Bi-APC: Bidirectional Autoregressive Predictive Coding for Unsupervised Pre-training and Its Application to Children's ASR

Ruchao Fan, Amber Afshan, Abeer Alwan

We present a bidirectional unsupervised model pre-training (UPT) method and apply it to children's automatic speech recognition (ASR). An obstacle to improving child ASR is the sca…

Analysis of Disfluency in Children's Speech

Trang Tran, Morgan Tinkler, Gary Yeung +2

Disfluencies are prevalent in spontaneous speech, as shown in many studies of adult speech. Less is understood about children's speech, especially in pre-school children who are st…

Speaker discrimination in humans and machines: Effects of speaking style variability

Amber Afshan, Jody Kreiman, Abeer Alwan

Does speaking style variation affect humans' ability to distinguish individuals from their voices? How do humans compare with automatic systems designed to discriminate between voi…

Exploring the Use of an Unsupervised Autoregressive Model as a Shared Encoder for Text-Dependent Speaker Verification

Vijay Ravi, Ruchao Fan, Amber Afshan +2

In this paper, we propose a novel way of addressing text-dependent automatic speaker verification (TD-ASV) by using a shared-encoder with task-specific decoders. An autoregressive…
