What is Audio Annotation?

Audio annotation is the process of labeling sound recordings to extract meaningful information such as spoken words, speaker identity, emotions, background noise, events, or actions. Annotated audio becomes the training data that powers applications like speech-to-text engines, voice assistants, call analytics, language understanding systems, and acoustic scene classifiers.
