Play.ht is a service that reads the content of your blog posts or pages and allows the user to play an audio version.
The AI is pretty good. To my ear, Mia (neural) sounds the most realistic.
Other post to audio options are available.
You can even export your audio and upload it to your favourite podcast service.
Using a service such as Play.ht means that your website content becomes accessible to more people and gives some of your users different ways to consume your content.
