Highlight Function For Disabled Speakers Tied To Voicechat

I have a friend who doesn't have the ability to speak however she actively likes to participate in voice chats and communicates through other channels tied to the voice chat such as #mutechat. However, her text responses are typically drowned out because the people in voice chat forget to check the mute channels and carry on their vocal conversations.

Is there some function or even a role that can be implemented that would allow those who cannot speak but want to participate in voice chats have text or alerts that stand out during the conversations so they aren't left feeling ignored or forgotten?
