IBM Cloud 音声合成 APIの音声読み上げ方法

IBM Cloud 音声合成統合アカウントはIBM Cloud API 認証情報を使い、Bright PatternコンタクトセンターをIBM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、 音声リスト化という APIメソッドを使って、IBMから利用可能な音声のリストを取得する必要があります。

This article describes how to do just that and load voices to your Watson Text to Speech integration account.

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.
   
   
2. Select Watson as the account type.
   
   

   

   Select the type of TTS integration account

   
   
   
3. The Text to Speech integration account properties will open.

4. Set the URL of your IBM Text to Speech service instance URL. You can find the URL in your Text to Speech service credentials. For example: https://api.us-south.text-to-speech.watson.cloud.ibm.com/instances/0123a4c0-5d67-8cec-9c10-a0cdbb1234b5
   
   
5. Set the API Key, which is found on IBM Cloud in your Text to Speech service credentials.
   
   
6. The Load Voices property is grayed out and you cannot click it until you proceed with Step 2.
   
   

Step 2: List Voices in IBM Cloud

This step uses IBM Cloud's List Voices and Get Voices API methods.

1. In your web browser, go to https://<your-ibm-tts-instance-url>/v1/voices. For example: https://api.us-south.text-to-speech.watson.cloud.ibm.com/instances/0123a4c0-5d67-8cec-9c10-a0cdbb1234b5/v1/voices
   
   
2. Authenticate with your IBM Text to Speech credentials:
   1. Username - apikey
      
      
   2. Password - The same Text to Speech API key as set in the integration account properties
      
      

      

      
      
      
3. A list of known models (voices) will be shown in JSON.
   
   
4. You may optionally select the URLs for the individual models and open them in your browser to get more information.
   
   

Step 3: Load Voices

1. Go back to the Contact Center Administrator application, to the Watson TTS integration account properties, and click Load Voices. This may take a few minutes. If the voices field still says "empty" after clicking Load Voices, wait a few more minutes and try again.
   
   
2. When the voices are loaded, a message will display the date they were added: “Loaded on XX/XX/XX.”

3. Click Apply to save your changes.< 前へ
