The goal of the project is to help you practice listening comprehension.

It works by giving you random sentences in the language you're learning and asking you to fill in the gaps. The sentences were submitted by contributors to Mozilla Common Voice platform.

The project aims to not require any knowledge of a meta language in order to start learning. If you are interested in a more traditional course creation project, check out LibreLingo.

The game works by ordering the questions by difficulty, then you are given batches of five with a random task for each of the questions. When you sucessfully answer a batch of five in less time than the audio takes to play, then you advance a level and get given a new batch of five.

• Fill in the blanks: A cloze-style task
• Drag and drop: Get a set of tiles and click on them to build a word or sentence
• Pick the right one: Get two options and choose the right one
• Spot the word: Get set of six tiles and click on the ones that appear in the audio

• Space: Play the recording
• Enter:
  1. Submit and check if you got it right
  2. If already submitted, move to the next recording

The data comes from the Common Voice dataset releases.

This system is designed with two main user groups in mind:

• People who want to learn a new language
• People who want to learn how to write their native language

The system endeavours to be audio first, with knowledge of writing built up by hearing.
