## How it works

Reproduce a recognizable sound pattern.

## Variants

### Phonetics

<a id="family-09-branch-1"></a>

- Produce a required vowel, consonant or syllable. <a id="family-09-branch-1-variant-1"></a>
- Distinguish close phonemes and select the corresponding action. <a id="family-09-branch-1-variant-2"></a>
- Emphasize stress or an articulatory accent. <a id="family-09-branch-1-variant-3"></a>
- Change vocal shape while keeping pitch steady. <a id="family-09-branch-1-variant-4"></a>

### Imitation

<a id="family-09-branch-2"></a>

- Imitate an animal, machine or instrument. <a id="family-09-branch-2-variant-1"></a>
- Imitate a fictional character's voice using specified properties. <a id="family-09-branch-2-variant-2"></a>
- Reproduce laughter, growling, whistling or another recognizable signal. <a id="family-09-branch-2-variant-3"></a>
- Make a sound another player must identify. <a id="family-09-branch-2-variant-4"></a>

### Performance style

<a id="family-09-branch-3"></a>

- Read a line with a specified fictional mood. <a id="family-09-branch-3-variant-1"></a>
- Alternate voiced, whispered and sung delivery. <a id="family-09-branch-3-variant-2"></a>
- Maintain an acoustic disguise through range, rhythm and timbre. <a id="family-09-branch-3-variant-3"></a>
- Choose delivery style as a separate game parameter. <a id="family-09-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.
