Speech recognition in digital assistants such as Google Assistant can
potentially benefit from the use of conversational context consisting of user
queries and responses from the agent. We explore the use of recurrent,
Long Short-Term Memory (LSTM), neural language models (LMs) to model the conversations
in a digital assistant. Our proposed methods effectively capture the context of
previous utterances in a conversation without modifying the underlying LSTM
architecture. We demonstrate a 4% relative improvement in recognition performance
on Google Assistant queries when using the LSTM LMs to rescore recognition lattices.
