The SIGMORPHON 2020 Shared Task on Multilingual Grapheme to Phoneme Conversion
We describe the design and findings of the SIGMORPHON 2020 shared task on multilingual grapheme to phoneme conversion. Participants were asked to submit systems which take in a sequence of graphemes in a given language as input, then output a sequence of phonemes representing the pronunciation of that grapheme sequence. Nine teams submitted a total of 23 systems, at best achieving a 18% relative reduction in word error rate (macro averaged over languages) versus strong neural sequence to sequence baselines. To facilitate error analysis, we publicly release the complete outputs for all systems a first for the SIGMORPHON workshop.
