## Wav2Vec2-Large-XLSR-53 pretrained on Ainu language data |
|
|
|
This is a [wav2vec-large-xlsr-53](https://huggingface.co/facebook/wav2vec2-large-xlsr-53) model adapted for the Ainu language by performing continued pretraining for 100k steps on 234 hours of speech data in Hokkaido Ainu and Sakhalin Ainu. |
|
For details, please refer to the [paper](https://arxiv.org/abs/2301.07295). |
|
|
|
A model fine-tuned for automatic transcription of Sakhalin Ainu is also available: [wav2vec2-large-xlsr-53-ain-sakh](https://huggingface.co/karolnowakowski/wav2vec2-large-xlsr-53-ain-sakh). |

abstract = {In recent years, neural models learned through self-supervised pretraining on large scale multilingual text or speech data have exhibited promising results for underresourced languages, especially when a relatively large amount of data from related language(s) is available. While the technology has a potential for facilitating tasks carried out in language documentation projects, such as speech transcription, pretraining a multilingual model from scratch for every new language would be highly impractical. We investigate the possibility for adapting an existing multilingual wav2vec 2.0 model for a new language, focusing on actual fieldwork data from a critically endangered tongue: Ainu. Specifically, we (i) examine the feasibility of leveraging data from similar languages also in fine-tuning; (ii) verify whether the model’s performance can be improved by further pretraining on target language data. Our results show that continued pretraining is the most effective method to adapt a wav2vec 2.0 model for a new language and leads to considerable reduction in error rates. Furthermore, we find that if a model pretrained on a related speech variety or an unrelated language with similar phonological characteristics is available, multilingual fine-tuning using additional data from that language can have positive impact on speech recognition performance when there is very little labeled data in the target language.} |
