Installation

npm install @picovoice/leopard-node

AccessKey

Leopard requires a valid Picovoice AccessKey at initialization. AccessKey acts as your credentials when using Leopard SDKs. You can get your AccessKey for free. Make sure to keep your AccessKey secret. Signup or Login to Picovoice Console to get your AccessKey.

Usage

Create an instance of the engine and transcribe an audio file:

const Leopard = require("@picovoice/leopard-node");

const accessKey = "${ACCESS_KEY}" // Obtained from the Picovoice Console (https://console.picovoice.ai/)
const handle = new Leopard(accessKey);

const result = engineInstance.processFile('${AUDIO_PATH}');
console.log(result.transcript);

Replace ${ACCESS_KEY} with yours obtained from Picovoice Console and ${AUDIO_PATH} to the path an audio file. Finally, when done be sure to explicitly release the resources using handle.release().

Demos

Leopard Node.js demo package provides command-line utilities for processing audio using leopard.
