Abstract: A system and method for processing audio text files includes a content repository storing audio text files. A text transformer linguistically analyzes the audio text files within a content of multiple lexicons to form edited text results and creates a reflection repository having reflection files therein corresponding to the audio text files from the edited text results. A search engine searches the reflection files and a user device displays a first reflection file from the reflection files or a first audio text file from the audio files in response to searching.

Abstract: A method performed in an audio decoder for reconstructing an original audio signal having a lowband portion and a highband portion is disclosed.

Abstract: A system and method for dynamically selecting speech recognition functionality on a client device for recognizing user speech inputs are disclosed. Such selection may be made based on speech recognition functionalities actually available on the client devices. The speech functionalities that may be dynamically selected may include, without limitation, speech recognition software and/or services, speech libraries, kernel drivers, speech recognition hardware, audio hardware, and/or any other speech functionality available on a client device. User speech inputs may be processed via the selected speech functionality for generating control commands in a virtual space. In some implementations, remote speech recognition support may be evoked when a client device does not have any speech recognition functionality on the client device.

Abstract: The disclosure provides a method and an apparatus for detecting a voice activity in an input audio signal composed of frames. A noise attribute of the input signal is determined based on a received frame of the input audio signal. A voice activity detection (VAD) parameter is derived based on the noise attribute of the input audio signal using an adaptive function. The derived VAD parameter is compared with a threshold value to provide a voice activity detection decision. The input audio signal is processed according to the voice activity detection decision.

Abstract: Mechanisms for identifying hidden meaning in a portion of natural language content are provided. A primary portion of natural language content is received and a secondary portion of natural language content is identified that references the natural language content. The secondary portion of natural language content is analyzed to identify indications of meaning directed to elements of the primary portion of natural language content. A probabilistic model is generated based on the secondary portion of natural language content modeling a probability of hidden meaning in the primary portion of natural language content. A hidden meaning statement data structure is generated for the primary portion of natural language content based on the probabilistic model.
