Amazon has confirmed that developers can now earn money for creating Alexa skills across more skill categories.

Alexa is Amazon’s intelligent personal assistant software designed to run in line with the firm’s own ‘smart’ speaker, Echo. Skills are chunks of software that drive voice driven application functionalities on the Alexa platform.

Each month, developers of skills in eligible categories with the highest customer engagement in the US, UK, and Germany are paid by Amazon.

In May 2017, Amazon began rewarding developers of top skills in the Games, Trivia & Accessories category.

The firm has now added six more categories: Education & Reference, Food & Drink, Health & Fitness, Lifestyle, Music & Audio and Productivity.
