Lily is designed to comprise interactive conversations, real-time translation, vocabulary voice games, and a Chinese voice assistant. Interactive conversations allow you to practice your speech through regular conversations with Lily, which uses speech recognition and synthesis to reply with a human voice, detects pronunciation errors and improve the accent. Lily was built based on training programs of HSK, the Chinese Proficiency Test, and designed for any skills level from beginner to advanced, with a curriculum that can be personalized.
