It seems that Google will start selling audiobooks in its Google Play store. Earlier, while studying APK, the Android Police resource found signs of audiobooks on Google Play. The study of APK was continued by the Android Soul resource. This was the last update to the Google Play Books app. As a result, the code was found for several new functions, including for audiobooks. ![2_Google_Play_audiobooks_banner_1.jpg](https://steemitimages.com/DQmQVSn8LrqP7efjmVjG2QXRWuRWg5aTV6BiCdPqSzcZtbt/2_Google_Play_audiobooks_banner_1.jpg) The new service is based on Google's research on the "training" of machine learning models in order to design models that perform certain tasks. By creating a system that builds its own models, Google hopes to make advanced machine learning systems more accessible to conventional developers, which will no longer require a full set of skills. Machine learning systems that create customized models, especially in the field of visual content, are not completely new. The peculiarity of the new service is that models are created without human intervention.
