  • Publication number: 20210035551
    Abstract: A system for generating an output audio signal includes a context encoder, a text-prediction network, and a text-to-speech (TTS) model. The context encoder is configured to receive one or more context features associated with current input text and process the one or more context features to generate a context embedding associated with the current input text. The text-prediction network is configured to process the current input text and the context embedding to predict, as output, a style embedding for the current input text. The style embedding specifies a specific prosody and/or style for synthesizing the current input text into expressive speech The TTS model is configured to process the current input text and the style embedding to generate an output audio signal of expressive speech of the current input text. The output audio signal has the specific prosody and/or style specified by the style embedding.

  • Publication number: 20200372897
    Abstract: A method for estimating an embedding capacity includes receiving, at a deterministic reference encoder, a reference audio signal, and determining a reference embedding corresponding to the reference audio signal, the reference embedding having a corresponding embedding dimensionality. The method also includes measuring a first reconstruction loss as a function of the corresponding embedding dimensionality of the reference embedding and obtaining a variational embedding from a variational posterior. The variational embedding has a corresponding embedding dimensionality and a specified capacity. The method also includes measuring a second reconstruction loss as a function of the corresponding embedding dimensionality of the variational embedding and estimating a capacity of the reference embedding by comparing the first measured reconstruction loss for the reference embedding relative to the second measured reconstruction loss for the variational embedding having the specified capacity.

  • Publication number: 20080013724
    Abstract: A novel method and apparatus for protection of streamed media content is disclosed. In one aspect, the apparatus includes control means for governance of content streams or content objects, decryption means for decrypting content streams or content objects under control of the control means, and feedback means for tracking actual use of content streams or content objects. The control means may operate in accordance with rules received as part of the streamed content, or through a side-band channel. The rules may specify allowed uses of the content, including whether or not the content can be copied or transferred, and whether and under what circumstances received content may be “checked-out” of one device and used in a second device. The rules may also include or specify budgets, and a requirement that audit information be collected and/or transmitted to an external server. In a different aspect, the apparatus may include a media player designed to call plugins to assist in rendering content.

  • Patent number: 7172747
    Abstract: Spiral shaped fibers were utilized to prepare completely novel metal oxide nanotubes comprising solely metal oxides. The metal oxide nanotubes comprise solely a hollow cylinder shaped metal oxide which may contain hydroxyl groups constituting a double helix and having hole diameter distributions containing two peak hole diameters ranging from 1 to 2 nm and from 3 to 7 nm. The tubes may be obtained by forming spiral shaped fibers from a solution of compound 1 and compound 2 and using the fibers as a template for making the nanotubes. The hydrogen adsorption and storage capacity of the metal oxide nanotubes are extremely good.

  • Publication number: 20060159266
    Abstract: Protection of digital content using a specific application of block cipher cryptography is described. The digital content is encrypted using an encryption key and a calculated initialization vector. The digital content includes a plurality of strides of data and each stride includes a string of data to be encrypted and a block of data to be encrypted. The calculated initialization vector to be used to encrypt the block of data is derived from the string of data in the stride to be encrypted. Furthermore, the initialization vector is calculated by performing an exclusive disjunction function on a seed value and the string of data for each stride.
