Is someone talking? TalkNet: Audio-visual active speaker detection Model

This repository contains the code for our ACM MM 2021 paper (oral), TalkNet, an active speaker detection model to detect 'whether the face in the screen is speaking or not?'. [Paper] [Video_English] [Video_Chinese].

• Awesome ASD: Papers about active speaker detection in last years.

• TalkNet in AVA-Activespeaker dataset: The code to preprocess the AVA-ActiveSpeaker dataset, train TalkNet in AVA train set and evaluate it in AVA val/test set.

• TalkNet in TalkSet and Columbia ASD dataset: The code to generate TalkSet, an ASD dataset in the wild, based on VoxCeleb2 and LRS3, train TalkNet in TalkSet and evaluate it in Columnbia ASD dataset.

• An ASD Demo with pretrained TalkNet model: An end-to-end script to detect and mark the speaking face by the pretrained TalkNet model.

Dependencies

Start from building the environment

conda create -n TalkNet python=3.7.9 anaconda
conda activate TalkNet
pip install -r requirement.txt

Start from the existing environment

pip install -r requirement.txt

TalkNet in AVA-Activespeaker dataset

Data preparation

The following script can be used to download and prepare the AVA dataset for training.

python trainTalkNet.py --dataPathAVA AVADataPath --download 

AVADataPath is the folder you want to save the AVA dataset and its preprocessing outputs, the details can be found in here . Please read them carefully.

Training

Then you can train TalkNet in AVA end-to-end by using:

python trainTalkNet.py --dataPathAVA AVADataPath

exps/exps1/score.txt: output score file, exps/exp1/model/model_00xx.model: trained model, exps/exps1/val_res.csv: prediction for val set.

Pretrained model

Our pretrained model performs mAP: 92.3 in validation set, you can check it by using:

python trainTalkNet.py --dataPathAVA AVADataPath --evaluation

The pretrained model will automaticly be downloaded into TalkNet_ASD/pretrain_AVA.model. It performs mAP: 90.8 in the testing set.

TalkNet in TalkSet and Columbia ASD dataset

Data preparation

We find that it is challenge to apply the model we trained in AVA for the videos not in AVA (Reason is here, Q3.1). So we build TalkSet, an active speaker detection dataset in the wild, based on VoxCeleb2 and LRS3.

We do not plan to upload this dataset since we just modify it, instead of building it. In TalkSet folder we provide these .txt files to describe which files we used to generate the TalkSet and their ASD labels. You can generate this TalkSet if you are interested to train an ASD model in the wild.

Also, we have provided our pretrained TalkNet model in TalkSet. You can evaluate it in Columbia ASD dataset or other raw videos in the wild.

Usage

A pretrain model in TalkSet will be download into TalkNet_ASD/pretrain_TalkSet.model when using the following script:

python demoTalkNet.py --evalCol --colSavePath colDataPath

Also, Columnbia ASD dataset and the labels will be downloaded into colDataPath. Finally you can get the following F1 result.

(This result is different from that in our paper because we train the model again, while the avg. F1 is very similar)

An ASD Demo with pretrained TalkNet model

Data preparation

We build an end-to-end script to detect and extract the active speaker from the raw video by our pretrain model in TalkSet.

You can put the raw video (.mp4 and .avi are both fine) into the demo folder, such as 001.mp4.

Usage

python demoTalkNet.py --videoName 001

A pretrain model in TalkSet will be downloaded into TalkNet_ASD/pretrain_TalkSet.model. The structure of the output reults can be found in here.

You can get the output video demo/001/pyavi/video_out.avi, which has marked the active speaker by green box and non-active speaker by red box.

If you want to evaluate by using cpu only, you can modify demoTalkNet.py and talkNet.py file: modify all cuda into cpu. Then replace line 83 in talkNet.py into loadedState = torch.load(path,map_location=torch.device('cpu'))

I have summaried some potential FAQs. You can also check the issues in Github for other questions that I have answered.

This is my first open-source work, please let me know if I can future improve in this repositories or there is anything wrong in our work. Thanks for your support!

Acknowledge

We study many useful projects in our codeing process, which includes:

The structure of the project layout and the audio encoder is learnt from this repository.

Demo for visulization is modified from this repository.

AVA data download code is learnt from this repository.

The model for the visual frontend is learnt from this repository.

Thanks for these authors to open source their code!
