Real-time Audio in Meetings Using a Bot

Hello,

Welcome to Microsoft Q&A,

Step 1: Use Microsoft Graph API for Teams Call Integration

• Ensure your bot is correctly configured to capture media from Teams calls.

Step 2: Enable Real-Time Media Streaming

• Configure the bot to extract real-time media using the Teams Bot Framework.
• Reference: Real-Time Media Concepts

Example: Handling Audio Streams in a Bot

public

With this you will get the Audio stream of the team meeting, If you would like to convert this to text for transcription, You could use the Azure Speech service.

Step 3: Stream Audio to Azure Speech Service

• Route the extracted media stream to Azure Speech Service for transcription.
• Reference: Azure Speech-to-Text

Example: Sending Audio Stream to Speech-to-Text API

using

Step 4: Use Direct Line Speech for Enhanced Integration

• If required, consider using Direct Line Speech to improve communication between the bot and Azure Speech Service.
• Reference: Direct Line Speech Integration

Example: Enabling Direct Line Speech for a Bot

{
    "type": "directlinespeech",
    "serviceEndpoint": "https://directline.botframework.com/v3/directline"
}

As part of the next steps, to get your bot fully functional, deploy it using Azure Bot Service (Deploy a Teams Bot), ensure you grant the necessary Graph API permissions for calls and meetings (Graph API Permissions), and optimize audio processing for real-time transcription using Azure Speech Streaming API (Azure Speech Streaming API).
