Hierarchical Generative Modeling for Controllable Speech Synthesis

ICLR 2019poster

This paper proposes a neural end-to-end text-to-speech (TTS) model which can control latent attributes in the generated speech that are rarely annotated in the training data, such as speaking style, accent, background noise, and recording conditions. The model is formulated as a conditional generati…

An Analysis of Incorporating an External Language Model into a Sequence-to-Sequence Model

ICASSP 2018accepted

Attention-based sequence-to-sequence models for automatic speech recognition jointly train an acoustic model, language model, and alignment mechanism. Thus, the language model component is only trained on transcribed audio-text pairs. This leads to the use of shallow fusion with an external language…

Improving the Performance of Online Neural Transducer Models

ICASSP 2018accepted

Having a sequence-to-sequence model which can operate in an online fashion is important for streaming applications such as Voice Search. Neural transducer is a streaming sequence-to-sequence model, but has shown a significant degradation in performance compared to non-streaming models such as Listen…

Minimum Word Error Rate Training for Attention-Based Sequence-to-Sequence Models

ICASSP 2018accepted

Sequence-to-sequence models, such as attention-based models in automatic speech recognition (ASR), are typically trained to optimize the cross-entropy criterion which corresponds to improving the log-likelihood of the data. However, system performance is usually measured in terms of word error rate…

Multi-Dialect Speech Recognition with a Single Sequence-to-Sequence Model

ICASSP 2018accepted

Sequence-to-sequence models provide a simple and elegant solution for building speech recognition systems by folding separate components of a typical system, namely acoustic (AM), pronunciation (PM) and language (LM) models into a single neural network. In this work, we look at one such sequence-to-…

No Need for a Lexicon? Evaluating the Value of the Pronunciation Lexica in End-to-End Models

ICASSP 2018accepted

For decades, context-dependent phonemes have been the dominant sub-word unit for conventional acoustic modeling systems. This status quo has begun to be challenged recently by end-to-end models which seek to combine acoustic, pronunciation, and language model components into a single neural network.…

State-of-the-Art Speech Recognition with Sequence-to-Sequence Models

ICASSP 2018accepted

Attention-based encoder-decoder architectures such as Listen, Attend, and Spell (LAS), subsume the acoustic, pronunciation and language model components of a traditional automatic speech recognition (ASR) system into a single neural network. In previous work, we have shown that such architectures ar…

Transfer Learning from Speaker Verification to Multispeaker Text-To-Speech Synthesis

NeurIPS 2018poster

We describe a neural network-based system for text-to-speech (TTS) synthesis that is able to generate speech audio in the voice of many different speakers, including those unseen during training. Our system consists of three independently trained components: (1) a speaker encoder network, trained on…
