Publication number: 20230104431Abstract: Described are techniques for noise-robust and speaker-independent keyword spotting (KWS) in an input audio signal that contains keywords used to activate voice-based human-computer interactions. A KWS system may combine the latent representation generated by a denoising autoencoder (DAE) with audio features extracted from the audio signal using a machine learning approach. The DAE may be a discriminative DAE trained with a quadruplet loss metric learning approach to create a highly-separable latent representation of the audio signal in the audio input feature space. In one aspect, spectral characteristics of the audio signal such as Log-Mel features are combined with the latent representation generated by a quadruplet loss variational DAE (QVDQE) as input to a DNN KWS classifier.Type: ApplicationFiled: February 22, 2022Publication date: April 6, 2023Applicant: Cypress Semiconductor CorporationInventors: Aidan Smyth, Ashutosh Pandey, Avik Santra

Publication number: 20230051344Abstract: Implementations disclosed describe methods and systems to perform the methods of optimizing a size of memory used for accumulation of neural node outputs and for supporting multiple computational paths in neural networks. In one example, a size of memory used to perform neural layer computations is reduced by performing nodal computations in multiple batches, followed by rescaling and accumulation of nodal outputs. In another example, execution of parallel branches of neural node computations include evaluating, prior to the actual execution, the amount of memory resources needed to execute a particular order of branches sequentially and select the order that minimizes this amount or keeps this amount below a target threshold.Type: ApplicationFiled: March 25, 2022Publication date: February 16, 2023Applicant: Cypress Semiconductor CorporationInventors: Kaiping LI, Aidan SMYTH, Ashutosh PANDEY
