Overview
This model is trained to recognize if there is any sort of background noise (be it a dog barking, street sounds, static, airplane noise, or anything other than the main speaker speaking) when there is a single speaker in the audio snippet. Fundamentally, it classifies an audio recording as noisy or not noisy and can detect background noise from both female and male speaker. We’ve tested this model on .wav audio, with 44100 sample rates, 16 bits per sample, and 2 channels with an average file size of 2MB.
Highlights
- Identify background noise - anything from a dog barking to street sounds to static - when there is a single speaker in the audio snippet

Amazon SageMaker model
An Amazon SageMaker model package is a pre-trained machine learning model ready to use without additional training. Use the model package to create a model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.
Version release notes
For CPU: We recommend using a ml.c5.xlarge (CPU) instance type. Our tests on these took 6.1 seconds prediction time for average payloads of 2.5 MB when invoked from a desktop.
