開発者API

Addavoxローカライズをワークフローに統合しましょう。タイミング、品質保証、字幕、マジックリンクによるレビューエディターへのフルアクセスなど、ビデオの完全なローカライズを行うには、ビデオ吹き替えAPIを選択してください。また、書籍のナレーションや、書籍の翻訳とナレーションを一度に行うなど、その他のタスクには個別のサービス API を選択することもできます。

APIキー

APIキーはAddavoxアカウントに属します。上記の「ローカライズを開始」ボタンでアカウントを作成し、アプリでキーを生成してください。すべての通話料金はそのアカウントに請求されます。

個々のAPIサービスの料金は、お客様のクレジット残高から支払われます。クレジット残高は、 Addavoxアカウントでチャージおよび管理できます。ただし、フルビデオローカライズは例外で、プランと料金で選択したプランと同じ料金体系が適用されます。つまり、プランに含まれる通話時間分と、プラン料金で超過した通話時間分が課金されます。

同意と承認

すべてのAPIリクエストには、同意オブジェクトとトップレベルのモードフィールドを含める必要があります。これらを組み合わせることで、必要な権限と発言者の同意を得ていることを確認する、ジョブごとの証明レコードが作成されます。

モードフィールドは音声合成の種類を決定します。「voice_matched」は話者の声のクローンを使用し、「standard」は合成音声合成（TTS）を使用します。どちらのモードも価格は同じで、選択は完全にユーザーの同意に基づきます。

mode	string	最高レベル	`voice_matched` または `standard`
speaker_consent_obtained	boolean	音声一致のみ	特定可能な発言者からの明確な同意
content_rights_confirmed	boolean	両方のモード	コンテンツの所有権または有効なライセンス
eula_accepted	boolean	両方のモード	Addavox EULAに同意します
attested_by	string	両方のモード	責任者のメールアドレスまたは識別情報
attested_at	ISO 8601	両方のモード	リクエストから24時間以内

HTTP	コード	状態
403	CONSENT_MISSING	同意対象なし
403	CONSENT_INCOMPLETE	attested_by が欠落しているか、attested_at が無効です。
403	CONSENT_NOT_AFFIRMED	権利またはEULAは確認されていません
403	CONSENT_EXPIRED	24時間以上前に認証済み
403	SPEAKER_CONSENT_REQUIRED	話者の同意なしに音声が一致しました
400	INVALID_MODE	無効なモード値
