The *larger clap music and speech* model is an enhanced version of CLAP, designed to understand and connect language to audio, much like CLIP does for images. Specifically trained on music and speech data, it excels in tasks such as zero-shot audio classification or extracting audio and text features. Its core capabilities include analyzing diverse audio content and generating precise matches between textual descriptions and sound clips. The model stands out for its versatility, enabling the identification of sounds or musical genres from simple text instructions without requiring specific training data. It proves particularly useful for applications like audio search, automatic transcription, or organizing music libraries.
CLAP is to audio what CLIP is to image. This is an improved CLAP checkpoint, specifically trained on music and speech.
CLAP (Contrastive Language-Audio Pretraining) is a neural network trained on a variety of (audio, text) pairs. It can be instructed in to predict the most relevant text snippet, given an audio, without directly optimizing for the task. The CLAP model uses a SWINTransformer to get audio features from a log-Mel spectrogram input, and a RoBERTa model to get text features. Both the text and audio features are then projected to a latent space with identical dimension. The dot product between the projected audio and text features is then used as a similar score.
You can use this model for zero shot audio classification or extracting audio and/or textual features.
pipelinefrom datasets import load_dataset
from transformers import pipeline
dataset = load_dataset("ashraq/esc50")
audio = dataset["train"]["audio"][-1]["array"]
audio_classifier = pipeline(task="zero-shot-audio-classification", model="laion/larger_clap_music_and_speech")
output = audio_classifier(audio, candidate_labels=["Sound of a dog", "Sound of vaccum cleaner"])
print(output)
>>> [{"score": 0.999, "label": "Sound of a dog"}, {"score": 0.001, "label": "Sound of vaccum cleaner"}]
You can also get the audio and text embeddings using ClapModel

processor = ClapProcessor.from_pretrained("laion/larger_clap_music_and_speech")
inputs = processor(audios=audio_sample["audio"]["array"], return_tensors="pt")
audio_embed = model.get_audio_features(**inputs)
