+
+## Model Architecture
+
+Canary is an encoder-decoder model with FastConformer [1] encoder and Transformer Decoder [2]. 
+With audio features extracted from the encoder, task tokens such as `<source language>`, `<target language>`, `<task>` and `<toggle PnC>` 
+are fed into the Transformer Decoder to trigger the text generation process. Canary uses a concatenated tokenizer [5] from individual 
+SentencePiece [3] tokenizers of each language, which makes it easy to scale up to more languages. 
+The Canay-1B model has 24 encoder layers and 24 layers of decoder layers in total.
+
+
+## NVIDIA NeMo
+
+To train, fine-tune or Transcribe with Canary, you will need to install [NVIDIA NeMo](https://github.com/NVIDIA/NeMo). We recommend you install it after you've installed Cython and latest PyTorch version.
+```
+pip install git+https://github.com/NVIDIA/NeMo.git@r1.23.0#egg=nemo_toolkit[asr]
+```
+
+
+## How to Use this Model
+
+The model is available for use in the NeMo toolkit [4], and can be used as a pre-trained checkpoint for inference or for fine-tuning on another dataset.
+
+### Loading the Model
+
+```python
+from nemo.collections.asr.models import EncDecMultiTaskModel
+
+# load model
+canary_model = EncDecMultiTaskModel.from_pretrained('nvidia/canary-1b')
+
+# update dcode params
+decode_cfg = canary_model.cfg.decoding
+decode_cfg.beam.beam_size = 1
+canary_model.change_decoding_strategy(decode_cfg)
+```
+
+### Input Format
+Input to Canary can be either a list of paths to audio files or a jsonl manifest file.
+
+If the input is a list of paths, Canary assumes that the audio is English and Transcribes it. I.e., Canary default behaviour is English ASR. 
+```python
+predicted_text = canary_model.transcribe(
+    paths2audio_files=['path1.wav', 'path2.wav'],
+    batch_size=16,  # batch size to run the inference with
+)[0].text
+```
+
+To use Canary for transcribing other supported languages or perform Speech-to-Text translation, specify the input as jsonl manifest file, where each line in the file is a dictionary containing the following fields: 
+
+```yaml
+# Example of a line in input_manifest.json
+{
+    "audio_filepath": "/path/to/audio.wav",  # path to the audio file
+    "duration": 1000,  # duration of the audio, can be set to `None` if using NeMo main branch
+    "taskname": "asr",  # use "s2t_translation" for speech-to-text translation with r1.23, or "ast" if using the NeMo main branch
+    "source_lang": "en",  # language of the audio input, set `source_lang`==`target_lang` for ASR, choices=['en','de','es','fr']
+    "target_lang": "en",  # language of the text output, choices=['en','de','es','fr']
+    "pnc": "yes",  # whether to have PnC output, choices=['yes', 'no']
+    "answer": "na", 
+}
+```
+
+and then use:
+```python
+predicted_text = canary_model.transcribe(
+    "<path to input manifest file>",
+    batch_size=16,  # batch size to run the inference with
+)[0].text
+```
+
+
+### Automatic Speech-to-text Recognition (ASR)
+
+An example manifest for transcribing English audios can be:
+
+```yaml
+# Example of a line in input_manifest.json
+{
+    "audio_filepath": "/path/to/audio.wav",  # path to the audio file
+    "duration": 1000,  # duration of the audio, can be set to `None` if using NeMo main branch
+    "taskname": "asr",  
+    "source_lang": "en", # language of the audio input, set `source_lang`==`target_lang` for ASR, choices=['en','de','es','fr']
+    "target_lang": "en", # language of the text output, choices=['en','de','es','fr']
+    "pnc": "yes",  # whether to have PnC output, choices=['yes', 'no']
+    "answer": "na", 
+}
+```
+
+
+### Automatic Speech-to-text Translation (AST)
+
+An example manifest for transcribing English audios into German text can be:
+
+```yaml
+# Example of a line in input_manifest.json
+{
+    "audio_filepath": "/path/to/audio.wav",  # path to the audio file
+    "duration": 1000,  # duration of the audio, can be set to `None` if using NeMo main branch
+    "taskname": "s2t_translation", # r1.23 only recognizes "s2t_translation", but "ast" is supported if using the NeMo main branch
+    "source_lang": "en", # language of the audio input, choices=['en','de','es','fr']
+    "target_lang": "de", # language of the text output, choices=['en','de','es','fr']
+    "pnc": "yes",  # whether to have PnC output, choices=['yes', 'no']
+    "answer": "na" 
+}
+```
+
+Alternatively, one can use `transcribe_speech.py` script to do the same. 
+
+```bash
+python [NEMO_GIT_FOLDER]/examples/asr/transcribe_speech.py 
+ pretrained_name="nvidia/canary-1b" 
+ audio_dir="<path to audio_directory>" # transcribes all the wav files in audio_directory
+```
+
+
+```bash
+python [NEMO_GIT_FOLDER]/examples/asr/transcribe_speech.py 
+ pretrained_name="nvidia/canary-1b" 
+ dataset_manifest="<path to manifest file>" 
+```
+
+
+### Input
+
+This model accepts single channel (mono) audio sampled at 16000 Hz, along with the task/languages/PnC tags as input.
+
+### Output
+
+The model outputs the transcribed/translated text corresponding to the input audio, in the specified target language and with or without punctuation and capitalization.
+
+
+
+## Training
+
+Canary-1B is trained using the  NVIDIA NeMo toolkit [4] for 150k steps with dynamic bucketing and a batch duration of 360s per GPU on 128 NVIDIA A100 80GB GPUs. 
+The model can be trained using this [example script](https://github.com/NVIDIA/NeMo/blob/main/examples/asr/speech_multitask/speech_to_text_aed.py) and [base config](https://github.com/NVIDIA/NeMo/blob/main/examples/asr/conf/speech_multitask/fast-conformer_aed.yaml).
+
+The tokenizers for these models were built using the text transcripts of the train set with this [script](https://github.com/NVIDIA/NeMo/blob/main/scripts/tokenizers/process_asr_text_tokenizer.py).
+
+
+### Datasets

+## Performance
+
+In both ASR and AST experiments, predictions were generated using beam search with width 5 and length penalty 1.0.
+
+### ASR Performance (w/o PnC) 
+
+The ASR performance is measured with word error rate (WER), and we process the groundtruth and predicted text with [whisper-normalizer](https://pypi.org/project/whisper-normalizer/).
+
+WER on [MCV-16.1](https://commonvoice.mozilla.org/en/datasets) test set:
+
+| **Version** | **Model**     | **En**   | **De**   | **Es**   | **Fr**   |
+|:---------:|:-----------:|:------:|:------:|:------:|:------:|
+| 1.23.0  | canary-1b | 7.97 | 4.61 | 3.99 | 6.53 |
+
+
+WER on [MLS](https://huggingface.co/datasets/facebook/multilingual_librispeech) test set:
+
+| **Version** | **Model**     | **En**   | **De**   | **Es**   | **Fr**   |
+|:---------:|:-----------:|:------:|:------:|:------:|:------:|
+| 1.23.0  | canary-1b | 3.06 | 4.19 | 3.15 | 4.12 |
+
+
+More details on evaluation can be found at [HuggingFace ASR Leaderboard](https://huggingface.co/spaces/hf-audio/open_asr_leaderboard)
+
+### AST Performance
+
+We evaluate AST performance with [BLEU score](https://lightning.ai/docs/torchmetrics/stable/text/sacre_bleu_score.html), and use native annotations with punctuation and capitalization in the datasets.
+
+BLEU score on [FLEURS](https://huggingface.co/datasets/google/fleurs) test set:
+
+| **Version** | **Model** | **En->De** | **En->Es** | **En->Fr** | **De->En** | **Es->En** | **Fr->En** |

+
+
+BLEU score on [COVOST-v2](https://github.com/facebookresearch/covost) test set:

+
+## Model Fairness Evaluation
+
+As outlined in the paper "Towards Measuring Fairness in AI: the Casual Conversations Dataset", we assessed the Canary-1B model for fairness. The model was evaluated on the CausalConversations-v1 dataset, and the results are reported as follows:
+
+### Gender Bias:
+
+| Gender | Male | Female | N/A | Other |
+| :--- | :--- | :--- | :--- | :--- |
+| Num utterances | 19325 | 24532 | 926 | 33 |
+| % WER | 14.64 | 12.92 | 17.88 | 126.92 |
+
+### Age Bias:
+
+| Age Group | (18-30) | (31-45) | (46-85) | (1-100) |
+| :--- | :--- | :--- | :--- | :--- |
+| Num utterances | 15956 | 14585 | 13349 | 43890 |
+| % WER | 14.64 | 13.07 | 13.47 | 13.76 |
+
+(Error rates for fairness evaluation are determined by normalizing both the reference and predicted text, similar to the methods used in the evaluations found at https://github.com/huggingface/open_asr_leaderboard.)
