Hi
Sorry for the delay in response.

Use the Read Out Loud Text-to-Speech tool
Read Out Loud is a Text-to-Speech (TTS) tool that is built in Acrobat Reader DC. The Read Out Loud feature reads aloud the text in a PDF, including the text in comments and alternate text descriptions for images and fillable fields. In tagged PDFs, content is read in the order in which it appears in the document’s logical structure tree. In untagged documents, the reading order is inferred, unless a reading order has been specified in the Reading preferences.
Read Out Loud uses the available voices installed on your system. If you have SAPI 4 or SAPI 5 voices installed from text-to-speech or language applications, you can choose them to read your PDFs.
To use Read Out Loud, you need Acrobat Reader DC and a Text-to-Speech engine installed on your system. Acrobat Reader must have a voice selected that you have installed. Also, the document must be accessible, otherwise it is not read at all or it is read in the wrong order.
To verify your settings in Acrobat Reader:
Go to the Preferences dialog box of Acrobat Reader by selecting Edit > Preferences. In the left pane, select Reading. In the right pane, deselect the Use Default Voice and select a voice from the drop-down list that you have verified installed on your computer.
