簡単な回答
Microsoft Teams会議を文字起こしするには？
AskSiaでMicrosoft Teams会議を文字起こしするには、Teamsブラウザタブから音声をキャプチャしてライブ文字起こしするか、後でMP4またはM4A録画をアップロードします。AskSiaは最大10人の話者を自動的に識別し、タイムスタンプを適用し、40以上の言語での同時翻訳をサポートします。Teams管理者のインストール、カレンダーの権限、Microsoft 365の文字起こしライセンスは不要で、組み込みのTeams文字起こしが無効になっているテナントや、クロステナント会議に便利です。無料プランでは、無制限のライブTeams文字起こしと最大30分の録画が含まれます。

AskSiaを選ぶ理由
AskSiaがMicrosoft Teams文字起こしに強力なツールである理由。
ほとんどのサードパーティ製Teams文字起こしツールは、管理者によるインストール、Microsoft 365の文字起こしライセンス、または会議への別のボットの追加を必要とします。AskSiaはブラウザタブから直接音声をキャプチャするため、すでに参加できるどのTeams会議でも機能します。
リアルタイム文字起こし、遅延なし
ライブTeams文字起こしは100ミリ秒未満の遅延で更新されます。話者が話すにつれて画面に単語が表示されるため、長い会議、多言語通話、複数の参加者との議論を追うのに役立ちます。
100ミリ秒未満の遅延
通話全体の話者ラベル
AskSiaは、1つのTeams会議で最大10人の異なる話者を識別し、その発言を色分けします。通話後に「PM」、「エンジニア」、「ステークホルダー」のように名前を変更すると、その変更はトランスクリプト全体に適用されます。
最大10人の話者、名前変更可能
40以上の言語、翻訳付き
AskSiaは会議のソース言語を自動検出でき、同時にトランスクリプトを翻訳できます。国際的なスタンドアップ会議、多言語クラス、一部の参加者が母国語で読みたい会議に便利です。
