Voice recognition is one of those Chromium features that uses Google API. You must enable Speech API and billing, otherwise voice recognition will not work.

Once you enable Speech API and billing, you can provide the keys to JxBrowser Chromium engine using one of the approaches described in the Chromium API Keys article.

The following example demonstrates how to configure Chromium with your API keys and test voice recognition functionality:

import com.teamdev.jxbrowser.chromium.Browser;
import com.teamdev.jxbrowser.chromium.BrowserPreferences;
import com.teamdev.jxbrowser.chromium.swing.BrowserView;

import javax.swing.*;
import java.awt.*;

 * The sample demonstrates how to enable voice recognition functionality in Chromium
 * engine. By default, voice recognition functionality is disabled. To enable it you must
 * provide your Google API Keys to Chromium engine as shown in the example.
public class VoiceRecognitionSample {
    public static void main(String[] args) {
        BrowserPreferences.setChromiumVariable("GOOGLE_API_KEY", "My API Key");
        BrowserPreferences.setChromiumVariable("GOOGLE_DEFAULT_CLIENT_ID", "My Client ID");
        BrowserPreferences.setChromiumVariable("GOOGLE_DEFAULT_CLIENT_SECRET", "My Client Secret");

        Browser browser = new Browser();
        BrowserView view = new BrowserView(browser);

        JFrame frame = new JFrame();
        frame.add(view, BorderLayout.CENTER);
        frame.setSize(700, 500);
