HuBERT-large-SLURP

This model is a fine-tuned version of facebook/hubert-large-ls960-ft on the SLURP dataset for the intent classification task.

Model description

The base Facebook's Hubert model pretrained on 16kHz sampled speech audio. When using the model make sure that your speech input is also sampled at 16Khz.

Task and dataset description

Intent Classification (IC) classifies utterances into predefined classes to determine the intent of speakers. The dataset used here is SLURP, where each utterance is tagged with two intent labels: action and scenario.

Usage examples

You can use the model directly in the following manner:

import torch
import librosa
from transformers import AutoModelForAudioClassification, AutoFeatureExtractor

## Load an audio file
audio_array, sr = librosa.load("path_to_audio.wav", sr=16000)

## Load model and feature extractor
model = AutoModelForAudioClassification.from_pretrained("alkiskoudounas/hubert-large-slurp")
feature_extractor = AutoFeatureExtractor.from_pretrained("facebook/hubert-large-ls960-ft")

## Extract features
inputs = feature_extractor(audio_array.squeeze(), sampling_rate=feature_extractor.sampling_rate, padding=True, return_tensors="pt")

## Compute logits
logits = model(**inputs).logits
