You'll need a workaround.
How to Use the iPhone Text-to-Speech Feature
Open your iMail app on your iPhone. Depending on your settings and the number of email accounts you have forwarded to your phone, you may see the Mailboxes page or you could be taken directly to your email Inbox. The Mailboxes page lists the email accounts configured on your phone and has a number of unread messages noted in grey next to the arrow to open that Inbox.
When you open the Inbox, you see unread messages marked with a blue dot on the left next to the Sender's Name.

If there is no blue dot, that means the message has been read. To mark the message unread, hold the arrow at the right that would be to open the message and read it. Start to swipe the message to the left and you will see a gray, orange and red box appear. If you swipe too far, you erase the message and will need to retrieve it from the Trash folder.
The gray box says More. Select this box. A menu appears. Look for the option Mark. Select this and a new menu appears; select Mark as Unread.
Or maybe you just don't like the idea of strangers being able to preview your text messages when they pop up on your iPhone. Whatever the reason you want to hide text, WhatsApp, Instagram, Facebook, and other notifications, it only takes a few seconds to do it.
And if you want to hide specific text message chains or the texts from a specific sender, that's easy enough, too. If you don't want messages popping up on your iPhone screen, you can shut the notifications down wholesale or on a case-by-case app-by-app, e. Scroll down to and tap "Notifications. Open your Notifications settings page.
To stop all notifications, tap "Show Previews" at the top of the screen, then select "Never. To stop notification alerts from specific apps, like your text messages, scroll down on the notifications page and find the app in question, then tap it. Toggle "Allow Notifications" off to stop all of the app's displays from popping up, or unselect the options you'd like just below "Lock Screen" e. You can tap on an app to change its specific notification settings. If you turn off all notifications, you will have to specifically open each app to read any messages sent to you, or you will have to open specific apps where you have restricted display options.
You can also only allow notifications to go to your Notification Center, which you can access swiping down from the top of the screen. In this case, alerts won't show unless you go into the Notification Center.
If you don't want to hide all of your notifications but you do want to hide specific text chains, or stop a specific sender's messages from getting through to where they can be seen, there are two different approaches. Open the message s you don't want displaying as the chain continues. Tap near the top of the screen, by the icon of a face or the person's picture.
Select this box. A menu appears. Look for the option Mark. Select this and a new menu appears; select Mark as Unread.
You will be taken back to the Inbox and a blue dot should now be in front of the message. Because "iPhone mark unread" is not an option for text messages, you will need to work around by either forwarding the text to yourself or making a note to review it in your Calendar. None of these options are ideal and hopefully, future platforms beyond iOS 12 will rectify this problem.
2. Disable Lock Screen Message Notification
To forward the text means you are forwarding it to yourself. Open the text message you want to denote for follow up. Press on the message itself, the portion in the bubble in the line of messages. Hold your finger there until you see a menu pop up giving you the option of Copy or More. Tap More to get to the Forward option. When you forward, a new text box opens. Type in your own phone number so it will be sent to you.
