Failure to select text is a clue rather than a complete diagnosis, because the viewer or document restrictions can also affect selection. OCR accuracy also varies with scan quality, page rotation, and layout.
Adobe’s PDF accessibility explanation distinguishes recognizable text from static scanned images. For listening, the practical goal is to obtain accurate text first; a different voice cannot repair missing or incorrectly recognized words.
