摘要： An apparatus for pre-processing a speech signal capable of improving the performance of speech signal processing by extracting the characteristics of noise that are distinguished from those of speech, and a method for extracting a speech end-point for the apparatus are provided. The apparatus includes a noise/speech determination unit for calculating noise information from at least one of an initial frame and a final frame of an input speech signal and determining if a current frame of the speech signal is a noise frame or a speech frame using the noise information, a hangover application unit for determining a predetermined number of frames transmitted after the current frame as consecutive speech frames when the current frame is the speech frame, and a speech information update unit for storing the speech frame and the consecutive speech frames. Noise information can be accurately calculated by using at least one of an initial noise frame and a final noise frame and continuously updating the noise information.

摘要： A receiver suppresses noise simultaneously using a noise suppressor and an automatic gain controller (AGC). The receiver divides a received signal into an audio period and a non-audio period, analyzes whether the noise characteristic of the non-audio period corresponds to a non-static noise or a static noise, and if the noise characteristic corresponds to the static noise, analyzes whether the static noise is caused by a network or a transmitter side terminal. In accordance with the analyzed noise characteristic, the noise suppressor firstly suppresses the noise by determining the noise suppressing intensity, and sends a signal, from which the noise has been firstly suppressed, to the AGC. The AGC secondly suppresses the noise included in the signal. In this case, the threshold value of the AGC is controlled in real time in accordance with the noise characteristic. Also, since the noise level is lowered by the first noise suppressing, the threshold value of the AGC can be set to a lower value, and thus a swing phenomenon and a radiotelegraph phenomenon can be reduced.

摘要： An apparatus and method are provided to output a received call with a volume adjusted to a reference level range in the etiquette call mode. In the method for providing the etiquette call mode of a mobile device, the apparatus determines whether the etiquette call mode is activated in a call mode. When the etiquette call mode is activated, the apparatus establishes a transmission gain to a given gain value and also establishes a reception gain to a specific gain value corresponding to a minimum receiving volume level. Then the apparatus amplifies a received call by means of the established reception gain, adjusts a volume of the amplified received call to a given reference level range, and outputs the adjusted received call through a speaker.
