Using Microsoft Azure Speech SDK and exporting in WebGL

Hello! I’m using Microsoft Azure Speech SDK in my Unity game (the player is controlled by you speaking into the microphone). I’m getting this error when I export the game via WebGL:

Assets/Scripts/GameSceneScripts/VoiceRecognition.cs(10,17): error CS0234: The type or namespace name 'CognitiveServices' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)

Am I missing something here? I’m bringing in the Speech SDK like this in the code:

using Microsoft.CognitiveServices.Speech; 

It’s compatible with other formats and I’m not getting this error but I need to fix this for WebGL specifically. Any help would be greatly appreciated!
