||The content can be read aloud
||Focus on the beginning of a paragraph or a sentence and initiate reading with text-to-speech using a feature of the reading system.
||In the menu, "text to speech" in experimental features should be enabled. Then there is a play button next to the bookmark icon in the top right of the page. The reading starts at the top of the currently displayed text.
||Stop and resume reading
||Initiate reading from any point in the book. Stop Read Aloud and note the last read position. Initiate reading again using the Read Aloud feature and check if reading starts at the last read location.
||The pause feature performs as expected. It resumes from the last spoken word. There are also controls to move the reading position back and forward, and to read from top.
||The Read Aloud feature should continue until interrupted by the user
||The Read Aloud feature should continue until interrupted by the user, keeping the text being spoken in view.
||The display scrolls to keep the text being read in view. The read aloud stops at the bottom of the current content.
||All text should be read in the proper order
||Sample text has been provided below to test the reading order. The Paragraph 2 should be read after Paragraph 1 by the Read Aloud feature. Note that visually Paragraph 2 is placed to the left of Paragraph 1 but it is second in the reading order.
||The text is read in the correct order.
||Change Read Aloud reading speed
||It should be possible to adjust (increase/decrease) the speed of reading.
||The "More text to speech controls" button is next to play. This provides for adjusting the read aloud speed and volume. The voice can be selected when enabling the feature. The user preference can be saved in Main menu / Text to speech
||Text to Speech handles punctuations and document structure appropriately
||When Read Aloud is activated, there should be slight pauses after headings, list items etc., rather than reading as if it is one continuous section of text.
||The text is read aloud as expected.
||Text is emphasised as it is spoken by read aloud
||Check if the Text is emphasised as it is spoken by read aloud.
||The paragraph being spoken is highlighted with a differentiated background. A black underline emphasizes the currently spoken word. The underline is not visible in night mode.
||The emphasis or highlight colour can be changed
||Activate Read Aloud feature as described in the previous test. Change the colour of emphasis or visual highlight of the text being read aloud using any feature available in the reading system or the operating system. The users should have a choice of different colours for text highlighting.
||The visual highlighting cannot be customized or turned off.
