Hi,  
I’m thinking about training wav2vec2 model for Japanese.  
And I have a question.  
Do we need Wav2Vec2FeatureExtractor as well?  
Or can we use Wav2Vec2FeatureExtractor for any languages?

Thanks in advacne.

[Found answer]It seems there are 2 kinds of feature extractors.  
1st one is just normalize raw audio and 2nd one is part of architecture.  
Since 1st one is just normalizing raw audio, I don’t think we need to train it.
