Introduction to Deep Learning for Sound Recognition

How do we recognize sound? How can we identify sound's many components and attributes? Given an audio recording (whether of musical, linguistic, or environmental sounds), how do we extract sonic features (acoustic or psychoacoustic: pitch, meter, emotion), classify types (genres, dialects, species), segment units (phonemes, notes, songs), and identify sources (speakers, singers, instruments, composers)? The general problem is complex, since visual and other sensory information is lacking. Sometimes recordings capture a single sound source: one instrument, speaker, or bird; others may gather multiple but coordinated sources: a musical ensemble, or a conversation.

More generally, in ethnomusicological, linguistic, or bioacoustic fieldwork, a recording encompasses a mix of uncoordinated sound sources, a total soundscape that mixes music, speech, and environmental sound in complex ways: music from multiple groups performing simultaneously, many speakers talking at once, or multiple environmental sound sources. Recordings layer "signals" (sounds of research interest) with “noise” (unwanted sound, including anthropogenic sounds of crowds, highways and factories, or natural sounds of animals, plants, rain, wind and thunder). Unlike the analogous challenges of recognizing components of visual “recordings” (photographs), our ability to recognize features of complex sound environments on audio recordings remains a rather mysterious process. More complex still are the psychoacoustic and cognitive processes by which we recognize emotions in particular sounds - particularly in speech and music.

In contrast to an earlier era of “small data” (largely the result of the limited capacity of expensive analog recorders), the advent of inexpensive, portable, digital recording devices of enormous capacity combined with a growing interest in sound across the humanities, social sciences, and sciences, now contribute vast collections of sound recordings, resulting in interest in sound within the realm of “big data.” To date, most of the sound collection data is not annotated and in all practicality, is therefore inaccessible for research.

Computational recognition of sound, its types, sources, attributes, and components--what may be called "machine audition" by analogy to the better-developed field of "machine vision"-- is crucial for a wide array of fields, including ethnomusicology, music studies, sound studies, linguistics (especially phonetics), media studies, library and information science, and bioacoustics, in order to enable indexing, searching, retrieval, and regression of audio information. While expert human listeners may be able to recognize certain complex sound environments with ease, the process is slow: they listen in real time, and they must be trained to hear sonic events contrapuntally.


This project explores the use of artificial intelligence to solve these problems. We apply supervised machine learning - primarily, deep learning neural networks trained on large datasets -- to develop sound recognition algorithms. Such algorithms enable labelling of digital repositories, and support interdisciplinary research on sound. More theoretically, this research helps develop machine audition and machine learning more broadly.
