対話型IVRの設定方法

この記事では、受信音声サービスの対話型IVRを設定する方法について説明します。 Bright Patternの対話型IVRはボットのフロントエンドであるため、ほとんどの設定は、Bright Pattern外、即ちボット側で（つまり、ワークスペースのGoogle、GoVivace、またはIBMを介して）行われます。この手順は、サービスプロバイダーを通じてSTTおよびTTSエンジンを設定した後のステップについて説明します。

For more information, see the Contact Center Administrator Guide, section What Is Conversational IVR?

Prerequisites

If you have not already done so, please complete these steps before proceeding:

• Create a Watson Assistant, Alterra Answer Bot, or Amazon Lex bot

• Add a bot/chat suggestions engine integration account

• Download and import our conversational IVR scenario template: File:App Conversational IVR Example.zip

Procedure

Step 1: Set up a Speech-to-Text engine through your service provider

• If using IBM Watson: In IBM Cloud, add Speech-to-Text as a service.

• If using Google: Enable Google Cloud Speech API.

• If using GoVivace: Enable Speech to Text API.

Step 2: Add Speech To Text Integration Account

A Speech To Text integration account uses your credentials to connect Bright Pattern Contact Center to a third-party STT engine. Integration accounts are configured in the Contact Center Administrator application.

1. In Contact Center Administrator > Call Center Configuration > Integration Accounts, add a new Speech to Text integration account. For property descriptions, see the Contact Center Administrator Guide, section Speech To Text Integration (STT).
   
   
2. Note that if you do not see Speech to Text as an option when adding a new integration account, that option has not been enabled for your contact center. See your service provider for more information.

Step 3: Set up a Text-to-Speech engine through your service provider

• If using IBM Watson: In IBM Cloud, add Speech-to-Text as a service.

• If using Google: Enable Google Cloud Speech API.

Step 4: Add Text To Speech Integration Account

Likewise, a Text to Speech integration account uses your credentials to connect Bright Pattern Contact Center to a third-party TTS engine. TTS integration lets you create voice prompts in numerous supported languages to automate bot responses.

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
   
   
   
2. See the Load Voices property. If this is a Google TTS integration account, load voices by completing an additional step in Google. See How to Load Voices from Google Cloud Text-to-Speech API.

3. Then click Load Voices. This may take a few minutes. When the voices are loaded, a message will display the date they were added: “Loaded on XX/XX/XX.”
   
   
4. Click Apply to save your changes.

Step 5: Add a Voice Scenario That Includes Play-Listen and Bot Scenario Blocks

The Play-Listen scenario block is a key part of conversational IVR. This block uses the integrated TTS and STT accounts that you just set up to play voice prompts to the caller and to listen for the caller’s response.

Chat Bot Select Account and Ask a Bot blocks allow you to choose which integrated bots will be used for interacting with callers.

1. In Contact Center Administrator, go to Scenarios > Voice and import our conversational IVR scenario template: File:App Conversational IVR Example.zip.
   
   
2. Work through our scenario-building exercise, How to Use Conversational IVR in a Scenario.
   
   
3. Modify the scenario to suit your needs, being sure to select the correct bot and STT account in the scenario blocks.

Step 6: Add or Select a Scenario Entry

The scenario entry is the entry point for the caller. For more information, see the Contact Center Administrator Guide, section Scenario Entries Overview.

1. Go to Scenario Entries > Dial-in and add a new scenario entry.
   
   
2. At the most basic level, add Name, Scenario, Service, Internal numbers, External numbers, and Transcribe calls (if no STT account is configured, this will be greyed out).
   
   
3. Click Apply.
   
   

You're Done

This completes your conversational IVR configuration. Next, you should try it out by calling your contact center's access number and interacting with the IVR and bot. You can always come back to your scenario and entry point for further editing.
