AI Voice-Over refers to the use of artificial intelligence (AI) or machine learning (ML) technologies to generate a human-like voice that speaks text in natural language. It allows users to create audio content efficiently without the need for a human narrator. The technology is widely used in the film, TV and advertising industries to create, for example, documentaries, advertisements and news broadcasts. There are different types of AI voice-over technologies, from simple text-to-speech applications to more advanced systems that are able to recognise and reproduce emotions and accents in speech.
