🚧 Browser Client v2.0 is a breaking change. Read more about the major changes and how to upgrade from our blog: https://speechly.com/blog/speechly-browser-client-v2-released
With the browser-client you can add voice features to any website. It handles authentication, audio capture, network streaming and connection management with the Speechly Voice API.
Check out the browser-client-example repository for a demo app built using this client.
NOTE: If you are using React, you can use our React client instead. It provides the same functionalities, but provides a programming model that is idiomatic to React.
Install the package:
# Using Yarn
yarn add @speechly/browser-client
# Using NPM
npm install --save @speechly/browser-client
Start using the client:
import { BrowserClient, BrowserMicrophone, Segment } from '@speechly/browser-client'
// Create a new client.
// NOTE: Configure and get your appId from https://api.speechly.com/dashboard
// NOTE: Set vad.enable to true for hands free use
const client = new BrowserClient({
appId: 'your-app-id'
vad: { enabled: false, noiseGateDb: -24.0 }
})
// Create a microphone
const microphone = new BrowserMicrophone()
// Initialize the microphone - this will ask the user for microphone permissions
// and establish the connection to Speechly API.
// Make sure you call `initialize` from a user action handler
// (e.g. from a button press handler).
await microphone.initialize()
// bind the microphone to the client
await client.attach(microphone.mediaStream)
// React to the updates from the API.
client.onSegmentChange((segment: Segment) => {
console.log('Received new segment from the API:',
segment.intent,
segment.entities,
segment.words,
segment.isFinal
)
})
// Start recording.
// This can be bound to e.g. a button press.
await client.start()
// Stop recording after a timeout.
// This can be bound to e.g. a button press.
setTimeout(async function () {
await client.stop()
}, 3000)
This sample HTML loads Speechly's browser-client ES modules via a CDN that mirrors npm packages. The page displays a text field that you dictate text into. See browser's console log for raw segment feed from Speechly.
Please use a HTML server to view the example. Running it as a file will not work due to browser's security restrictions. For example run serve . on command line and open localhost:3000 in your browser.
