<!-- 
    This is an example of two ways to do extended listening. 
    1. The first example, loop, simply loops listening until a certain stop word is said (hardcoded in this example, you probably want to use grammar in a real scenario).
    2. The second example, timer, gives the user 20 seconds to answer. The only scenario we recommend using this for is if you have a very noisy environment and you can't rely on speech recognition. In order to actually capture speech here, you need to record the audio aswell - which can be done with the audio logging tool.
