A Theoretical Framework for Acoustic Neighbor Embeddings
Woojay Jeon
This paper provides a theoretical framework for interpreting acoustic neighbor embeddings, which are representations of the phonetic content of variable-width audio or text in a fi…
Timestamped Embedding-Matching Acoustic-to-Word CTC ASR
Woojay Jeon
In this work, we describe a novel method of training an embedding-matching word-level connectionist temporal classification (CTC) automatic speech recognizer (ASR) such that it dir…
Improvements to Embedding-Matching Acoustic-to-Word ASR Using Multiple-Hypothesis Pronunciation-Based Embeddings
Hao Yen, Woojay Jeon
In embedding-matching acoustic-to-word (A2W) ASR, every word in the vocabulary is represented by a fixed-dimension embedding vector that can be added or removed independently of th…
Acoustic Neighbor Embeddings
Woojay Jeon
This paper proposes a novel acoustic word embedding called Acoustic Neighbor Embeddings where speech or text of arbitrary length are mapped to a vector space of fixed, reduced dime…
Voice trigger detection from LVCSR hypothesis lattices using bidirectional lattice recurrent neural networks
Woojay Jeon, Leo Liu, Henry Mason
We propose a method to reduce false voice triggers of a speech-enabled personal assistant by post-processing the hypothesis lattice of a server-side large-vocabulary continuous spe…
On Modeling ASR Word Confidence
Woojay Jeon, Maxwell Jordan, Mahesh Krishnamoorthy
We present a new method for computing ASR word confidences that effectively mitigates the effect of ASR errors for diverse downstream applications, improves the word error rate of…
