Noise Cancellation

Noise cancellation technology of single-Microphone solution is used for reducing the external hindrances and background noises in speech signal. NC can be used as for the selection of speech signal, so and for the selection of background noises. NC is recommended to use in case of an amount of hindrances is unknown beforehand or it is impossible in the evident type to select "point" source of hindrances (absent-minded hindrance). Filter noise cancellation is automatically adapted under all types of surrounding hindrances and selects a refined of speech signal. Algorithms for high quality modification of speech signal are useful for applications such as: - Wireless telephony systems; - Internet telephony and PC telephony ; - Voice messaging services (Voice mail); - Mobile phones with or without a free operation system; - Call service centers.
