Latest Patents

Petr's latest patents include a groundbreaking technique for privacy-sensitive speech model creation via the aggregation of multiple user models. The disclosed systems and methods aim to collect training data for updating acoustic models of speech recognition systems while ensuring user privacy. In one embodiment, the system locally creates adaptation data from raw audio data. This adaptation can include derived statistics and/or acoustic model update parameters. The processed statistics or updated acoustic model data can then be sent to a speech recognition server or third-party entity. Importantly, the data sent is devoid of any human-readable or machine-readable information that could enable the reconstruction of audio data. This ensures that personal or confidential information is not stored, allowing third-party servers to continually update speech models without retaining users' private utterances.
