Wav2vec2 results vary depending on far away prefix len
Here is the results of decoding part of audio, containing “Waterloo station” text with wav → IPA model (facebook/wav2vec2-lv-60-espeak-cv-ft) depending on the prefix and suffix len. The text itself contains in [6.3s → 7.8s] chunk of audio. The other wav2vec2 models show similar behaviour - the decoding results are vary depending on far away prefixes. The results are the same for pure model code without CTC and for full hg pipeline with CTCSTART_TIME → END_TIME DECODED_TEXT6.0    →   8.0    wɔːtɚluːsteɪʃən   <<< the correct output5.5    →   8.5    bɔtɚluːsteɪʃən5.0    →   9.0    bɔːtɚluːsteɪʃən4.5    →   9.5    wɔːtɚuːsteɪʃən4.0    →   10.0   vɔtɚvuːsteɪʃən3.5    →   10.5   wɔːtɾɚwuːsteɪʃən3.0    →   11.0   wɔːtɾɚwuːsteɪʃən2.5    →   11.5   wɔːtɚwuːsteɪʃən2.0    →   12.0   wɔːtɾɚvuːsteɪʃən1.5    →   12.5   wɔtɚvuːsteɪʃən1.0    →   13.0   voːtɚvuːsteɪʃən0.5    →   13.5   voːtɚvuːsteɪʃənWhat can be the reason?
