APPINVENTOR EXTENSION

I need someone to develope an extention for appinventor, enhance the "speech recognizer" I am making a Voice Menu, which the user can press a button and speak the food he likes, and the Menu search from the database and found the result for him. I use speech recognizer to do this function, when the button is touch, trigger the speech recognizer to listen, after listening, use the result to search. however, there is not a quiet place in a restaurant, the speech recognizer keep on listening and make the process very slow, usually even cannot finish the listening. I want to improve this user experience. I see there is a function stoplistening() in the following page: [login to view URL]() My idea: press down the button to start listening, and when the button press up, call this stoplistening() function manually, like what is now happening in whatsapp voice. I need someone to making this extension
