Digital badges are a validated indicator of accomplishment, skill, quality or interest that can be earned in various learning environments.

Open Badges is the name of a group of specifications and open technical standards originally developed by the Mozilla Foundation with funding from the MacArthur Foundation.

The Open Badges standard describes a method for packaging information about accomplishments, embedding it into portable image files as a digital badge, and establishing an infrastructure for badge validation.

The standard was originally maintained by the Badge Alliance Standard Working Group, but transitioned officially to the IMS Global Learning Consortium.

Educational technology is defined by the Association for Educational Communications and Technology as "the study and ethical practice of facilitating learning and improving performance by creating, using, and managing appropriate technological processes and resources".

Speech recognition (SR) is the inter-disciplinary sub-field of computational linguistics that develops methodologies and technologies that enables the recognition and translation of spoken language into text by computers.

It is also known as "automatic speech recognition" (ASR), "computer speech recognition", or just "speech to text" (STT).

It incorporates knowledge and research in the linguistics, computer science, and electrical engineering fields.

A skill is the ability to carry out a task with pre-determined results often within a given amount of time, energy, or both.

Skills can often be divided into domain general and domain-specific skills.

For example, in the domain of work, some general skills would include time management, teamwork and leadership, self-motivation and others, whereas domain-specific skills would be useful only for a certain job.

Skill usually requires certain environmental stimuli and situations to assess the level of skill being shown and used.
