Even after all this, the quality of the produced audio file may be subpar.
Not to mention, the valuable hours dedicated to the entire process. For years, creating good voice overs meant investing hundreds if not thousands of dollars in hiring voice artists, renting a recording studio to get the script recorded, investing in expensive recording equipment (if you are recording from home), and recruiting or outsourcing the entire project to an audio editor to mix the audio and produce a high-quality voiceover.
