A plugin for detecting speech events in audioContext instances

Hosted in Github 🐙

This library drives the speech events detected on Accent.ai.

Syntax

Constructor

var speechEvents = new speechEventsConst({
                         speechStatusCB: (status) => {
                           console.log(status);
                         },
                         speechDetectionAllowedDelay: 1000,
                         speechDetectionThreshold: 40,
                         speechDetectionMaximum: this.recordingMaxLength,
                       });

Creates a speech events analyzer instance.

Development

This package can be used both as an ES6 Node.js module and a Browser library.

Node.js imports use the file src/speech-events.js.

NOTE: Currently this package can only be used under Node.js apps compatible with ES6.

Webpack is used to build the browser-compatible lib/speech-events.js file which is later uglified (using uglify-js) into dist/speech-events.min.js.

Scripts

The following scripts are defined within package.json for ease of development:

npm run lint

npm run build

For more info on how these work simply checkout the script definitions within package.json.

TODO

• Add jasmine tests
• Make Node.js module version which is compatible with non ES6 apps.
