📄 Our paper on synthetic speech augmentation for Estonian and Slovenian ASR is officially out in Machine Learning with Applications. The Estonian and Slovenian Parakeet and Whisper models have been on the Hub since March. This is the peer-reviewed paper behind them, with the full adaptation ladder, ablations, and a large-scale error analysis. Quick recap: we fine-tuned Parakeet-TDT-0.6B-v3 and Whisper-large-v3 on identical data, CommonVoice 17 alone and with ~10 hours per language of synthetic speech (LLM-generated text, LLM-as-judge filtering, TTS). Synthetic speech improves in-domain recognition for every model-language pair, cutting CV17 test WER by 1.3 to 3.7 points over real-data-only fine-tuning. Parakeet, at less than half Whisper's size, reaches the lower WER in every fine-tuned condition. Across 95,070 re-aligned sentence pairs, the architecture largely decides which error types persist, while the adaptation regime mainly changes how many. 📦 Resources - Paper: https://www.sciencedirect.com/science/article/pii/S2666827026002082 - Parakeet ET: https://huggingface.co/yuriyvnv/parakeet-tdt-0.6b-estonian - Parakeet SL: https://huggingface.co/yuriyvnv/parakeet-tdt-0.6b-slovenian - Whisper ET: https://huggingface.co/yuriyvnv/whisper-large-v3-estonian - Whisper SL: https://huggingface.co/yuriyvnv/whisper-large-v3-slovenian - Dataset: https://huggingface.co/datasets/yuriyvnv/synthetic_asr_et_sl - Code: https://github.com/yuriyvnv/TTS-Augmented-ASR If you train ASR for other morphologically rich, low-resource languages, I'd like to hear whether the same error patterns show up. @reach-vb @ylacombe @hf-audio #speech #asr #syntheticdata #lowresource #estonian #slovenian

🏥 Two medical English ASR models are up
Hey, back from a long holiday. While I was out the team kept working on this one and the results are pretty interesting. Medical English ASR, evaluated against the published MultiMed paper.

🩺 yuriyvnv/parakeet-tdt-0.6b-EN-Medical
🩺 yuriyvnv/Qwen3-ASR-1.7B-EN-Medical

Both trained on MultiMed (leduckhai/MultiMed) mixed with Common Voice 17 English train and validation. Mixing CV in prevents catastrophic forgetting of general English. Medical-only training without CV cost us 5 absolute WER points on general English.

📊 Normalized WER on MultiMed-en test, same protocol as the paper:

Parakeet 0.6B zero-shot: 19.22
Parakeet 0.6B fine-tuned: 14.31 (25% relative reduction)

Qwen3-ASR 1.7B zero-shot: 16.41 (although here we had catastrophic forgetting on CV test set)
Qwen3-ASR 1.7B fine-tuned: 16.50

@hf-audio @QwenLM thanks for the toolkits. Big thanks to @leduckhai and the MultiMed authors for the dataset.

📄 The WAVe paper is officially out in the Information Sciences Journal.

You saw the PT and NL model releases earlier this year. This is the peer-reviewed paper behind them, with the full method, ablations, and downstream ASR evaluation.

Quick recap: WAVe is a 1B multimodal embedding model that filters synthetic speech at the word level, not the sentence level. On Portuguese ASR it cuts training steps by 34%, improves cross-domain generalization by 50%, and matches WER with 30% less synthetic data.

📦 Resources
- Paper: https://www.sciencedirect.com/science/article/pii/S0020025526005220

- Collection: https://huggingface.co/collections/yuriyvnv/multi-modal-embeddings-for-synthetic-transcript-filtering
- Code: https://github.com/yuriyvnv/WAVe

If you train ASR on synthetic or back-translated data, would like to see WAVe benchmarked on other languages.

🔊 Four Qwen3-ASR (0.6B and 1.7B) Fine-Tunes for Portuguese and Dutch.

Both the 1.7B and 0.6B variants of Alibaba's Qwen3-ASR, fine-tuned for European Portuguese and Dutch and bundled in a single collection.

🔗 Collection: https://huggingface.co/collections/yuriyvnv/qwen-asr-for-portuguese-and-dutch-17b-and-06b

Headline numbers — Common Voice 22 test, with the zero-shot baseline.
🇵🇹 Qwen3-ASR-1.7B-PT — 12.91% → 8.50% WER (-34%)
🇵🇹 Qwen3-ASR-0.6B-PT — 18.26% → 11.85% WER (-35%)
🇳🇱 Qwen3-ASR-1.7B-NL — 6.68% → 5.28% WER (-21%)
🇳🇱 Qwen3-ASR-0.6B-NL — 12.46% → 8.31% WER (-33%)

The 0.6B variants are the more interesting half of the release. They give up only a few WER points compared to the 1.7B at a third of the parameters — relevant for edge hardware, CPU inference, or anywhere keeping inference cost down. The Dutch 0.6B in particular lands at 8.3% WER on CV22, competitive with much larger systems.

The Dutch 1.7B started from a strong 6.7% zero-shot, so the absolute gain is smaller — Qwen already handles Dutch well, and the fine-tune mostly sharpens it on Common Voice's casing and punctuation conventions.

Training stuck close to Qwen's official SFT recipe (lr 2e-5, linear schedule, 2% warmup, bf16, gradient checkpointing on a single H100). The data is the differentiator: Common Voice 22 train + validation augmented with synthetic OpenAI-TTS speech, filtered by the WAVe multimodal embedding model that scores clips at the word level and drops the ones that don't align well with their transcripts.

Thanks! Just pushed the repo public: github.com/yuriyvnv/TTS-Augmented-ASR

This is the codebase behind a paper I wrote on Estonian and Slovenian, so you'll find the full pipeline there: not just the Parakeet fine-tuning scripts, but also the synthetic data generation (LLM text diversification + OpenAI TTS synthesis) that powers the augmentation. Everything was trained on a single NVIDIA H100.

One thing worth knowing for African languages:

Parakeet v3 is only pretrained on 25 languages, so you'd be doing cross-lingual transfer from scratch. The base won't recognize the language zero-shot, but fine-tuning still works — just expect a much rougher starting point than what you saw in my models.
Always evaluate zero-shot first. I had one language (Polish) where fine-tuning actually made things worse due to domain mismatch, or the learning rate was too low (still analyzing why this happened).
Standard recipe worked across everything I tried: AdamW, lr=5e-5, cosine annealing, 10% warmup, bf16, batch 32-64, early stopping on val_wer. The larger the batch size, especially for parakeet models, the better the gradient flow during training, since the model is compact.
Happy to help if you hit anything weird.

🎯 WAVe-1B-Multimodal-NL: Word-Level Speech Quality Assessment for Dutch

Following the release of the Portuguese model, we're releasing the Dutch variant of WAVe — a 1B multimodal embedding model that assesses synthetic speech quality at the word level, thereby improving the quality of synthetically augmented datasets for training ASR models.

Trained on CommonVoice 16.1 Dutch with 5 corruption strategies, this model catches mispronunciations, timing errors, and prosody issues in synthetic data that sentence-level embeddings miss entirely.
Resources

- Dutch model: yuriyvnv/WAVe-1B-Multimodal-NL
- Portuguese model: yuriyvnv/WAVe-1B-Multimodal-PT
- Code: https://github.com/yuriyvnv/WAVe

This model builds on CommonVoice Dutch data — thanks to @mozilla and the CommonVoice community for making multilingual speech data accessible.

Would be great to hear from the Dutch NLP community — @BramVanroy @GroNLP — especially if you're working on Dutch ASR or TTS pipelines where quality filtering could help. Also tagging @hf-audio as this sits at the intersection of speech processing and data curation.

🔥 Hello Everyone, given the community's increased interest in the WAVe for the Portuguese Language, the team has retrained the model for over 100 epochs to further extend learning. The results are much better than those from the previous version with 30 epochs.
Key improvements:

Metric	30 ep	100 ep	Change
Loss	0.49	0.22	-56%
Alignment Gap	0.079	0.118	+49%
Corrupt Similarity	0.31	0.23	-25%

The biggest win is the alignment gap nearly doubling -- the model is now much better at catching word-level errors like mispronunciations and timing artifacts. Corrupt pairs get
penalized harder (0.23 vs 0.31), so the filtering threshold becomes more reliable.

Same repo, same API, drop-in replacement:

model = AutoModel.from_pretrained("yuriyvnv/WAVe-1B-Multimodal-PT", trust_remote_code=True)

Updated README of the model card includes side-by-side training curves for both versions, check it out.

Hello everyone, yesterday there were minor problems that prevented the usage of the Embedding model. Mainly because of the Processor Class.
Posting here that the team has already solved the bugs.
If there is any problem with your usage, first delete the cached model (.cache folder in Hugging Face), redownload it, and if the issue persists, post a thread on the model page.

🎯 WAVe: 1B Multimodal Embedding Model for Word-Level Speech Quality

Multimodal embeddings for speech + transcript that verify quality at the word level, not just sentence level. Catches mispronunciations, timing errors, and prosody issues that sentence-level filters miss.

📊 Impact on Portuguese ASR:
• 34% reduction in training steps
• 50% better cross-domain generalization
• 30% less synthetic data needed
• Word-aligned attention finds errors other methods miss

🏗️ Architecture:
• Text: XLM-RoBERTa (278M params)
• Audio: Wav2Vec2-BERT 2.0 (581M params)
• Word Alignment: Multi-head attention + GLU (14M params)
• Total: 1B parameters

from transformers import AutoModel, AutoProcessor

  processor = AutoProcessor.from_pretrained(
      "yuriyvnv/WAVe-1B-Multimodal-PT",
      trust_remote_code=True
  )
  model = AutoModel.from_pretrained(
      "yuriyvnv/WAVe-1B-Multimodal-PT",
      trust_remote_code=True
  )

# Assess speech-transcript alignment

inputs = processor(text="Olá, como está?", audio=audio_array, sampling_rate=16000, return_tensors="pt")
  quality = model(**inputs).quality_score.item()

Perfect for filtering synthetic speech datasets before ASR training.
