Task: Question Answering
Input (English): As the first step, we build three baseline LID systems, one based on the i-vector model, and the other two based on LSTM-RNN, using the speech data of two languages from Babel: Assamese and Georgian (AG). The two RNN LID baselines are: a standard RNN LID system (AG-RNN-LID) that discriminates between the two languages in its output, and a multi-task system (AG-RNN-MLT) that was trained to discriminate between the two languages as well as the phones. 
 Question: Which is the baseline model?
Output (English): The three baseline models are the i-vector model, a standard RNN LID system and a multi-task RNN LID system.
