Problem with keyboard on iPhone 8

A few months ago, I started to have an intermittent problem with the keyboard on my iPhone. For no apparent reason, it will appear differently. My normal keyboard has bold lettering and the microphone which I often use for dictation. Now there is narrow lettering and no microphone. Also, my access to the Hebrew keyboard disappears. There are other differences. Here is a screen grab of what it looks like. Any suggestions?
