Latest Patents

Dusan Macho’s most recent patents reflect his dedication to improving speech recognition systems. The first patent, titled "Noise Reduced Speech Recognition Parameters," introduces a voice sample characterization front-end designed for use in a distributed speech recognition context. This innovative approach involves splitting a digitized voice sample into low-frequency and high-frequency paths, allowing for a thorough noise reduction capability. The low-frequency path effectively reduces unwanted noise, thereby assisting the high-frequency path in de-noising without demanding extensive resources.

The second patent, "Methods and Apparatus for Reducing Noise Associated with an Electrical Speech Signal," focuses on enhancing the signal-to-noise ratio of speech signals. This invention identifies local energy maximums that correspond to speech pitch periods, using the natural characteristics of human speech to enhance clarity. By increasing energy at the beginning of pitch periods and reducing it at the end, this method preserves the overall energy while improving the intelligibility of spoken words.
