A new AI system called DeepSinger has been developed by Microsoft Research in collaboration with Zhejiang University in China. As the name suggests, the core ability of an artificial intelligence model is that it can generate voices for singing. In fact, this can be done in more than one language.

In this paper1, we develop DeepSinger, a multi-lingual multi-singer singing voice synthesis (SVS) system, which is built from scratch us-ing singing training data mined from music websites. The pipeline of DeepSinger consists of several steps, including data crawling,singing and accompaniment separation, lyrics-to-singing alignment, data filtration, and singing modeling.
Specifically, we design a lyrics-to-singing alignment model to automatically extract the duration of each phoneme in lyrics starting from coarse-grained sentence level to fine-grained phoneme level, and further design a multi-lingual multi-singer singing model based on a feed-forward . Transformer to directly generate linear-spectrograms from lyrics,and synthesize voices using Griffin-Lim. DeepSinger has several advantages over previous SVS systems:
1) to the best of our knowledge, it is the first SVS system that directly mines training datafrom music websites.
2) the lyrics-to-singing alignment model further avoids any human efforts for alignment labeling and greatly reduces labeling cost.
3) the singing model based on a feed-forward.Transformer is simple and efficient, by removing the complicated acoustic feature modeling in parametric synthesis and leveraging a reference encoder to capture the timbre of a singer from noisy singing data.
4) it can synthesize singing voices in multiple languages and multiple singers.
We evaluate DeepSinger on our mined singing dataset that consists of about 92 hours data from 89 singers on three languages (Chinese, Cantonese and English). The results demonstrate that with the singing data purely mined from the Web, DeepSinger can synthesize high-quality singing voices in terms of both pitch accuracy and voice naturalness.
