AISHELL-1: An Open-Source Mandarin Speech Corpus and A Speech Recognition Baseline

, 2017
An open-source Mandarin speech corpus called AISHELL-1 is released. It is by far the largest corpus which is suitable for conducting the speech recognition research and building speech recognition systems for Mandarin.

Deep Contextualized Acoustic Representations For Semi-Supervised Speech Recognition

, 2020
We propose a novel approach to semi-supervised automatic speech recognition (ASR). We first exploit a large amount of unlabeled audio data via representation learning, where we reconstruct a temporal slice of filterbank features from past and future ...

Universal Adversarial Perturbations for Speech Recognition Systems [PDF]

, 2019
In this work, we demonstrate the existence of universal adversarial audio perturbations that cause mis-transcription of audio signals by automatic speech recognition (ASR) systems. We propose an algorithm to find a single quasi-imperceptible perturbation,

Anti-social behavior detection in audio-visual surveillance systems [PDF]

, 2009
In this paper we propose a general purpose framework for detection of unusual events. The proposed system is based on the unsupervised method for unusual scene detection in web{cam images that was introduced in [1].

Automatic speech recognition and the transcription of indistinct forensic audio: how do the new generation of systems fare?

Frontiers in Communication
This study provides an update on an earlier study in the “Capturing Talk” research topic, which aimed to demonstrate how automatic speech recognition (ASR) systems work with indistinct forensic-like audio, in comparison with good-quality audio.

Exploring the technological dimension of Autonomous sensory meridian response-induced physiological responses [PDF]

PeerJ
Background In recent years, the scientific community has been captivated by the intriguing Autonomous sensory meridian response (ASMR), a unique phenomenon characterized by tingling sensations originating from the scalp and propagating down the spine ...

Local Control of Audio Environment: A Review of Methods and Applications

Technologies, 2014
The concept of a local audio environment is to have sound playback locally restricted such that, ideally, adjacent regions of an indoor or outdoor space could exhibit their own individual audio content without interfering with each other.
