Latest Patents

One of Satoh's key inventions is a speech detection apparatus that is not affected by input energy or background noise. This innovative device is capable of reliably detecting speech segments in audio signals, regardless of the levels of input audio signals and background noises. The apparatus calculates parameters of input audio signals frame by frame and compares them with a threshold to classify each frame as either a speech segment or a noise segment. Parameters from frames identified as noise are stored in a buffer, allowing the threshold to be updated based on this stored data. Additionally, the apparatus may utilize transformed parameters that emphasize the differences between speech and noise, constructing noise standard patterns from pre-estimated noise segments. This invention has the potential to enhance communication technologies significantly.
