The Blizzard Challenge 2021

Zhen-Hua Ling, Xiao Zhou, Simon King

The Blizzard Challenge 2021 is the seventeenth annual Blizzard Challenge. A European Spanish dataset was provided to participants this year and two tasks were designed. The hub task is to synthesize texts containing only Spanish words. The spoke task is to synthesize Spanish texts containing a small number of English words in each sentence. Twelve and ten teams submitted their results for these two tasks, respectively. Listening tests were conducted online to evaluate the naturalness, intelligibility and speaker similarity of the synthetic speech. In addition to these conventional metrics, the subjective acceptability of the English words in Spanish sentences was measured for the spoke task. The top system in the hub task achieved comparable naturalness with, and better speaker similarity than, the natural reference speech.
