Describe the bug

Customer has added speech functionality to Bot. When they test the Bot with Web Chat, they do not see any issue. But when testing the Bot with Emulator (v4), the customer sees that the microphone icon gets disabled (greyed out) after sending the first message to the Bot, irrespective of whether the message is sent as text by typing or using Voice.

To Reproduce

1. The customer's Bot code's speech functionality works as expected with Web Chat.

2. The microphone icon is getting grayed out when testing the Bot on Emulator.

3. Even if the first message to the Bot is sent in text, the microphone icon is getting grayed out.

4. Created a new Bot, integrated Direct Line Speech channel to the Bot and tested the Bot on emulator. Even for this new Bot, we were seeing the microphone icon getting grayed out.

Expected behavior

N/A
