The issue just started happening 5 days ago. I've already reset all Edge settings and still same issue. I run speed tests and they show my internet is running fine.

Microsoft Edge is up to date.

Version 150.0.4078.83 (Official build) (64-bit)

This started happening to me too. Glad to know it's not just my system. Seems like it's losing its connection to the API that Read Aloud is using or something. Annoying and shouldn't have happened, but I suspect it will get patched up. Read Aloud is used a ton by a few, but not by most so it's probably not top of mind. I would recommend going to Help & Feedback -> Send Feedback in Edge and reporting the issue there as well if you haven't already.

Hello,

Please create a new profile in Microsoft Edge and test whether the Read Aloud feature works correctly there.

In the Edge address bar, enter:

edge://settings/profiles

and press Enter.

Click “Add profile” and test Read Aloud in the new profile.

If the issue does not occur in the new profile, the cause is a corrupted Edge profile, which cannot be repaired by resetting Edge. In that case, please consider migrating to a new profile.

How to migrate your profile:

In the Edge address bar, enter:

edge://settings/profiles

If you are not signed in with your Microsoft account, please sign in.

Make sure all sync options are turned ON and wait until synchronization is fully completed.

Sign out of your Microsoft account from the old profile.
In the new profile, open:

edge://settings/profiles

Sign in with your Microsoft account again.

Turn all sync options ON and wait until synchronization is fully completed.

Your profile migration is now complete.

Favorites, extensions, and other data will be synchronized to the new profile.

Hi,

I've had this exact issue. Making a new profile got the voice options to work again! However, I believe I've discovered a possible source of the issue: the "turbo" voices. I tried to use them, and then that's when my voice options became "undefined" (aside from the local, built-in voices such as Zira, Mark and David). I tried to use the turbo voices on the new profile, and they did not load at all. For now, I'm assuming those options are broken and may even break read aloud function in my Edge profile.

Thank you.

To add, now the new profile has gone back to the problem in the initial post, and creating a new profile does not fix it anymore.

Thank you.

I have received your feedback.

It seems the issue is still ongoing.

I believe you have tried the steps I suggested earlier, but please let me know which ones you have completed and what the results were.

With that information, I can propose the next solution.

Your only option is to hope Microslop fixes it one day (they don't like fixing bugs in my experience so I wouldn't get your hopes up). You can already find numerous posts going back a few days about this so no hotfix for certain.

In the meantime you have 2 options:

Create a new profile and swap between them every time it breaks.
What I'm doing: Download the Microsoft Edge Beta and copy your %LOCALAPPDATA%\Microsoft\Edge\User Data\Default Folder to %LOCALAPPDATA%\Microsoft\Edge Beta\User Data\Default and swap between those to keep all your extensions, scripts, and settings synced. I think you can do this with Profile's to but meh already had Beta downloaded and no it doesn't fix it.
Hidden 3 option: Find a better TTS solution so you can uninstall Edge and please share it with us.
