German ASR

This model is trained on the Mozilla Common Voice 8.0, the Spoken Wikipedia Corpus and the m-ailabs corpus. In contrast to our first model this one can transcribe German Umlauts. Additionally it was trained on a newer Version of the Mozilla Common Voice.

We do not provide a language model.

Performance

This model has a WER of 7.09% and is slightly better then the model from our paper: https://huggingface.co/jfreiwa/asr-crdnn-german

Model application

Install SpeechBrain

First of all, please install SpeechBrain with the following command:

pip install speechbrain

Please notice that we encourage you to read the tutorials and learn more about SpeechBrain.

Using the model

from speechbrain.pretrained import EncoderDecoderASR

asr_model = EncoderDecoderASR.from_hparams(source="jfreiwa/asr-crdnn-german-umlaute", savedir="pretrained_models/asr-crdnn-german-umlaute")
asr_model.transcribe_file("jfreiwa/asr-crdnn-german/example-de.wav")

Inference on GPU

To perform inference on the GPU, add run_opts={"device":"cuda"} when calling the from_hparams method.

Limitations

We do not provide any warranty on the performance achieved by this model when used on other datasets.
