My read out laud option is not working instead it is asking me to enable text to speech engine, I have tried every possible way but I do not know how to enable it, so that it will start to read the text again laud. Please help me 🙏🙏

I actually like the abode reader app to read the text out laud to me. Earlier it was functioning properly, but now when I select the text and click on the read out laud option it is not reading it instead it is showing me that i need to enable the text to speech engine in order to listen to the text. I have tried many ways to find that option but I cannot find it. So, please suggest me how can i again enable the read out laud function on my app.
