With the development of AI, composing music by AI keeps prospering. However, sometimes we struggle with the lyrics, which play an important role to form more delicate expressions. Unfortunately, there are limited researches on lyrics generation. Among these researches, there is only one for Chinese lyrics generation. Since Chinese is the second most used language in the world, there should be a huge demand for Chinese lyrics composition. In our work, we demonstrate how a Chinese lyrics generator based on Sequence to Sequence can support those who are out of ideas for writing Chinese lyrics. Other than typically used word embedding and word2vec, we also introduced a pronunciation vector in our model. Our pronunciation vector consists of Chinese Bopomofo phonetic spelling for Chinese words and International Phonetic Alphabet for English words appearing sometimes in Chinese compositions. Demonstrated by the experimental results, our model with word2vec and pronunciation vector can generate catchier lyrics with fluency.
