Filed:

Aug 15, 2003

Appl. No.:

10/641658

Inventors:

David T. Kao - Sunnyvale CA, US
James J. Ashe - Saratoga CA, US

Assignee:

Analog Devices, Inc. - Norwood MA

International Classification:

H03M001/66

US Classification:

341144, 341154

Abstract:

A multiple-stage digitally-switched impedance has one “type B” stage and at least two “type A” stages. The type A stages are cascaded between high and low reference nodes and the type B stage. Each stage comprises a string of series-connected impedances and a switch network. A decoder responds to an digital input signal by controlling the switch networks to switch selectable portions of the strings in the type A stages into a series connection with the type B stage's string, and to control the type B stage's switch network to tap its string at a location to provide a impedance corresponding to the n-bit digital input signal between the final output node and at least one of the high and low reference nodes. Each stage provides a portion of the impedance's n-bit resolution, and the sum of the bits of resolution provided by each stage equals the total n-bit resolution.

International Classification:

G10L 13/10

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.

International Classification:

G10L 13/047
G10L 13/10

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.
