在呼叫建立期间未设置认知服务配置时不允许请求

Question

在解决了这个问题中的错误之后，我遇到了另一个错误，如下所示：

Request not allowed when Cognitive Service Configuration not set during call setup.

我正在尝试使用 Azure 通信服务和语音资源构建一个简单的 IVR。我按照将 Azure 通信服务与 Azure AI 服务连接中的说明手动将 Azure 通信服务与认知服务连接起来，但如何在呼叫设置中配置认知服务？有没有内置函数可以在通话过程中设置这样的配置？

这里，您需要正确配置与语音服务提供商的azure通信服务，如下所示。

• 前往语音服务

将此“认知服务用户”角色分配给您的语音服务。检查此SO链接以获取更多理解

• 使用应用程序中的凭据和端点将语音服务集成到呼叫设置中。

// Define Cognitive Services configuration
const cognitiveServicesConfig = {
  subscriptionKey: "your-cognitive-services-subscription-key",
  endpoint: "your-cognitive-services-endpoint-url"
};

app.get('/', async (req, res) => {
  try {
    if (eventType === 'Microsoft.Communication.CallConnected') {
      const callConnectionId = eventData.callConnectionId;
      console.log(`Call connected with callConnectionId: ${callConnectionId}`);

      // Play an initial audio
      const initialPlaySource = { url: "...", kind: "fileSource" };
      console.log('Playing initial audio to all participants...');
      await callAutomationClient.getCallConnection(callConnectionId).getCallMedia().playToAll([initialPlaySource]);
      console.log('Initial audio played.');

      // Define another audio source for the speech recognition prompt
      const promptPlaySource = { url: "...", kind: "fileSource" };
      console.log('Defined prompt audio source for speech recognition.');

      // Define the target participant for the recognition (if needed, modify accordingly)
      const targetParticipant = { identifier: { communicationUser: { id: "participant-id" } } };
      console.log(`Target participant for recognition: ${targetParticipant.identifier.communicationUser.id}`);

      // Configure the speech recognition options with Cognitive Services
      const recognizeOptions = {
        playPrompt: promptPlaySource,
        initialSilenceTimeoutInSeconds: 10,
        interruptPrompt: true,
        operationContext: "OpenQuestionSpeech",
        kind: "callMediaRecognizeSpeechOptions",
        cognitiveServicesConfig: cognitiveServicesConfig // Add the Cognitive Services configuration here
      };
      console.log('Configured speech recognition options.');

      // Start the speech recognition process
      console.log('Starting speech recognition...');

• cognitiveServicesConfig

  对象是使用认知服务/语音服务资源的订阅密钥和端点 URL 创建的。

通过上述配置，您可以访问将语音服务与通信服务/呼叫设置连接。
