  1. Sounds like a great addition and obviously a necessity to have on all websites in the near future but, for us who are not developers/programmers, you really didn’t give a good description of how we add it to our scripts.
    Also, I’m not really sure if this would work on E-Commerce platforms such as;
    I’d really like to hear more about this and have a better description of how to install the script.

    • This script develop to run on any WordPress website. You can easily embed this code in your website. First login into your WordPress dashboard and navigate to appearance add custom HTML widget and paste all code which you can copy in our website and last save the widget.

      • Hi i tried to install voice search with the html widget. i did copy and paste, but i didn’t see the display in my site. i tried 2 times with footer and secondary widget.this code got error reply in img , (you need to add alt text) and delete border in css ( it will be too big). can you send more details

        • I tried this script one more time and this script work perfectly, if you got error in your HTML editor like alt text (you need to add alt text) and CSS border ( it will be too big) just ignore that. It doesn’t effect the code. If you can’t see anything in your site after embed the code may be due to catch plugin. Please purge all catch in your website and see that it work or not.

  2. hey.. it is giving me the exact same interface as yours but is not taking the voice as input. When i click on the microphone, basically nothing happens. I tried on your site it works perfectly there. pls tell me what to do its really urgent for my FYP 🙁
