My Talking Books lets you jump by time through a book. While the audio is playing, pause the narration and then use a command like the following examples:
“Jump forward 2 hours and 30 minutes.” The audio stream will jump forward 2 hours and 30 minutes.
“Jump backward 5 minutes.” The audio stream will jump backward 5 minutes.
You can also set a jump default time. Like in the previous examples, first pause the narration, then say “Set default jump forward to 5 minutes,” or “Set default jump back to 10 minutes,” whatever amount of time you wish to set as your default.
In an example where you set your default jump time to 5 minutes, test your new setting, say, “Lady A, pause.” After your smart speaker asks “What now?”, say “Jump forward.” Your speaker will say “Jumping forward 5 minutes.” The audio will then resume.
