react-speech

React component for the Web Speech api.

The Web Speech API aims to enable web developers to provide, in a web browser, speech-input and text-to-speech output.

The Web Speech API comes in two parts, speech synthesis and speech recognition. This react component supports speech synthesis, text-to-speech.

Simple Usage

Using react-speech, is pretty simple, simply React.render the speech component, setting the text property, which is rendered to speech.

  import React from 'react';
  import Speech from 'react-speech';

  React.render(
    <Speech text="Welcome to react speech" />,
    document.getElementById('node')
  );

Speech Component API

Here is the full API for the <Speech> component, these properties can be set on an instance of Speech:

Styles

If you would like to override the default styles, simply pass in a style object. react-speech like React uses inline styles whose key is the camelCased version of the style name, and whose value is the style's value, usually a string.

const style = {
  container: { },
  text: { },
  buttons: { },
  play: {
    hover: {
      backgroundColor: 'GhostWhite'
    },
    button: {
      cursor: 'pointer',
      pointerEvents: 'none',
      outline: 'none',
      backgroundColor: 'Gainsboro',
      border: 'solid 1px rgba(255,255,255,1)',
      borderRadius: 6
    }
  },
  pause: {
    play: { }
    hover: { }
  },
  stop: {
    play: {
    hover: { },
    button: { }
  },
  resume: {
    play: {
    hover: { },
    button: { }
  }
};
