 In TalkBack, **Text-to-speech** opens Android's system speech settings. Backtalk has its own **Text-to-speech** screen, under **Feedback** in Backtalk settings. On this screen, you can choose a speech engine for Backtalk that's separate from Android's default engine, and set the speech volume, rate, and pitch with sliders. It also links to Android's system settings, and holds the speech settings that are described in the following sections.
 
+### Speech engine reading control
+
+The **Speech engine** reading control switches between your installed speech engines when you swipe up or down. It changes the engine of **Backtalk default**, so it's unavailable while a voice profile is in use. It isn't in the reading controls by default. To add it, go to **Reading controls**.
+
 ### Voice profiles
 
 A voice profile is a set of speech settings that you can switch to at once: a speech engine, language, voice, volume, rate, pitch, and **Send long text a sentence at a time**. For example, one profile can use a slower rate for long text while **Backtalk default** stays fast. To add one, go to **Text-to-speech** > **Voice profiles** and choose **Add voice profile**. When you choose a language, the voice list shows only the engine's voices in that language.
 
-To switch profiles, swipe up or down with the **Voice profile** reading control, or choose **Voice profile in use** on the **Voice profiles** screen. The **Voice profile** reading control replaces the **Speech engine** reading control. It isn't in the reading controls by default. To add it, go to **Reading controls**. You can also add a **Voice profile** item to the Backtalk menu in **Backtalk menu** settings, which lists the profiles and says which is in use. The **Choose voice profile**, **Previous voice profile** and **Next voice profile** actions can be assigned to gestures and keyboard shortcuts.

 The reading control goes through the profiles in the order of the **Voice profiles** screen, after **Backtalk default**. To change the order, hold a profile and drag it, or use the **Move up** and **Move down** actions. Backtalk says which profile it moved above or below. Profiles also have **Rename** and **Delete** actions, which a long press shows too.
