CyberTyper

A ReactJS component for automatically typing text like a typewriter synchronized with Speech Synthesis (using jaxcore-say) and Speech Recognition (coming soon).

Examples:

• Blade Runner 2049 interogration

Usage:

yarn install cybertyper

Include:

import CyberTyper from 'cybertyper';
import Say from 'jaxcore-say';
Say.setWorkers({
    'espeak': 'webworkers/espeak-en-worker.js'
});
const voice = new Say({
    language: 'en-us',
});

Jaxcore Say WebWorkers

The say library is used for speech synthesis. The webworker file set in setWorkers() must be copied to the public html directory (eg public/webworkers):

espeak-en-worker.js can be downloaded from here

Create a "script"

A CyberTyper script is an array of lines which will be speech synthesized and typed:

const cyberTyperScript = [
    {
        text: 'A quick brown fox',
        linebreak: true
    },
    {
        text: 'jumped over', 
        linebreak: true
    },
    {
        text: 'the lazy dog.', 
        linebreak: true
    }
];

linebreak: true adds an additional line break after the line is typed.

Different jaxcore-say voice profiles can be defined for each line:

const cyberTyperScript = [
    {
        text: 'I am Cylon',
        speaker: {
            voice: 'Cylon'
        }
    },
    {
        text: 'I am Leon',
        speaker: {
            voice: 'Leon'
        }
    }
];

A display name and custom CSS class can be specified for each line:

const cyberTyperScript = [
    {
        text: 'I am Cylon',
        speaker: {
            voice: 'Cylon',
            name: 'Cylon',
            className: 'cyloncss'
        }
    },
    {
        text: 'I am Leon',
        speaker: {
            voice: 'Leon',
            name: 'Leon',
            className: 'roycss'
        }
    }
];

Component Usage

<CyberTyper
    script={cyberTyperScript}
    maxLines={15}
    lineBreakDuration={200}
    hideCursorWhenDone={true}
    onComplete={() => {
        console.log('CyberTyper complete');
}}/>

Beware: web browsers disable JavaScript AudioContext usage until after a user action. So <CyberTyper/> should be rendered after a mouse click or keyboard action.

Custom CSS

The <CyberTyper/> component does not include any CSS of it's own. But the DIV and SPAN elements have .CyberTyper classes defined which can be used to customize how the generated lines look, including the styling of a cursor and names.
