摘要： A method of scaling polyphony can include identifying music data to be played (415), wherein the music data indicates instruments to be used and each instrument has an assigned priority. A measure of polyphony needed to play the music data can be compared with polyphony of a sound generating device (425). If the measure of polyphony exceeds the polyphony of the sound generating device, the music data can be played without using one or more instruments indicated by the music data according to the assigned priorities (440, 460).

摘要： Systems, an apparatus, and methods are provided for mitigating noise associated with an audio signal. A system (100) for mitigating noise associated with an audio signal includes an estimator module (108). The estimator module determines an estimated level of noise associated with the audio signal. The system also includes an expander module (110). The expander module causes an attenuation of the audio signal if a level of the audio signal is below a signal threshold. The expander module is adaptively tunable so that the attenuation caused (606) by the expander module is based upon the level of noise estimated (602) by the estimator module.

摘要： The invention concerns a method (300) and system (100) for improving voice quality of a vocoder (138, 158). The method includes the steps of monitoring (312) a pitch of a voice signal (400) at a transmitting unit (110); when the pitch of the voice signal reaches a predetermined threshold (840), shifting (326) the pitch of the voice signal to at least a portion of a predetermined range (810); transmitting (338) the pitch-shifted voice signal to a receiving unit (112); and at the receiving unit, reshifting (342) the pitch-shifted voice signal to a level that compensates the step of shifting the pitch of the voice signal at the transmitting unit.

摘要： A telephone (310) and a method for providing outbound audio when the telephone is operating in a speakerphone mode. A first data unit (350) including a first unit type identifier (360) can be received by the telephone. The first unit type identifier can be an indicator of a type of audio data contained in the first data unit. For instance, the first unit type identifier can indicate whether the audio data is music or non-music audio data. If the first unit type identifier has a first value, for example a value indicating that the audio data is music data, unmuted outbound audio reproduced from the first data unit can be provided and voice activity detection can be disabled. Additionally, inbound audio can be muted.
摘要翻译：一种电话（310）以及当电话在扬声器模式下工作时提供出站音频的方法。包括第一单元类型标识符（360）的第一数据单元（350）可以由电话接收。第一单元类型标识符可以是包含在第一数据单元中的音频数据的类型的指示符。例如，第一单元类型标识符可以指示音频数据是音乐还是非音乐音频数据。如果第一单元类型标识符具有第一值，例如表示音频数据是音乐数据的值，则可以提供从第一数据单元再现的未经调节的出站音频，并且可以禁止话音活动检测。此外，入站音频可以静音。

摘要： The invention concerns a system (100) and method (400) for operation of a voice activity detector (230). The system can include a speaker (105), a first microphone (110) and a second microphone (120) in which the first microphone and the second microphone can capture acoustic output from the speaker. The system can also include an adaptive module (220) in which the first microphone and the second microphone can provide signals to the adaptive module, and the adaptive module can provide an input to the voice activity detector. The adaptive module can receive a first input (242) from the first microphone and a second input (243) from the second microphone and can attempt to determine (430) a transformation between the first and second inputs for setting a configuration of the voice activity detector.

摘要： Methods and apparatus are provided for secure communication techniques in a communication system. The system can include a first device (10) which communicates with a second device (10’) over a channel. A security association can be established during a first session between the devices via an asymmetric key exchange (132). The security association comprises a Traffic Encryption Key (TEK) and a first state vector. The TEK comprises a shared, secret symmetric key. The security association is stored in each of the devices for use during a second session between the devices to expedite security association establishment during call set-up of the second session (428). The security association can be associated with the second device in the first device, and with the first device in the second device. An updated state vector can be generated at the first device. A second session can be established between the first device and the second device by using the TEKs from the first session and the updated state vector. The security association can be used to encrypt (4) voice packets being sent from the first device to the second device. The security association and updated state vector can then be used to decrypt (6) the encrypted voice packets received by the second device from the first device.
