The VoxBlink2 Dataset

The VoxBlink2 dataset is a Large Scale speaker recognition dataset with 100K+ speakers obtained from YouTube platform. This repository provides guidelines to build the corpus and relative resources to reproduce the results in our article . For more introduction, please see cite. If you find this repository helpful to your research, don't forget to give us star🌟.

Resource

Let's start with obtaining the resource files and decompressing tar-files.

tar -zxvf spk_info.tar.gz
tar -zxvf vb2_meta.tar.gz 
tar -zxvf asr_res.tar.gz

Download

The following procedures show how to construct your VoxBlink2

Pre-requisites

1. Install ffmpeg:

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install ffmpeg

2. Install Python library:

pip install -r requirements.txt

3. Download videos

We provide two alternatives for you to download video or audio-only segments. We Also leverage multi-thread to facilate download process.

• For Audio-Visual

python downloader.py --base_dir ${BASE_DIR} --num_workers 4 --mode video

• For Audio-Only

python downloader.py --base_dir ${BASE_DIR} --num_workers 4 --mode audio

4. Crop Audio/Videos

• For Audio-Visual

python cropper_video.py --save_dir_audio ${SAVE_PATH_AUDIO} --save_dir_video ${SAVE_PATH_VIDEO} --timestamp_path meta --video_root=${BASE_DIR} --num_workers 4

• For Audio-Only

python cropper_audio.py --save_dir ${SAVE_PATH_AUDIO} --timestamp_path meta --audio_root=${BASE_DIR} --num_workers 4

FID Evaluation

We provide simple scripts of our face identification model, which is adopted in curating VoxBlink2. For more, please look at fid.

SV Evaluation

We provide simple scripts for model evaluation of ASV, just execute run_eval.sh in asv folder. For more, please look at asv.

Open-Set Speaker Identification Evaluation

We provide simple scripts for model evaluation of our proposed task: Open-Set Speaker-Identification(OSSI). just execute run_eval_ossi.sh in ossi folder. For more, please look at ossi.
