Google Cloud 音声合成 APIの音声読み上げ方法

Google 音声合成統合アカウントはGoogle Cloud API 認証情報を使い、Bright PatternコンタクトセンターをGoogleのTTS エンジンに接続します。 統合を設定すると、サポートされている多数の言語で音声プロンプトを作成して、ボットの応答を自動化できます。

このような統合アカウントを設定するには、アクセス用の認証情報を提供するだけでなく、Google側で特定の言語の音声を承認する必要もあります。

この記事では、上記を行う方法と、Google 音声合成統合アカウントで音声読み上げ方法について説明します。

Procedure

Step 1: Go to Integration Account Properties in Contact Center Administrator

1. In Contact Center Administrator > Call Center Configuration > Integration Accounts, add a new Text to Speech integration account. For property descriptions, see the Contact Center Administrator Guide, section Text To Speech Integration (TTS).
   
   

   

   Select the type of TTS integration account
