General View

We leveraged 3D convolutional architecture for creating the speaker model in order to simultaneously capturing the speech-related and temporal information from the speakers' utterances.

Speaker Verification Protocol(SVP)

In this work, a 3D Convolutional Neural Network (3D-CNN) architecture has been utilized for text-independent speaker verification in three phases.

1. At the development phase, a CNN is trained to classify speakers at the utterance-level.

2. In the enrollment stage, the trained network is utilized to directly create a speaker model for each speaker based on the extracted features.

3. Finally, in the evaluation phase, the extracted features from the test utterance will be compared to the stored speaker model to verify the claimed identity.

The aforementioned three phases are usually considered as the SV protocol. One of the main challenges is the creation of the speaker models. Previously-reported approaches create speaker models based on averaging the extracted features from utterances of the speaker, which is known as the d-vector system.

How to leverage 3D Convolutional Neural Networks?

In our paper, we propose the implementation of 3D-CNNs for direct speaker model creation in which, for both development and enrollment phases, an identical number of speaker utterances is fed to the network for representing the spoken utterances and creation of the speaker model. This leads to simultaneously capturing the speaker-related information and building a more robust system to cope with within-speaker variation. We demonstrate that the proposed method significantly outperforms the d-vector verification system.

Code Implementation

The input pipeline must be provided by the user. Please refer to ``code/0-input/input_feature.py`` for having an idea about how the input pipeline works.

Input Pipeline for this work

The MFCC features can be used as the data representation of the spoken utterances at the frame level. However, a drawback is their non-local characteristics due to the last DCT 1 operation for generating MFCCs. This operation disturbs the locality property and is in contrast with the local characteristics of the convolutional operations. The employed approach in this work is to use the log-energies, which we call MFECs. The extraction of MFECs is similar to MFCCs by discarding the DCT operation. The temporal features are overlapping 20ms windows with the stride of 10ms, which are used for the generation of spectrum features. From a 0.8- second sound sample, 80 temporal feature sets (each forms a 40 MFEC features) can be obtained which form the input speech feature map. Each input feature map has the dimen- sionality of ζ × 80 × 40 which is formed from 80 input frames and their corresponding spectral features, where ζ is the number of utterances used in modeling the speaker during the development and enrollment stages.

The speech features have been extracted using [SpeechPy] package.

Implementation of 3D Convolutional Operation

The Slim high-level API made our life very easy. The following script has been used for our implementation:

net = slim.conv2d(inputs, 16, [3, 1, 5], stride=[1, 1, 1], scope='conv11')
net = PReLU(net, 'conv11_activation')
net = slim.conv2d(net, 16, [3, 9, 1], stride=[1, 2, 1], scope='conv12')
net = PReLU(net, 'conv12_activation')
net = tf.nn.max_pool3d(net, strides=[1, 1, 1, 2, 1], ksize=[1, 1, 1, 2, 1], padding='VALID', name='pool1')

############ Conv-2 ###############
############ Conv-1 ###############
net = slim.conv2d(net, 32, [3, 1, 4], stride=[1, 1, 1], scope='conv21')
net = PReLU(net, 'conv21_activation')
net = slim.conv2d(net, 32, [3, 8, 1], stride=[1, 2, 1], scope='conv22')
net = PReLU(net, 'conv22_activation')
net = tf.nn.max_pool3d(net, strides=[1, 1, 1, 2, 1], ksize=[1, 1, 1, 2, 1], padding='VALID', name='pool2')

############ Conv-3 ###############
############ Conv-1 ###############
net = slim.conv2d(net, 64, [3, 1, 3], stride=[1, 1, 1], scope='conv31')
net = PReLU(net, 'conv31_activation')
net = slim.conv2d(net, 64, [3, 7, 1], stride=[1, 1, 1], scope='conv32')
net = PReLU(net, 'conv32_activation')
# net = slim.max_pool2d(net, [1, 1], stride=[4, 1], scope='pool1')

############ Conv-4 ###############
net = slim.conv2d(net, 128, [3, 1, 3], stride=[1, 1, 1], scope='conv41')
net = PReLU(net, 'conv41_activation')
net = slim.conv2d(net, 128, [3, 7, 1], stride=[1, 1, 1], scope='conv42')
net = PReLU(net, 'conv42_activation')
# net = slim.max_pool2d(net, [1, 1], stride=[4, 1], scope='pool1')

############ Conv-5 ###############
net = slim.conv2d(net, 128, [4, 3, 3], stride=[1, 1, 1], normalizer_fn=None, scope='conv51')
net = PReLU(net, 'conv51_activation')

# net = slim.conv2d(net, 256, [1, 1], stride=[1, 1], scope='conv52')
# net = PReLU(net, 'conv52_activation')

# Last layer which is the logits for classes
logits = tf.contrib.layers.conv2d(net, num_classes, [1, 1, 1], activation_fn=None, scope='fc')

As it can be seen, slim.conv2d has been used. However, simply by using 3D kernels as [k_x, k_y, k_z] and stride=[a, b, c] it can be turned into a 3D-conv operation. The base of the slim.conv2d is tf.contrib.layers.conv2d. Please refer to official Documentation for further details.

Problem with evaluation.

Hi @astorfi ,thank for your great work, i also use all the same settings but use hdf5 to store training data instead of Audio Dataset. However, my evaluation result is low, EER is up to 40%. I think there is something wrong with my work. Do you have any idea to fix this? I use VoxCeleb dataset for background model and only use 1 sample per speaker. 50 people for enrollment, 50 for un-enrollment (reject). 4 samples for evaluation.

Thank for your help.

Regarding input data

Hi @astorfi I have gone through your code. While extracting mfcc features for sample audio file it contains shape (420,40) here, 420 is number of frames and 40 is number of features.But In sample data of your code youre applying mfec feature file contains shape (3209,40,3). As per my understanding 3209 is Number of Frames,40 is Number of Features,3 Is number of Channels. I didn't understand the number of channels usage.can you please suggest how to create Feature_mfec.npy file in your format.

How to generate data

Hello,

I have a dataset of voices. I want to generate development and enrollment hdf5 file. The input_feature.py file seams to generate development files (nx80x40x20). How can I generate the enrollment file?

Retrain on new and own dataset

Hi,

First, that is a great job and ver well done :) Now I am trying to use your source code and maybe contribute to it, I am working on a speaker recognition problem to detect if a teacher tutorial is recorded by his voic. I have about 10 hours of historical recordings for 6 teachers. First I used the speechpy to get 3d npy from wav files and used your create_development.py to create the hdf5 files for train and eval. Is that correct? Specially I got 13 instead of 40 regarding the features vector length in the npy files! I ran the run.bash file and it gave me also error saying something like that: ValueError: Negative dimension size caused by subtracting 2 from 1 for 'MaxPool_7' (op: 'MaxPool') with input shapes: [?,1,112,128].

loss = 0,train acc = 0

Hi astorfi, I'm trying to use your code to train a model with 31 labels, 60 samples for each label. However, when i use train_softmax.py, last minibatches return loss = 0 while train acc = 0. Do you have any idea to fix it?

Thank you.

shape mismatch problem in input_feature.py

Hello! We are trying to make our own input pipeline. However, when we follow the getitem method in Audioset (with the setting that cube_shape is (20,80,40)), there is a shape mismatch when the model tries to feed data for batch_speech (placeholder with the shape of (20,80,.40,1)).

After carefully review the code in train_softmax.py, we find that the input shape will conflict with the transpose operation in following code:

speech_train = np.transpose(speech_train[None, :, :, :, :], axes=(1, 4, 2, 3, 0))

What is the solution? Could you give us any help?

.wav inputs specifics

Hi guys, I have a question regarding the input wav files used for training. What are the audio format specifications? I used voxceleb ( http://www.robots.ox.ac.uk/~vgg/data/voxceleb/ ) as dataset, but it is giving me some troubles. Do you know about any other usable dataset?

Thank you ;)

　All Dependency of This Project

Hi, astorfi First of all, thanks for your contribution to this project. I have some doubts: 　１. Is it necessary to isolate all dependencies of this project so that all human cloning repository 　　do not need to install various dependencies separately？ 2. Is it necessary to further describe the operation steps of the demo　to facilitate others to repair 　　and match their own needs？ Looking forward to your early reply and best wish！ Yours, Vickey

Does anyone know the EER of this repo?

Hi. I am looking for some speaker verification repo that gives decent EER. I have tried some open source speaker verifications but I haven't been able to find anything that gives below 10 % EER with VoxCeleb1 DB. The speaker verification models availablie online are usually trained with smaller and cleaner DBs and tend not to give reasonable EER on VoxCeleb1. Can anybody please tell me if there is any decent one? I would really appreciate it :D
