I have a JavaScript code here:

var SpeechRecognition = SpeechRecognition || webkitSpeechRecognition;
var recognition = new SpeechRecognition();
recognition.onstart = function(){
    console.log("Started recording");
}
recognition.onspeechend = function() {
    recognition.stop();
}
recognition.onresult = function(event){
    var transcript = event.results[0][0].transcript;
    var confidence = event.results[0][0].confidence;
    console.log(transcript);
};
recognition.start();

It will work with all languages (I checked with English and Spanish). I can add language with recognition.language = "<langcode>" but I want to add two language to this:recognition.language = ["en-US","es-MX"] (English and Spanish) because sometimes it will mistake with another language.
