Practice, the voice recorder and the Listen button need the browser's permission to use the microphone. When the browser asks, choose Allow. If you said no earlier, look for the microphone or lock icon in the address bar and turn it back on, then reload the page.
The Listen button reads Type a command when the browser cannot turn speech into text at all (some browsers do not offer it); the typed box under it works everywhere. Where it can listen, it says Listening while the microphone is on and stops by itself at the end of the sentence; if it heard nothing, it says so and asks to try again.
