One TTS Alignment To Rule Them All [article]

Rohan Badlani, Adrian Łancucki, Kevin J. Shih, Rafael Valle, Wei Ping, Bryan Catanzaro
2021 arXiv   pre-print
Speech-to-text alignment is a critical component of neural textto-speech (TTS) models. Autoregressive TTS models typically use an attention mechanism to learn these alignments on-line.  ...  In our experiments, the alignment learning framework improves all tested TTS architectures, both autoregressive (Flowtron, Tacotron 2) and non-autoregressive (FastPitch, FastSpeech 2, RAD-TTS).  ...  Similar to GlowTTS [6] and RAD-TTS [12] , we compute the soft alignment distribution based on the learned pairwise affinity between all text tokens and mel frames, which is normalized with softmax across  ...

Tree-Based Statistical Machine Translation: Experiments with the English and Brazilian Portuguese Pair

Daniel Beck, Helena Caseli
2013 Learning and Nonlinear Models  
However, this lack on explicit linguistic knowledge makes them unable to model some linguistic phenomena.  ...  Current state-of-the-art approaches rely only on statistical methods that gather all necessary knowledge from parallel corpora.  ...  This is due to the fact that extracts only the minimal rules from the alignment graphs and therefore only one derivation is considered for all alignment graphs.  ...

Transforming non textually aligned SPMD programs into textually aligned SPMD programs by using rewriting rules

Wadoud Bousdira
2019 2019 International Conference on High Performance Computing & Simulation (HPCS)  
We propose a set of transformation rules using rewriting techniques which allows to turn a non-textually aligned program to be textually aligned.  ...  Then, the textual alignement of the synchronization barriers that is defined prevents deadlocks. However, the textual alignement property is not verified by all SPMD programs.  ...  Of course, the transformation that we propose does not guarantee to turn all non-textually aligned SPMD programs to textually aligned ones.  ...

Probing the phonetic and phonological knowledge of tones in Mandarin TTS models [article]

Jian Zhu
2019 arXiv   pre-print
On the other hand, it is also suggested that linguistically informed stimuli should be included in the training and the evaluation of TTS models.  ...  Results show that both baseline Tacotron 2 and Tacotron 2 with BERT embeddings capture the surface tonal coarticulation patterns well but fail to consistently apply the Tone-3 sandhi rule to novel sentences  ...  Error analysis shows that the TTS models are not simply applying a fixed Tone-3 sandhi pattern to all trisyllabic words.  ...

VRAIN-UPV MLLP's system for the Blizzard Challenge 2021 [article]

Alejandro Pérez-González-de-Martos, Albert Sanchis, Alfons Juan
2021 arXiv   pre-print
The SH1 task consisted in building a Spanish text-to-speech system trained on (but not limited to) the corpus released by the Blizzard Challenge 2021 organization.  ...  Only one system among other 11 participants achieved better naturalness than ours. Concretely, it achieved a naturalness MOS of 3.61 compared to 4.21 for real samples.  ...  Acknowledgements The research leading to these results has received funding from the Government of Spain's research project Multisub (ref. RTI2018-094879-B-I00, MCIU/AEI/FEDER,EU). References  ...

Testing the consistency assumption: Pronunciation variant forced alignment in read and spontaneous speech synthesis

Rasmus Dall, Sandrine Brognaux, Korin Richmond, Cassia Valentini-Botinhao, Gustav Eje Henter, Julia Hirschberg, Junichi Yamagishi, Simon King
2016 2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
We present evidence that in the alignment of both standard read prompts and spontaneous speech this phoneme sequence is often wrong, and that this is likely to have a negative impact on acoustic models  ...  A perceptual evaluation of HMM-based voices showed that spontaneous models trained on this improved alignment also improved standard synthesis, despite breaking the consistency assumption.  ...  Earlier work on spontaneous TTS admitted problems with speech alignment [11, Ch. 3] .  ...

Acoustic-dependent Phonemic Transcription for Text-to-speech Synthesis

Kévin Vythelingum, Yannick Estève, Olivier Rosec
2018 Interspeech 2018  
The overall quality of TTS highly depends on the accuracy of phonemic transcriptions.  ...  On a French TTS dataset, we show that we can detect up to 90.5% of errors of a state-of-the-art graphemeto-phoneme conversion system by annotating less than 15.8% of phonemes as erroneous.  ...  conversion model and use them during phoneme recognition.  ...

2012 2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
TTS systems typically rely on a lexicon to look up pronunciations for each word in the input text.  ...  Text-to-speech synthesis (TTS) is the final stage in the speech-tospeech (S2S) translation pipeline, producing an audible rendition of translated text in the target language.  ...  [7] , and combined them to generate a many-to-many (bidirectional) word alignment for phrase translation rule extraction.  ...

Information fusion approaches to the automatic pronunciation of print by analogy

POS-tagging a bilingual parallel corpus: methods and challenges

Irene Doval
2017 Research in Corpus Linguistics  
On the one hand, tagging performance degrades significantly when applied to fictional data and, on the other, pre-existing annotation schemes are all language specific.  ...  To further improve accuracy during post-editing, the author has developed a common tagset and identified major error patterns.  ...  The tagger POS taggers can be grouped into two main types: rule-based and stochastic. Rule-based taggers start by assigning all possible tags to words using a dictionary.  ...
