The IMS Toucan system for the Blizzard Challenge 2021

Florian Lux, Julia Koch, Antje Schweitzer, Ngoc Thang Vu

For our contribution to the Blizzard Challenge 2021, we built a non-autoregressive speech synthesis system that transforms phoneme inputs from a phonemiser into spectrogram frames. A GAN based vocoder then transforms the spectrogram into a waveform. We handle code-switching by altering the phonemiser based on the output of a language identification system. Non-native phonemes are manually mapped to their closest native representation. An interactive demo is available.
