Abstract: Systems and methods are provided for performing automated speech recognition. The systems and methods access a LM that includes a plurality of n-grams, each of the plurality of n-grams comprising a respective sequence of words and corresponding LM score and receive a list of words associated with a group classification, each word in the list of words being associated with a respective weight. The systems and method compute, based on the LM scores of the plurality of n-grams, a probability that a given word in the list of words associated with the group classification appears in an n-gram in the LM comprising an individual sequence of words and adds one or more new n-grams to the LM comprising one or more words in the list of words in combination with the individual sequence of words and associated with a particular LM score based on the computed probability.

Abstract: Systems and methods are provided for providing emotion-based text to speech. The systems and methods perform operations comprising accessing a text string; storing a plurality of embeddings associated with a plurality of speakers, a first embedding for a first speaker being associated with a first emotion and a second embedding for a second speaker of the plurality of speakers being associated with a second emotion; selecting the first speaker to speak one or more words of the text string; determining that the one or more words are associated with the second emotion; generating, based on the first embedding and the second embedding, a third embedding for the first speaker associated with the second emotion; and applying the third embedding and the text string to a vocoder to generate an audio stream comprising the one or more words being spoken by the first speaker with the second emotion.
