What is speech annotation?

Speech annotation is the process of labeling audio recordings of speech with relevant information, such as transcriptions, speaker identification, emotion, or linguistic features. This work is essential for training and improving speech recognition systems, natural language processing tools, and voice assistants. Annotators listen to audio clips and apply tags or notes according to specific guidelines, ensuring that machine learning models can accurately interpret spoken language. The quality and consistency of speech annotation directly impact the performance of AI systems that rely on understanding human speech.
