<p>This sample is a phone application that provides a chat experience in which
users can respond to messages with a quick voice response. New messages create
a notification with a "Reply" action. The notification is bridged from phone
to wearable, and selecting the "Reply" action on the wearable opens the voice
transcription UI allowing the user to speak a response.</p>

<p>To keep the example simple and self-contained, instead of a real chat
application (which would require a server or a peer-to-peer connection), the
conversation is conducted with an chat bot on the phone. Each time the bot
responds, the phone app updates the notification and allows the user to write
back. This sample is primarily intended to demonstrate the voice-reply
capabilities provided by the Android Wear notification API.</p>

<p>When using the emulator you can type a response instead of speaking it
aloud. To allow typed responses, ensure that your emulator image has the
"hardware keyboard present" option enabled. After typing your message into
the emulator window, hit the enter key and wait a few seconds for your
message to be sent.</p>
