摘要： Captured vocals may be automatically transformed using advanced digital signal processing techniques that provide captivating applications, and even purpose-built devices, in which mere novice user-musicians may generate, audibly render and share musical performances. In some cases, the automated transformations allow spoken vocals to be segmented, arranged, temporally aligned with a target rhythm, meter or accompanying backing tracks and pitch corrected in accord with a score or note sequence. Speech-to-song music applications are one such example. In some cases, spoken vocals may be transformed in accord with musical genres such as rap using automated segmentation and temporal alignment techniques, often without pitch correction. Such applications, which may employ different signal processing and different automated transformations, may nonetheless be understood as speech-to-rap variations on the theme.

摘要： A method and apparatus for splitting the audio of media content into separate content files without introducing boundary artifacts is described. An exemplary method of streaming media content including audio and video involves a computing system receiving a plurality of content files and staging the encoded portion of the audio of the content files for presentation as a continuous stream. Each of the content files comprises an encoded portion of the video encoded according to a frame rate and having a fixed-time duration and an encoded portion of the audio encoded according to a codec-enforced frame size and having a plurality of full audio frames having the codec-enforced frame size. A duration of the encoded portion of the audio of one or more of the content files is greater than or less than the fixed-time duration.

摘要： According to one embodiment, an interpretation apparatus includes a translator, a calculator and a generator. The translator performs machine translation on a speech recognition result corresponding to an input speech audio from a first language into a second language to generate a machine translation result. The calculator calculates a word number based on a first time when the machine translation result is generated and a second time when output relating to a prior machine translation result generated prior to the machine translation result ends, the word number being 0 or larger. The generator omits at least the word number of words from the machine translation result to generate an abridged sentence output while being associated with the speech audio.

摘要： Disclosed herein are systems, computer-implemented methods, and tangible computer-readable storage media for captioning a media presentation. The method includes receiving automatic speech recognition (ASR) output from a media presentation and a transcription of the media presentation. The method includes selecting via a processor a pair of anchor words in the media presentation based on the ASR output and transcription and generating captions by aligning the transcription with the ASR output between the selected pair of anchor words. The transcription can be human-generated. Selecting pairs of anchor words can be based on a similarity threshold between the ASR output and the transcription. In one variation, commonly used words on a stop list are ineligible as anchor words. The method includes outputting the media presentation with the generated captions. The presentation can be a recording of a live event.

摘要： An audio processing system (100) accepts an audio bitstream having one of a plurality of predefined audio frame rates. The system comprises a front-end component (110), which receives a variable number of quantized spectral components, corresponding to one audio frame in any of the predefined audio frame rates, and performs an inverse quantization according to predetermined, frequency-dependent quantization levels. The front-end component may be agnostic of the audio frame rate. The audio processing system further comprises a frequency-domain processing stage (120) and a sample rate converter (130), which provide a reconstructed audio signal sampled at a target sampling frequency independent of the audio frame rate. By its frame-rate adaptability, the system can be configured to operate frame-synchronously in parallel with a video processing system that accepts plural video frame rates.

摘要： The specification and drawings present a new method, apparatus and software related product for handling interruptions, specifically passive interruption (or unintended interruption) for telephone communications (e.g., wireless) between users or user equipments (e.g., in LTE wireless systems). At least one monitoring electronic device can detect one or more unintended interruptions in an audio communication between at least two UEs in one or both communication directions before each of the one or more unintended interruptions occur. Upon this detection, at least one monitoring electronic device can provide an instruction to facilitate a shortened audio delay for audio data in at least one communication direction to offset the one or more unintended interruptions. The embodiments described herein may be applies to wireless/mobile communications and non-wireless/landline communications.
