Latest Patents

Ertem holds a patent for a "Method of noise reduction for speech codecs." This invention provides an improved noise reduction algorithm and a voice activity detector designed for use in voice communication systems. The voice activity detector enables a reliable estimate of noise and enhances noise reduction capabilities. The algorithm and detector can be implemented together in an encoder or applied independently in speech coding applications. The voice activity detector utilizes line spectral frequencies and enhanced input speech that has undergone noise reduction to generate a voice activity flag. The noise reduction algorithm employs a smooth gain function based on a smoothed noise spectral estimate and smoothed input noisy speech spectra. This gain function is adapted over frequency and time according to the estimated signal-to-noise ratio, resulting in enhanced spectral amplitude and reduced noise in the speech signal. Additionally, the method incorporates critical frequency bands that correspond to the human auditory system, improving the overall perception of decoded speech.
