Far-Field Speaker Verification Challenge
Introduction
Welcome to the Interspeech 2020 Far-Field Speaker Verification Challenge (FFSVC 2020).
Speaker verification is a key technology in speech processing and biometric authentication, which has broad impact on our daily lives, e.g. security, customer service, mobile devices, smart speakers. Recently, speech based human computer interaction has become more and more popular in far-field smart home and smart city applications, e.g. mobile devices, smart speakers, smart TVs, automobiles. Due to the usage of deep learning methods, the performances of speaker verification in telephone channel and close-talking microphone channel have been enhanced dramatically. However, there are still some open research questions that can be further explored for speaker verification in the far-field and complex environments, including but not limited to

The FFSVC20 Challenge Dataset Description
This FFSVC20 challenge database is provided by AISHELL , which has released multiple open source databases, namely AISHELL 1 ,
This FFSVC20 challenge database is part of the AISHELL Distributed Microphone Arrays in Smart Home (DMASH) Database. The recording devices include one close-talking microphone (48kHz, 16 bit), one cellphone (48kHz, 16 bit) at 25cm distance and multiple circular microphone arrays (16kHz, 16bit, 4 out of 16 microphones, 5cm radius). The language is Chinese Mandarin. Text content include 'ni hao, mi ya' as text dependent utterances as well as other text independent ones.
The data collection setup is shown in Fig 1.Red arrow points to channel 0 of microphone arrays.

Each speaker visit 3 times with 7-15 days gap.

• Far-field text-dependent speaker verification for wake up control
• Far-field text-independent speaker verification with complex environments
• Far-field speaker verification with cross-channel enrollment and test
• Far-field speaker verification with single multi-channel microphone array
• Far-field speaker verification with multiple distributed microphone arrays
• Far-field speaker verification with front-end speech enhancement methods
• Far-field speaker verification with end-to-end modeling using data augmentation
• Far-field speaker verification with front-end and back-end joint modeling
• Far-field speaker verification with transfer learning and domain adaptation
The FFSVC 2020 challenge is designed to boost the speaker verification research with special focus on far-field distributed microphone arrays under noisy conditions in real scenes. The objectives of this challenge are to: 1) benchmark the current speech verification technology under this challenging condition, 2) promote the development of new ideas and technologies in speaker verification, 3) provide an open, free, and large scale speech database to the community that exhibits the far-field characteristics in real scenes.
The challenge have three tasks in different scenes.
•Task 1: Far-Field Text-Dependent Speaker Verification from single microphone array
•Task 2: Far-Field Text-Independent Speaker Verification from single microphone array
•Task 3: Far-Field Text-Dependent Speaker Verification from distributed microphone arrays
All three tasks follow the cross-channel setup. The recordings of close-talking cellphone will be selected as enrollment and the recordings of far-field microphone array will be used for test.
Each registered team could participate in any one or two or all three tasks.

The HIMIA dataset description
The HI-MIA database includes two sub databases, which are the AISHELL- wakeup1 with 254 speakers and the AISHELL-2019B-eval with 86 speakers. The HIMIA_FFSVC2020_overlap.txtcontains the list of speakers that overlap between the HIMIA dataset and our challenge data.
The content of utterances is “ni hao, mi ya”(“你 好, 米 雅”) ’ in Mandarin. The HI-MIA database served as the benchmark data for AISHELL Speaker Verification Challenge 2019. Click here to download the HI-MIA dataset and dataset description.
Since the original audio name format of the HI-MIA database is a little bit confusing, we provide a new version of the label files (train_rename.scp and dev_rename.scp for Hi-MIA). Click here to download.
Since the audio files in the HI-MIA test set is not strictly synchronized , different channels of the same device may have slightly different audio lengths. The original synchronized test data can be downloaded here For the training and development set of HI-MIA, all channels from each microphone array are synchronized.
Data Download
The FFSVC20 challenge is completed, please email to aishell.foundation@gmail.com with subject “Apply for the FFSVC2020 Challenge data”if you want to download the challenge data. The whole challenge data includes the training/development/evaluation data and dev/eval trial files with keys.
