Features : ~ Learning effectiveness: We algorithmically adjust the amount of repetition and new information based on user's performance. We believe that this can improve learning effectiveness. ~ Relevance and diversity: The learning program consists of 24 backyard birds. We believe that our choice of birds offers an optimal amount of diversity and relevance to backyard bird-watchers. ~ Fun and relaxing interaction: We model the request-response as a continuous conversation. We believe that it is a fun and relaxing way to acquire information. ~ Free : It is free. Instructions : * You can answer by just saying the name of the bird, e.g. hummingbird, jay, crow, etc. * If you want to answer before the audio finishes playing, you need to interrupt by saying "OK Google." first and then proceed with your answer. * If you don't know the answer, you can say "I don't know" or "Tell me the answer" to get the answer. * If you want to hear the bird sound again, you can say "Repeat". * If you want to know your progress, you can say "Tell me my score". * If you want to quit the game, you can say "Goodbye".
