Interspeech 20222022In this work we improve the style representation for cross-lingual style transfer. Specifically, we improve the Spanish representation across four styles, Newscaster, DJ, Excited, and Disappointed, whilst maintaining a single speaker identity for which we only have English samples. This is achieved using Learned Conditional Prior VAE (LCPVAE), a hierarchical Variational Auto Encoder (VAE) approach. A secondary

KDD 20222022Multi-Task Learning (MTL) is widely-accepted in Natural Language Processing as a standard technique for learning multiple related tasks in one model. Training an MTL model requires having the training data for all tasks available at the same time. As systems usually evolve over time, (e.g., to support new functionalities), adding a new task to an existing MTL model usually requires retraining the model

Interspeech 20222022Speaker identification (SID) in the household scenario (e.g., for smart speakers) is an important but challenging problem due to limited number of labeled (enrollment) utterances, confusable voices, and demographic imbalances. Conventional speaker recognition systems generalize from a large random sample of speakers, causing the recognition to underperform for households drawn from specific cohorts or otherwise

Interspeech 20222022An essential design decision for multilingual Neural Text-ToSpeech (NTTS) systems is how to represent input linguistic features within the model. Looking at the wide variety of approaches in the literature, two main paradigms emerge, unified and separate representations. The former uses a shared set of phonetic tokens across languages, whereas the latter uses unique phonetic tokens for each language. In

Interspeech 20222022Generating expressive and contextually appropriate prosody remains a challenge for modern text-to-speech (TTS) systems. This is particularly evident for long, multi-sentence inputs. In this paper, we examine simple extensions to a Transformer-based FastSpeech-like system, with the goal of improving prosody for multi-sentence TTS. We find that long context, powerful text features, and training on multi-speaker
