Latest Patents

One of McAllaster's latest patents is titled "Low-latency multi-speaker speech recognition." This invention provides systems and processes for operating an intelligent automated assistant. The method involves receiving mixed speech data that represents utterances from a target speaker and other interfering audio sources. It includes obtaining a target speaker representation that captures the speech characteristics of the target speaker. Using a learning network, the method determines probability distributions of phonetic elements directly from the mixed speech data. The output includes generating text corresponding to the target speaker's utterances and providing a response based on that text.

Another significant patent is "Inverse text normalization for automatic speech recognition." This invention outlines techniques for inverse text normalization. It begins with receiving speech input and generating a spoken-form text representation. A feature representation is determined for this spoken-form text, leading to a sequence of labels that specify various edit operations to be performed on the token sequence. Ultimately, a written-form text representation is generated, which is then used to perform tasks responsive to the speech input.
