If you feel that the conversion is too small and uncomfortable to use, you can find a text-to-speech conversion assistant in the browser or app store, and then use it to help you convert. Details are as follows:
Go to the browser or app store to find the software of the text-to-speech assistant first.
Then install it on the mobile phone. When you open it, you will see a "+"button below. Click on it to see two options, namely, import file and create new text. The former is to convert the previous text document into speech, and the latter is to input the text immediately and convert it into speech. You can order it according to your own needs.
After you select it, it begins to recognize. This time depends on the size of the file you want to convert, but it is not long.
After the identification is completed, you can preview the audition. If you can, just click Save in the upper right corner. After saving, you can view it at any time.
