Latest Patents

One of Haochen Sun's latest patents is a system and apparatus for real-time speech enhancement in noisy environments. This innovative system performs speech enhancement of audio data in real-time by suppressing noise components while preserving speech components. The system includes an in-ear module and a separate signal processing module that is wirelessly communicatively coupled to the in-ear module. It utilizes non-negative matrix factorization (NMF) dictionaries capable of identifying frequency band components associated with speech and noise. These dictionaries are trained using voice and noise samples, allowing the system to produce an NMF representation of the speech data. This representation is then applied using a dynamic mask to suppress noise components and enhance the clarity of speech data.
