Voice Conversion Challenge 2018
We are glad to invite you to participate in the 2nd Voice Conversion Challenge to compare different voice conversion systems and approaches using the same voice data.
The previous challenge can be accessed below:
Tasks of the 2nd Challenge
The objective is speaker conversion, which is a well-known basic problem in voice conversion. We have prepared two tasks:
Other voices of the same source speakers will be provided later as test data consistsing of around 50 sentences for each speaker. Each participant will generate converted voices from them using the developed 16 conversion systems.
The resulting 16 converted voice sets will be evaluated in terms of perceived naturalness and similarity through listening tests.
- Hub task (main task): parallel training
- We will provide voices of 4 source and 4 target speakers (consisting of both female and male speakers) from fixed corpora as training data. Each speaker utters the same sentences set consisting of around 80 sentences.
- Using these parallel data sets, voice conversion systems for all speaker-pair combinations (16 speaker-pairs in total) will be developed by each participant.
- Spoke task (optional task): nonparallel training
- We will also provide voices of other 4 source speakers (consisting of both female and male speakers) from fixed corpora as training data. Each speaker utters another sentences set consisting of around 80 sentences. The target speakers are the same as in the hub task. Therefore, the sentence set of the source speakers is different from that of the target speakers.
- Using these nonparallel data sets, voice conversion systems for all speaker-pair combinations (16 speaker-pairs in total) will be developed by each participant.
We focus on 22.05 kHz speech and signal-to-signal conversion strategies. No transcriptions will be provided for the test set, and the use of manual annotations is NOT allowed (check the rules section for more detailed information). Participants are free of using additional data (for training purposes).
The tentative schedule is as follows:
- October 1st: release of training data
- December 1st: release of evaluation data
- December 8th: deadline to submit the converted audio.
- January 26th: notification of results
