Voice coaching experiment

A voice coach that runs on a company server. It detects mistakes, explains them and asks the learner to try again.

How the coach corrects a learner, on the company’s own server.

I tested self-hosted voice coaching with a coach editor, a learner app, APIs, an SDK and installation tools.

What it contributed or taught me

Product design, coach editor, APIs and installation.

What I built

  • Coach editor. Create, test and publish coaches.
  • Learner app. Speak with a coach and review feedback.
  • Installation. Install and operate the services with Docker Compose.
