Utilities managing the pretrained models created by ESPnet. This function is inspired by the Asteroid pretrained model function.
- From version 0.1.0, the huggingface models can be also used: https://huggingface.co/models?filter=espnet
- Zenodo community: https://zenodo.org/communities/espnet/
- Registered models: table.csv
pip install torch
pip install espnet_model_zoo
model_name in the following section should be huggingface_id or one of the tags in the table.csv.
Or you can directly provide zenodo URL (e.g., https://zenodo.org/record/xxxxxxx/files/hogehoge.zip?download=1).

# If not, you need to resample the audio data before inputting to speech2text
speech, rate = soundfile.read("long_speech.wav")
waves = separate_speech(speech[None, ...], fs=rate)This API allows processing both short audio samples and long audio samples. For long audio samples, you can set the value of arguments segment_size, hop_size (optionally normalize_segment_scale and show_progressbar) to perform segment-wise speech enhancement/separation on the input speech. Note that the segment-wise processing is disabled by default.

d = ModelDownloader("~/.cache/espnet") # Specify cachedir

>>> d.download_and_unpack("kamo-naoyuki/mini_an4_asr_train_raw_bpe_valid.acc.best")
{"asr_train_config": <config path>, "asr_model_file": <model path>, ...}You can specify the revision if it's huggingface_id giving with @:
>>> d.download_and_unpack("kamo-naoyuki/mini_an4_asr_train_raw_bpe_valid.acc.best@<revision>")
{"asr_train_config": <config path>, "asr_model_file": <model path>, ...}Note that if the model already exists, you can skip downloading and unpacking.
You can also get a model with certain conditions.
d.download_and_unpack(task="asr", corpus="wsj")If multiple models are found with the condition, the last model is selected. You can also specify the condition using "version" option.
d.download_and_unpack(task="asr", corpus="wsj", version=-1) # Get the last model
d.download_and_unpack(task="asr", corpus="wsj", version=-2) # Get previous modelYou can also obtain it from the URL directly.
d.download_and_unpack("https://zenodo.org/record/...")If you need to use a local model file using this API, you can also give it.
d.download_and_unpack("./some/where/model.zip")In this case, the contents are also expanded in the cache directory, but the model is identified by the file path, so if you move the model to somewhere and unpack again, it's treated as another model, thus the contents are expanded again at another place.
You can view the model names from our Zenodo community, https://zenodo.org/communities/espnet/,
or using query(). All information are written in table.csv.
d.query("name")You can also show them with specifying certain conditions.
d.query("name", task="asr")-
espnet_model_zoo_query# Query model name espnet_model_zoo_query task=asr corpus=wsj # Show all model name espnet_model_zoo_query # Query the other key espnet_model_zoo_query --key url task=asr corpus=wsj

Upload your model using huggingface API
- (if you do not have an HF hub account) Go to https://huggingface.co and create an HF account by clicking a
sign upbutton below.
- From a new model link in the profile, create a new model repository. Please include a recipe name (e.g., aidatatang_200zh) and model info (e.g., conformer) in the repository name
- In the espnet recipe, execute the following command:
./run.sh --stage 15 --skip_upload_hf false --hf_repo sw005320/aidatatang_200zh_conformer- Please follow the instruction (e.g., type the HF Username/Password)
- If it works successfully, you can get the following messages

Create a Pull Request to modify table.csv
The model can be registered in table.csv. Then, the model will be tested in the CI. Note that, unlike the zenodo case, you don't need to add the URL because huggingface_id itself can specify the model file, so please fill the value as
https://huggingface.co/.e.g.
table.csv... aidatatang_200zh,asr,sw005320/aidatatang_200zh_conformer,https://huggingface.co/,16000,zh,,,,,true -

Upload your model to Zenodo
You need to signup to Zenodo and create an access token to upload models. You can upload your own model by using
espnet_model_zoo_uploadcommand freely, but we normally upload a model using recipes. -
