Latest Patents

One of Rainer Martin's latest patents is titled "Speech enhancement with gain limitations based on speech activity." This invention presents an apparatus and method for data processing that improves the estimation of spectral parameters of speech data while reducing algorithmic delay in data coding operations. The method enhances data by adaptively adjusting a gain function based on whether the data contains speech and noise or noise only. A critical aspect of this invention is the determination of whether the speech signal represents articulated speech or a speech pause, which influences the gain applied to the speech signal. The gain's lower limit is constrained during periods of speech activity compared to speech pauses, ensuring optimal enhancement. Additionally, the invention reduces delay by extracting coding parameters using incompletely processed data, which is formed through a specific overlap-add process.
