# Pruned Stateless Zipformer RNN-T Streaming Robust ES v0

Pruned Stateless Zipformer RNN-T Streaming Robust ES v0 is a Spanish automatic speech recognition model trained on the following datasets:

- [Common Voice 23.0 Spanish](https://datacollective.mozillafoundation.org/datasets/cmflnuzw51ddgmwjkxpm9z1lw)
- [SLR72 dataset](https://www.openslr.org/72/)

Instead of being trained to predict sequences of words, this model was trained to predict sequence of phonemes, e.g. `["w", "ɑ", "ʃ", "i", "ɑ"]`. Therefore, the model's [vocabulary](https://huggingface.co/bookbot/zipformer-streaming-robust-es-v0/blob/main/data/lang_phone/tokens.txt) contains the different IPA phonemes found in [gruut](https://github.com/rhasspy/gruut).

This model was converted from the TorchScript version of [Pruned Stateless Zipformer RNN-T Streaming Robust ES](https://huggingface.co/bookbot/zipformer-streaming-robust-es-v0) to ONNX format.


## Converting from TorchScript

Refer to the [official instructions](https://icefall.readthedocs.io/en/latest/model-export/export-onnx.html#export-the-model-to-onnx) for conversion to ONNX.
