SeamlessM4Tv2-Large Speech Encoder

This repository carves out the speech encoder from SeamlessM4Tv2-Large, which performs strongly on cross- and multilingual sequence-level audio classification tasks (cf. results on SIB-Fleurs available here).

All credits go to the original SeamlessM4Tv2-Large Team.

Example Usage

You can use both AutoModel and AutoModelForAudioClassification (or AutoModelForSequenceClassification, if you prefer) with this repository:

python

# best to use both feature extractor and model with GPU!
from datasets import load_dataset
from transformers import (
    AutoModel,
    AutoModelForAudioClassification,
    AutoFeatureExtractor,
)
import torch
import torchaudio

device = "cuda:0"

feature_extractor = AutoFeatureExtractor.from_pretrained(
    "WueNLP/seamless-m4t-v2-large-speech-encoder", trust_remote_code=True
)
model = AutoModel.from_pretrained(
    "WueNLP/seamless-m4t-v2-large-speech-encoder",
    trust_remote_code=True,
    torch_dtype=torch.bfloat16,
).to(device)

audio, orig_freq = torchaudio.load(
    "https://www2.cs.uic.edu/~i101/SoundFiles/preamble10.wav"
)
audio = torchaudio.functional.resample(
    audio, orig_freq=orig_freq, new_freq=16_000
)  # must be a 16 kHz waveform array
# return_attention_mask=True for batching
audio_inputs = feature_extractor(audio, return_attention_mask=True, return_tensors="pt", device=device)
audio_inputs = audio_inputs.to(device)
with torch.autocast(dtype=torch.bfloat16, device_type="cuda"):
    audio_hidden_states = model(**audio_inputs)[0].detach().cpu().numpy().squeeze()


# instantiate a model for AudioClassification
model = AutoModelForAudioClassification.from_pretrained(
    "WueNLP/seamless-m4t-v2-large-speech-encoder",
    trust_remote_code=True,
    torch_dtype=torch.bfloat16,
    # SIB-Fleurs has 7 labels
    num_labels=7,
).to(device)
eng_Latn = load_dataset("wuenlp/sib-fleurs", "eng_Latn", split="train")
examples = [eng_Latn[i] for i in range(5)]
labels = torch.LongTensor([example["category"] for example in examples]).to(device)
batch = feature_extractor(
    # [0] indexing here since there typically are multiple utterances per instance, we just ignore those
    [example["audio"][0]["array"] for example in examples],
    sampling_rate=16000,
    device=device,
    return_attention_mask=True,
    return_tensors="pt",
).to(device)
batch["labels"] = labels
with torch.autocast(dtype=torch.bfloat16, device_type="cuda"):
    # outputs comprises loss & logits
    outputs = model(**batch)
