Model Card for mhubert-base-25hz

This is a version of Hubert by Meta. This version was introduced in TWIST and showed lots of value as a speech tokeniser for training SpeechLMs.

These model weights were converted by SLP-RL from the original Textlesslib release.

Model Details

Model Description

This Hubert model was introduced in TWIST we encourage you to look there for the full details.

It was trained on a varied mixture of datasets: Multilingual LS, Vox Populi, Common Voice, Spotify, and Fisher. This Hubert base model was trained for 3 iterations with the default 50Hz features rate. For the 4-th iteration, they add an additional convolutional layer at the CNN Encoder with the stride 2, resulting in features of 25Hz.

We converted the original Fairseq release to Huggingface🤗 using the conversion script, after adding support, and asserted that the results are identical.

Uses

This is a base HubertModel and as such is useful as a feature extractor for speech tokenisation for usages such as Spoken Language Modelling or Speaking Style Conversion.

How to Get Started with the Model

This model currently requires a a clone of the transformers repository, but will be integrated to the package in coming updates soon. Use version transformers>=??, so make sure you have it installed. Afterwards it can be used as follows:

from transformers import HubertModel
model = HubertModel.from_pretrained('slprl/mhubert-base-25hz')
