot で3つの引数を指定する必要があります。つまり、以下の3つを指定する必要があります：
- APIキー。
- 生成したい声のIDです。静的な声またはクローン声のどちらかを指定します。
- テキスト。
これらは以下の Streamer.bot の引数に対応します。
- potatoKey
- potatoVoiceID
- potatoText
アクション内で引数を指定するには、Sub Actions を右クリックして、Add、Core、Arguments を順に選択し、最後に Set Argument を選択します。
Streamer.bot で Execute Code アクションを追加する
Streamer.bot を開き、Actions タブに移動します。新しいアクションを作成するか、既存のものを開いて、後で自分が認識できる名前を付けてください。例としては「PotatoHotDog TTS」のような名前です。
アクションを選択した状態で、サブアクションの下にある Add をクリックし、次に Core を選択してから Execute C# Code を選びます。これにより、Streamer.bot がその場でコンパイルして実行する生の C# コードを貼り付けられるサブアクションが追加されます。
以下のスクリプトのいずれかをコードエディタに貼り付けてください。静的な声を再生したい場合とクローン声を再生したい場合で、使うスクリプトが異なります。どちらのスクリプトも、アクション内にすでにいくつかの引数が存在することを前提としています。これらを設定する方法については、下記の前提引数を参照してください。
スクリプトを貼り付けた後は、Find Refs と Compile をクリックして、スクリプトが正しくコンパイルされていることを確認してください。
PotatoHotDog の API キーはダッシュボードから生成できます。アクションを保存してから、手動で実行するか、コマンドやチャンネルポイント報酬に紐づけて、音声が正しく再生されるかをテストしてください。
静的な声を再生するスクリプト
このスクリプトは固定の Piper TTS ボイスを再生します。音声を生成し、処理が完了するまで待機し、生成された音声ファイルをダウンロードして Streamer.bot で再生します。利用可能な固定ボイスIDの一覧は Static Voices ページで確認できます。

トラブルシューティング
スクリプトが期待通りに動作しない場合、トラブルシューティングの最善の方法はアクションログを確認することです。
アクション履歴からアクション変数を確認することで、これを実行できます。
