ESPNet2 ASR Librispeech Conformer (100h) is a kit in the Research category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-13. Download it on this page, a zip of its files. Nothing in it runs by itself. Made by jkang ## About ### What it is This Gradio app is a demo of English speech recognition. By its name it runs an ESPnet2 Conformer model trained on 100 hours of Librispeech. The record names one model from the same author, and the repository holds an examples folder with sample audio. ### Who it suits It suits speech researchers and students who want to try a Conformer recognizer without setting up code, and developers who want a small ESPnet2 demo to read. The record gives no accuracy figures, so judge results by listening. | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Research | Speech researchers | Try a Conformer model on English audio | Run an example clip and read the transcript | | Education | Students of speech technology | See what a model trained on limited data produces | Compare the text with what you hear | | Software | Python developers | Read a Gradio wrapper around an ESPnet2 model | Open the main file and packages.txt | You can skip it if your audio is not in English. ### Where to use it - A web browser, on the Space's page on Hugging Face - Windows, macOS or Linux with Python, from a downloaded copy | Use case | Who | What they get back | | --- | --- | --- | | Transcribe English audio | Researchers and students | Text from the Conformer model | | Try the bundled examples | Anyone | A quick sense of what the model hears | | Study the wrapper | Developers | A short Gradio script around an ESPnet2 model | ### How to set it up - Nothing at all if you use the online Space - Python on your computer, only if you run a copy - The packages listed in requirements.txt - System packages from packages.txt, which Hugging Face installs with apt-get 1. Open the Space's page in a browser to use it with nothing to install. 2. To run a copy, install the Hugging Face Hub package and download the Space. 3. Move into the new folder, then install Gradio and the listed requirements. 4. Start the app with Python, using its main file gradio\_asr\_en\_libri100.py. ```sh pip install -U huggingface_hub hf download jkang/espnet2_asr_librispeech_100h --repo-type space --local-dir espnet2_asr_librispeech_100h cd espnet2_asr_librispeech_100h pip install gradio pip install -r requirements.txt python gradio_asr_en_libri100.py ``` ### How to use it Online, open the Space and use the controls on its page. On your own machine, run the main file from the Space folder, then use the page it serves. The example audio files are the quickest way to try it. ```sh python gradio_asr_en_libri100.py ``` ### Example You open the Space and run it on one of the example audio clips. The app returns the English text the model hears in the clip. The record does not describe the controls, so check the page. ### For newcomers and experts Speech recognition means a program listens and writes down what it hears. Start by opening the Space and running one of the example clips. If you know the field, the model is a Conformer trained on a 100 hour slice of Librispeech, which is a modest slice of that corpus. The record gives no error rates, so measure on your own audio. You choose an example or give audio → The Gradio page sends it to the script → The ESPnet2 Conformer model decodes it → The page shows the English text ### Good to know - License: MIT, as listed on the Space - Cost to run: none named - Data it reaches: the audio you give it, the model it names and the example clips - Not for: non-English speech, since the model is named for English ## README ````markdown # ESPNet2 ASR Librispeech Conformer (100h) Transcribes English speech to text with an ESPnet2 Conformer model trained on 100 hours of Librispeech, in a Gradio page with example audio.
