Fongbe ASR model with diacritics

How to use for inference

from speechbrain.inference.ASR import EncoderASR

asr_model = EncoderASR.from_hparams(
    source="whettenr/asr-fon-with-diacritics",
    savedir="pretrained_models/asr-fongbe-with-diacritics"
)

asr_model.transcribe_file("whettenr/asr-fon-with-diacritics/example.wav")

# expected output:
# huzuhuzu gɔngɔn ɖé ɖò dandan
