Sound Analysis

Overview

Identify specific sounds in your app, such as laughter or applause, by creating an SNClassifySoundRequest to analyze an audio file or stream. Sound requests can identify over 300 sounds. Alternatively, you identify a custom set of sounds by providing the sound request with a custom Core ML model. You train a custom sound classification model by creating an MLSoundClassifier with audio data in Create ML.
