What is Audio Collection?

Audio collection is the first step in any machine learning project that depends on a spoken input. Conversational AI such as virtual assistants is an example of an application that requires a large amount of audio training data. Language and accent can create limitations for the effectiveness of solutions across environments and context. Adding diversity to your dataset will help overcome these challenges and help you pass your competition.
