Appl. No.:

11/492210

Inventors:

Vivek Kumar - San Jose CA, US
Joakim Linde - Palo Alto CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04L 7/00
H04L 25/00
H04L 25/40

US Classification:

375372, 375371, 375373, 375376, 375355, 713503, 370505, 370229

Abstract:

Methods and apparatuses for compensating for differences in communication system transmit and receive clock signal frequencies include buffer timing modification and sample addition. In buffer timing modification, a buffer clock signal is interrupted as needed to slow the rate of data through the buffer. In sample addition, pseudo samples are inserted into a data stream to compensate for timing differences.

International Classification:

H03M 13/00

US Classification:

714774, 714 3, 714747

Abstract:

Systems and methods are described for managing bit errors present in an encoded bit stream representative of a portion of an audio signal, wherein the encoded bit stream is received via a channel in a wireless communications system. The channel may comprise, for example, a Synchronous Connection-Oriented (SCO) channel or an Extended SCO (eSCO) channel in a Bluetooth wireless communications system.

International Classification:

G10L 13/033
G10L 13/047

Abstract:

Novel methods and systems for adapting a voice cloning synthesizer for a new speaker using real speech data are disclosed. Utterances from one or more target speakers are parameterized and are used to initialize an embedding vector for use with a voice synthesizer, by means of clustering the utterance data and determining the centroid of the data, using a speaker identification neural network, and/or by finding the closest stored embedded vector to the utterance data.

International Classification:

G06N 20/00
G06F 16/903

Abstract:

Systems and methods for selecting items from a pool of items based on comparisons of composite embeddings are disclosed. A first initial embedding is obtained from a first database for each item in a pool of items and a second initial embedding is obtained from a second database for each item in the pool of items. The first initial embedding is generated using a first embedding model and the second initial embedding is generated using a second embedding model. A first composite embedding is generated for each item in the pool of items comprising the first initial embedding and the second initial embedding; and compare the first composite embedding for each item in the pool of items to a first anchor embedding, wherein the first anchor embedding comprises a first initial anchor embedding generated using the first embedding model and a second initial anchor embedding generated using the second embedding model.

International Classification:

G10L 19/022
G06F 3/16
G06N 3/08
G06N 3/04

Abstract:

Computer-implemented methods for training a neural network, as well as for implementing audio encoders and decoders via trained neural networks, are provided. The neural network may receive an input audio signal, generate an encoded audio signal and decode the encoded audio signal. A loss function generating module may receive the decoded audio signal and a ground truth audio signal, and may generate a loss function value corresponding to the decoded audio signal. Generating the loss function value may involve applying a psychoacoustic model. The neural network may be trained based on the loss function value. The training may involve updating at least one weight of the neural network.
