    Hotword

    Description

    This is the project Porcupine (https://github.com/Picovoice/Porcupine)'s Node.js wrapper.

    It's easy to use, and fit almost every platform because it run on WASM.

    Usage

    Following is the example (it is test.js in the package):

    let fs=require("fs");
    let wavdecoder=require("wav-decoder");
    let pico=require(__dirname+"/pico.js");
    
    wavdecoder.decode(fs.readFileSync("multiple_keywords.wav")).then((wav)=>{
            let piko=new pico({
                grapefruit:fs.readFileSync(__dirname+"/prekeywords/grapefruit_wasm.ppn"),
                bumblebee:fs.readFileSync(__dirname+"/prekeywords/bumblebee_wasm.ppn")
            },wav.sampleRate,(word)=>{
                console.log(word);
            })
    
            piko.init().then(()=>{
                    
                    for(let i=0;i<wav.channelData[0].length;i+=1024)
                    piko.feed(wav.channelData[0].slice(i,i+1024));
                
            });
    
    });
    

    Just decode the wav and feed it to the 'pico' instance,
    the we can get the keyword on callback function.

    Additionally, if you want a live hot word detection,just start a
    recorder then feed the 'pico' with audio frame data.

    Run a test

    npm run test
    

    if success, you gonna get this

    bumblebee
    grapefruit
    

    Get a keyword file
