Nemotron 3.5 ASR overview: multilingual audio across 40 language-locales is transcribed by a cache-aware FastConformer-RNNT model with language-ID prompting into punctuated text with an automatic language tag

Concurrent streams supported on a single H100: Nemotron ASR streaming vs Parakeet RNNT, across chunk sizes

[!Note] This model is the multilingual extension of nvidia/nemotron-speech-streaming-en-0.6b, adding language-ID prompt conditioning to support transcription across 40 language-locales from a single model.

Nemotron 3.5 ASR is a multilingual, streaming Automatic Speech Recognition (ASR) model engineered to deliver high-quality multilingual transcription across both low-latency streaming and high-throughput batch workloads. Developed by NVIDIA, this 600M parameter model transcribes speech into text with native support for punctuation and capitalization, and offers runtime flexibility with configurable chunk sizes, including 80ms, 160ms, 320ms, 560ms, and 1120ms.

By leveraging a state-of-the-art Cache-Aware FastConformer-RNNT architecture, the model eliminates redundant overlapping computations common in traditional "buffered" streaming. This allows it to process only new audio chunks while reusing cached encoder context, significantly improving computational efficiency and minimizing end-to-end delay without sacrificing accuracy.

It was trained on a massive ASR dataset and is engineered to perform across diverse and challenging acoustic conditions.

This model is ready for commercial use.

Why Choose Nemotron 3.5 ASR?

🌍 Single Multilingual Model: Transcribes 40 language-locales from one model through language-ID prompt conditioning, with optional automatic language detection.
⚡ Native Streaming Architecture: Cache-aware design enables efficient processing of continuous audio streams, designed and optimized for low-latency voice agent applications.
💰 Improved Operational Efficiency: Delivers superior throughput compared to traditional buffered streaming approaches. This allows for a higher number of parallel streams within the same GPU memory constraints, directly reducing operational costs for production environments.
🎛️ Dynamic Runtime Flexibility: Choose the optimal operating point on the latency-accuracy Pareto curve at inference time. No re-training is required to adjust for different use-case requirements.
📝 Punctuation & Capitalization: Built-in support for punctuation and capitalization in output text.
🔧 Fine-tuning: Check our blog post of how to fine-tune Nemotron 3.5 ASR to improve these languages, including before/after results.

Supported Languages

The model supports 40 language-locales in total, across three tiers:

Transcription-ready (19 locales): highest-accuracy ASR, ready out of the box.
Broad-coverage (13 locales): production ASR across an additional 13 locales.
Adaptation-ready (8 locales): recognized by the tokenizer; fine-tune on in-domain data to unlock full transcription.

Tier	Languages (locales)
Transcription-ready (19 locales)	English (en-US, en-GB), Spanish (es-US, es-ES), French (fr-FR, fr-CA), Italian (it-IT), Portuguese (pt-BR, pt-PT), Dutch (nl-NL), German (de-DE), Turkish (tr-TR), Russian (ru-RU), Arabic (ar-AR), Hindi (hi-IN), Japanese (ja-JP), Korean (ko-KR), Vietnamese (vi-VN), Ukrainian (uk-UA)
Broad-coverage (13 locales)	Polish (pl-PL), Swedish (sv-SE), Czech (cs-CZ), Norwegian Bokmål (nb-NO), Danish (da-DK), Bulgarian (bg-BG), Finnish (fi-FI), Croatian (hr-HR), Slovak (sk-SK), Mandarin (zh-CN), Hungarian (hu-HU), Romanian (ro-RO), Estonian (et-EE)
Adaptation-ready (8 locales)	Greek (el-GR), Lithuanian (lt-LT), Latvian (lv-LV), Maltese (mt-MT), Slovenian (sl-SI), Hebrew (he-IL), Thai (th-TH), Norwegian Nynorsk (nn-NO)

Note: Transcription-ready and broad-coverage locales (32 total) produce ASR transcription out of the box; adaptation-ready locales require fine-tuning on in-domain data to enable full transcription. The model supports uppercase and lowercase letters, punctuation, spaces, and apostrophes.

Note: We would recommend Nemotron ASR Streaming (English) model for English-only transcription use cases. For all other transcription ready locales, we recommend Nemotron 3.5 ASR to leverage its expanded multilingual capabilities.

[!Tip] Automatic language detection / language tagging: When run with target_lang=auto, the model detects the spoken language and emits the corresponding language code/tag in the output following the terminal punctuation. This lets a single deployment transcribe mixed-language traffic and automatically label each utterance with its detected language — no separate language-ID component required.

Model Architecture

Architecture Type: FastConformer-CacheAware-RNNT with Prompt

This model consists of a cache-aware streaming Parakeet (FastConformer) encoder with an RNN-T decoder and language-ID prompt conditioning. It is based on the Cache-Aware [1] FastConformer [2] architecture with 24 encoder layers and an RNNT (Recurrent Neural Network Transducer) decoder. The cache-aware streaming design enables efficient processing of audio in chunks while maintaining context from previous frames. Unlike buffered inference, this model maintains caches for all encoder self-attention and convolution layers. This enables reuse of hidden states at every streaming step, where cached activations eliminate redundant computations. As a result, there are no overlapping computations; each processed frame is strictly non-overlapping. This model leverages prompts to guide the transcription process, enabling language-specific transcription from a single ASR model through language ID conditioning.

Nemotron 3.5 ASR architecture: FastConformer encoder and language-ID encoding are concatenated, projected, and fed to the RNNT decoder

The language-ID prompt is fused with the acoustic representation as follows:

FastConformer encoder processes audio into an acoustic embedding of shape (D=1024, T).
Language Encoding expands a 128-dim one-hot language vector across the time axis → (K=128, T), broadcasting the language identity to every frame.
Concatenation along the feature axis → fused tensor (D + K, T).
Projection layer maps the fused features to the RNNT decoder.

Network Architecture:

Encoder: Cache-Aware FastConformer with 24 layers
Decoder: RNNT (Recurrent Neural Network Transducer)
Parameters: 600M

This model was developed based on nvidia/nemotron-speech-streaming-en-0.6b.

Results at a Glance

ASR performance is measured using Word Error Rate (WER) on the FLEURS test sets. Accuracy stays strong across both modes and improves as the chunk size grows, while remaining competitive even at the lowest-latency 80ms setting. Full tables are in Performance.

FLEURS average WER vs streaming chunk size (LangID vs Auto-detect)

FLEURS WER by language: LangID vs Auto-detect at 320ms chunk

Note: Japanese and Korean are measured using Character Error Rate (CER) rather than WER, as is standard for these languages.

Throughput & Efficiency

Despite being roughly half the size (0.6B vs. 1.1B), Nemotron 3.5 ASR serves far more concurrent streams at far lower latency than the Parakeet RNNT 1.1B multilingual model, which runs on buffered streaming. The cache-aware streaming design avoids the redundant recomputation of buffered inference, so a single H100 can sustain dramatically higher concurrency at every chunk size — directly lowering the cost per stream in production. At the lowest-latency 80ms setting, Nemotron sustains ~17× more concurrent streams (240 vs. 14); at the 1120ms setting it sustains 6× more (2,400 vs. 400). The latency-vs-concurrency curves tell the same story: Nemotron (solid green) holds low final-token latency well past 1,000 parallel requests, while Parakeet RNNT 1.1B (dashed blue) saturates after only a few hundred.

Median final-token latency vs number of parallel requests on a single H100, Nemotron vs Parakeet RNNT across chunk sizes

Measured on a single NVIDIA H100. Throughput is the number of real-time streams sustainable in parallel; latency is the median final-token latency at a given level of concurrency.

NVIDIA NeMo

To train, fine-tune or perform inference with this model, you will need to install NVIDIA NeMo [4]. We recommend you install it after you've installed python >= 3.11, Cython and latest PyTorch version.

bash

apt-get update && apt-get install -y libsndfile1 ffmpeg
pip install Cython packaging
pip install git+https://github.com/NVIDIA/NeMo.git@main#egg=nemo_toolkit[asr]

How to Use this Model

The model is available for use in the NeMo Framework, and can be used as a pre-trained checkpoint for inference or for fine-tuning on another dataset.

You can also run it with 🤗 Transformers (more below).

Loading the Model

python

import nemo.collections.asr as nemo_asr
asr_model = nemo_asr.models.ASRModel.from_pretrained(model_name="nvidia/nemotron-3.5-asr-streaming-0.6b")

Streaming Inference

You can use the cache-aware streaming inference script from NeMo - NeMo/examples/asr/asr_cache_aware_streaming/speech_to_text_cache_aware_streaming_infer.py

This is a prompt-conditioned multilingual model: pass the target language with target_lang (e.g. en-US, es-ES, de-DE), or use target_lang=auto for automatic language detection.

bash

cd NeMo
python examples/asr/asr_cache_aware_streaming/speech_to_text_cache_aware_streaming_infer.py \
    model_path=<model_path> \
    dataset_manifest=<dataset_manifest> \
    batch_size=<batch_size> \
    target_lang=<lang_id> \ #language key (e.g. en-US) or "auto" for automatic language detection
    att_context_size="[56,13]" \ #set the second value to the desired right context from {0,1,3,6,13}
    strip_lang_tags=true \ #true: remove the detected language tag from the text; false: keep it in the output
    output_path=<output_folder>

strip_lang_tags controls how the detected language tag is handled in the output. The model appends a language tag (e.g. <en-US>) after the transcript's terminal punctuation:

strip_lang_tags=false (keep): the tag is left in the output, so you can read the detected language directly from each utterance — useful for mixed-language traffic and language labeling.
strip_lang_tags=true (remove): the tag is stripped, leaving only the clean transcript text — useful when you only need the spoken words.

Setting up Streaming Configuration

Latency is defined by the att_context_size param, where att_context_size = {num_frames_left_context, num_frame_right_context}, all measured in 80ms frames:

[56, 0]: Chunk size = 1 (1 × 80ms = 0.08s)
[56, 1]: Chunk size = 2 (2 × 80ms = 0.16s)
[56, 3]: Chunk size = 4 (4 × 80ms = 0.32s)
[56, 6]: Chunk size = 7 (7 × 80ms = 0.56s)
[56, 13]: Chunk size = 14 (14 × 80ms = 1.12s)

Here, chunk size = current frame + right context; each chunk is processed in non-overlapping fashion.

🤗 Transformers usage

This checkpoint also runs with 🤗 Transformers. The target language is passed through the processor's language argument: a locale such as en-US/de-DE, a bare code such as de, or auto for automatic language detection. In auto mode the model appends an <xx-XX> language tag after the transcript's terminal punctuation; it is a special token, so decoding with skip_special_tokens=True strips it (clean transcript) and skip_special_tokens=False keeps it for language labeling.

Nemotron3_5Asr is available in 🤗 Transformers starting from v5.13.0.

pip install "transformers>=5.13.0"

Performance

ASR performance is measured using the Word Error Rate (WER). The tables below report WER (%) on the FLEURS test sets across configurable streaming chunk sizes, in two modes:

Language Input (LangID): the target language is provided to the model.
Auto-detect: the model automatically detects the spoken language.

Note: Japanese, Korean, and Mandarin are evaluated using Character Error Rate (CER) rather than WER, as is standard for these languages. Note on text normalization: WER/CER are computed after text normalization that aligns the reference and hypothesis (e.g., casing, punctuation, numerals, and formatting conventions). Normalization is not perfect across all 40 language-locales, and residual mismatches between normalized text can inflate the reported error rates — actual transcription quality may be somewhat better than the numbers suggest.
