Digital Einstein Experience: Fast Text-to-Speech for Conversational AI

no code implementations21 Jul 2021 Joanna Rownicka, Kilian Sprenkamp, Antonio Tripiana, Volodymyr Gromoglasov, Timo P Kunz

We describe our approach to create and deliver a custom voice for a conversational AI use-case.

Embeddings for DNN speaker adaptive training

no code implementations30 Sep 2019 Joanna Rownicka, Peter Bell, Steve Renals

In this work, we investigate the use of embeddings for speaker-adaptive training of DNNs (DNN-SAT) focusing on a small amount of adaptation data per speaker.

Speech Replay Detection with x-Vector Attack Embeddings and Spectral Features

no code implementations23 Sep 2019 Jennifer Williams, Joanna Rownicka

Our system used convolutional neural networks (CNNs) and a representation of the speech audio that combined x-vector attack embeddings with signal processing features.

Analyzing deep CNN-based utterance embeddings for acoustic model adaptation

no code implementations12 Nov 2018 Joanna Rownicka, Peter Bell, Steve Renals

We analyze the representations learned by deep CNNs and compare them with deep neural network (DNN) representations and i-vectors, in the context of acoustic model adaptation.
