1. Word bank for constructing the sentence

- Distinguish recognition of individual sounds from sequence retention.

- [Duolingo](https://blog.duolingo.com/duolingo-101-how-to-learn-a-language-on-duolingo/)

## How it works

Remember material and reproduce or transform it under a rule.

## Variants

### Memory

<a id="family-17-branch-1"></a>

- Repeat tones, words, noises or directions. <a id="family-17-branch-1-variant-1"></a>
- Reproduce a growing sequence. <a id="family-17-branch-1-variant-2"></a>
- Remember sound pairs and find matches. <a id="family-17-branch-1-variant-3"></a>
- Retain instructions until they can be used. <a id="family-17-branch-1-variant-4"></a>

### Transformation

<a id="family-17-branch-2"></a>

- Repeat a sequence in reverse. <a id="family-17-branch-2-variant-1"></a>
- Sort heard elements by a property. <a id="family-17-branch-2-variant-2"></a>
- Reproduce only elements of a selected category. <a id="family-17-branch-2-variant-3"></a>
- Shift rhythm, transpose pitch or replace elements under a rule. <a id="family-17-branch-2-variant-4"></a>

### Changes and omissions

<a id="family-17-branch-3"></a>

- Find a missing sound or word. <a id="family-17-branch-3-variant-1"></a>
- Identify an element changed between listens. <a id="family-17-branch-3-variant-2"></a>
- Continue a sequence using an inferred rule. <a id="family-17-branch-3-variant-3"></a>
- Restore a sequence from fragments heard at different times. <a id="family-17-branch-3-variant-4"></a>

## Context and limits

A working design-space map: 27 families, 81 branches and 324 variants. Voice control, audio-based play and communication can combine or exist separately. Released-game examples support particular techniques; supplementary combinations are design proposals.
