VGGish in Keras.

Project description

VGGish: A VGG-like audio classification model

This repository provides a VGGish model, implemented in Keras with tensorflow backend (since tf.slim is deprecated, I think we should have an up-to-date interface). This repository is developed based on the model for AudioSet. For more details, please visit the slim version.


pip install vggish-keras

Weights will be automatically downloaded when installing via pip.

Currently - this relies on a pending change to pumpp in To get those changes, you need

pip install git+


import librosa
import numpy as np
import vggish_keras as vgk

# define the model
pump = vgk.get_pump()
model = vgk.VGGish(pump)

# transform audio into VGGish embeddings without fc layers
X = pump.transform(librosa.util.example_audio_file())[vgk.params.PUMP_INPUT]
X = np.concatenate([X]*5)
Z = model.predict(X)

# calculate timestamps
op = pump['mel']
ts = np.arange(len(Z)) / * op.hop_length
assert Z.shape == (5, 512)



  • add fully connected layers
  • add PCA postprocessing (needs fully connected layers and to add PCA params to model)
  • currently, parameters (sample rate, hop size, etc) can be changed globally via vgk.params - I'd like to allow for parameter overrides to be passed to vgk.VGGish
