We’ll be setting up the sound event detection to detect the various instruments, voices, and anything else that will be heard in the audio track. For the sake of this walkthrough, we will be working with a prepared audio file, a liquid drum, and a bass audio track. Sometimes, you may already have files available via a cloud storage option. In the data import tab, upload the audio files you are working to label. Navigate to the next tab to begin to start your data import. In Label Studio, add a name and brief description of your project, and you’re off to the races. New to Label Studio or data labeling? Check out this blog post here to get started! Create a new Project. The latest release of Label Studio includes enhanced sound detection, new selection methods, advanced timeline zoom of up to x1500 times, and fine-tuned controls. These features are available in the Label Studio Enterprise edition or the open-source Label Studio Community edition. For the sake of this tutorial, you can use any data labeling tool you’d like, but we’ll be using Label Studio. As part of larger Natural Language Utterance (NLU) initiatives, audio annotations can detect dialects, context, and stress in transcription tools or even break down the parts of a song and provide better music recommendations.īefore diving head-first into a data annotation or labeling tool, let’s explore how to get started annotating audio data types and what you may need to know. In an increasingly multimedia world with a plethora of file formats, data annotation tools must be able to handle every single file format that you may work with on any given day.Īudio annotations can be used to develop speech recognition technology further. It’s essential that the tooling used by researchers, academics, enterprise data scientists, and machine learning professionals can keep up with the needs of the industry at large. The world of data labeling and annotation has come leaps and bounds recently. Special thanks to Brandon Martel and Nate Kartchner for your expertise and contributions to this post.
