The Tile and Horizontal activities, Paragraph, 1in3, 1in4, 1in5, Million and Next word now have a new feature: TTS sections.
If you have enabled TTS for your resource, you should see TTS sections as one of the TTS options for these activities. If you select TTS sections, a "Speak" button appears with a dropdown box for each sentence in the text. (See above). Click "Speak" to hear the current section.
See the embedded Tile 3x4 activity below as an example:
Note also that the "no-onscreen-keyboard" versions of the "No letters" activities, which are available on some devices for both text and match activities, now have TTS enabled using the same "Speak" button.
