This article describes an audio signal processing algorithm to detect water sounds, built in the context of a larger system aiming to monitor daily activities of elderly people. While previous proposals for water sound recognition relied on classical machine learning and generic audio features to characterize water sounds as a flow texture, we describe here a recognition system based on a physical model of air bubble acoustics. This system is able to recognize a wide variety of water sounds and…

Detection of Acoustic Events by using MFCC and Spectro-Temporal Gabor Filterbank Features
TLDR
This work uses the DCASE dataset, published in an international IEEE AASP challenge for Acoustic Event Detection which includes the "office live" recordings which were prepared in an office environment and proposes to use the Gabor filterbank in addition to MFCCs coefficients to analyze the feature.
Acoustic scene classification based on generative model of acoustic spatial words for distributed microphone array
TLDR
Experimental results show that the proposed approach achieves more effective performance than the conventional acoustic scene classification approach not utilizing a combination of the spatial information of multiple sound events.
Acoustic Scene Classification: Classifying environments from the sounds they produce
TLDR
An account of the state of the art in acoustic scene classification (ASC), the task of classifying environments from the sounds they produce, and a range of different algorithms submitted for a data challenge to provide a general and fair benchmark for ASC techniques.
Proceedings of the Detection and Classification of Acoustic Scenes and Events 2019 Workshop (DCASE2019)
TLDR
The proposed SED system is compared against the state of the art mono channel method on the development subset of TUT sound events detection 2016 database and the usage of spatial and harmonic features are shown to improve the performance of SED.
A Physiologically Motivated Approach to the Classification of Natural Sounds using High Order Sound Statistics
TLDR
The hypothesis is that two sound statistics, intensity and contrast, will be sufficient to classify broad categories of sounds using a naïve Bayesian classifier and that the hierarchical approach to classification is appropriate for many, but not all, types of sounds.
Acoustic Scene Classification
TLDR
An account of the state-of-the-art in acoustic scene classification (ASC), the task of classifying environments from the sounds they produce, and a range of different algorithms submitted for a data challenge to provide a general and fair benchmark for ASC techniques.
Joint Analysis of Acoustic Events and Scenes Based on Multitask Learning
TLDR
Experimental results obtained indicate that the proposed multitask learning for joint analysis of acoustic events and scenes improves the performance of acoustic event detection by 10.66 percentage points in terms of the F-score, compared with a conventional method based on a convolutional recurrent neural network.
Water Sound Recognition Based on Support Vector Machine
TLDR
A sound signal processing method to identify the water sound and link it with stream-flow measurements and the result of recognition is superior to other classification models.
BROWSING SOUNDSCAPES
TLDR
SamoCharts provide a compact and efficient representation of sounds and soundscapes, which can be used in different kinds of applications, and are inspired by TMcharts, but can be computed without a human annotation.
Automatic acoustic recognition of shad splashing using a smartphone
TLDR
In order to automatically estimate the number of migrating shad in rivers, an acoustic signal analysis method is proposed, based on short-term spectral analysis, combined with a Gaussian mixture model.
