    Abstract: 적어도초광대역 (SWB) 대역폭들까지스피치신호들및 음악신호들양자의핸들링을향상시키기위해적응적잡음억제를수행하는기법들이기술된다. 그기법들은오디오데이터가캡쳐되는콘텍스트또는환경을식별하는것, 및콘텍스트에기초하여대역폭압축 (예를들어, 인코딩) 이전에오디오데이터에적용되는잡음억제의레벨을적응적으로변경하는것을포함한다. 유효한스피치콘텍스트의경우, 오디오프리프로세서는스피치신호들에서 (음악을포함하는) 잡음을억제하기위해상대적으로공격적인잡음억제의제 1 레벨을설정할수도있다. 유효한음악콘텍스트의경우, 오디오프리프로세서는음악신호들을왜곡되지않은채 남겨두기위해덜 공격적인잡음억제의제 2 레벨을설정할수도있다. 이러한식으로, 송신기측무선통신디바이스의보코더는최소의왜곡들로스피치및 음악신호들양자를적절하게인코딩할수도있다.

    Abstract: A device includes a receiver, a buffer, and an analyzer. The receiver is configured to receive packets that correspond to at least a subset of a sequence of packets and that include error correction data. The error correction data of a first packet of the packets includes a partial copy of a second packet. The buffer is configured to store the packets. The analyzer is configured to determine whether a first particular packet of the sequence is missing from the buffer, to determine whether a partial copy of the first particular packet is stored in the buffer as error correction data in a second particular packet, to update a value based at least in part on whether the first particular packet is missing from the buffer and the partial copy of the first particular packet is stored in the buffer, and to adjust an error recovery parameter based at least in part on the value.

    Abstract: A method for determining an interpolation factor set by an electronic device is described. The method includes determining a value based on a current frame property and a previous frame property. The method also includes determining whether the value is outside of a range. The method further includes determining an interpolation factor set based on the value and a prediction mode indicator if the value is outside of the range. The method additionally includes synthesizing a speech signal.
