Model description
See facebook/wav2vec2-large-xlsr-53.
Intended uses & limitations
Speech recognition for Esperanto. The base model was pretrained and finetuned on 16kHz sampled speech audio. When using the model make sure that your speech input is also sampled at 16KHz.
Training and evaluation data
The training split was set to train[:15000] while the eval split was set to validation[:1500].
Training procedure
I used run_speech_recognition_ctc.py with the following train.json file passed to it:
{
"dataset_name": "mozilla-foundation/common_voice_13_0",
"model_name_or_path": "facebook/wav2vec2-large-xlsr-53",

},

}
I went through the dataset to find non-speech characters, and these were placed in chars_to_ignore. In addition, there were character sequences that could be transcribed to Esperanto phonemes, and these were placed as a dictionary in chars_to_substitute. This required adding such an argument to the program:
def dict_field(default=None, metadata=None):
return field(default_factory=lambda: default, metadata=metadata)
@dataclass
class DataTrainingArguments:
...
chars_to_substitute: Optional[Dict[str, str]] = dict_field(
default=None,
metadata={"help": "A dict of characters to replace."},
)
Then I copied remove_special_characters to do the actual substitution:
def remove_special_characters(batch):
text = batch[text_column_name]
if chars_to_ignore_regex is not None:
text = re.sub(chars_to_ignore_regex, "", batch[text_column_name])
batch["target_text"] = text.lower() + " "
return batch
def substitute_characters(batch):
text: str = batch["target_text"]
if data_args.chars_to_substitute is not None:
for k, v in data_args.chars_to_substitute.items():
text.replace(k, v)
batch["target_text"] = text.lower()
return batch
with training_args.main_process_first(desc="dataset map special characters removal"):
raw_datasets = raw_datasets.map(
remove_special_characters,
remove_columns=[text_column_name],
desc="remove special characters from datasets",
)
with training_args.main_process_first(desc="dataset map special characters substitute"):
raw_datasets = raw_datasets.map(
substitute_characters,
desc="substitute special characters in datasets",
)

The following hyperparameters were used during training:
- learning_rate: 3e-05
- train_batch_size: 8
- eval_batch_size: 8

Discussion
Nans and Infs
While debugging other training sessions where more data from the Esperanto Common Voice dataset was used -- some loss calculations were returning either inf or nan -- I found that some of the training set trained with this model had surprisingly high CER. Some examples:

Some examples have no audio. All of these files in the dataset are completely useless, and should be removed from the training set.
You can see that the model is trying to hallucinate the target when there's little or no audio. This is terrible for realistically reporting what was said. I'd also hope that there is some measure of certainty, and maybe only go with transcriptions that have relatively high certainty. However, I can't find how to get at a certainty value.
The Common Voice dataset also contains upvotes and downvotes. Of the high CER sentences above, all had 2 upvotes, with some having 0 downvotes, and some having 1. So we cannot rely on upvotes or downvotes to detect quality.
So what to do?
Alternative 1
Despite these zero- and low-quality files, training seems to work OK. However, we still need to address when loss becomes nan or inf because that ruins the calculation.
By running run_speech_recognition_ctc with do_train=false, setting model_name_or_path="xekri/wav2vec2-common_voice_13_0-eo-3", setting eval_split_name to either test, validation, or train, and also modifying trainer.py as follows, I can check if any losses are nan or inf:
# To be JSON-serializable, we need to remove numpy types or zero-d tensors
metrics = denumpify_detensorize(metrics)
if all_losses is not None:
loss_nan = np.where(np.isnan(all_losses))
if len(loss_nan) != 0:
print(f'LOSSES ARE NAN: {loss_nan}')
loss_inf = np.where(np.isinf(all_losses))
if len(loss_inf) != 0:
print(f'LOSSES ARE INF: {loss_inf}')
metrics[f"{metric_key_prefix}_loss"] = all_losses.mean().item()
Doing this shows that of the 14913 examples in test, the following example results in inf loss:
common_voice_eo_25167318.mp3
The audio on this is severly garbled. This should absolutely be filtered out of the test set.
No validation samples result in inf or nan.
The following 18 out of 143984 examples in train result in inf loss:
common_voice_eo_25467641.mp3
common_voice_eo_25467723.mp3
common_voice_eo_25467791.mp3

common_voice_eo_25517673.mp3
common_voice_eo_25517677.mp3
common_voice_eo_25527739.mp3
Those files have no audio.
Alternative 2
Another possibility is just to go through the audio files and throw away any where the peak audio isn't above some threshold.
Alternative 3
Since this model seems to work well enough, I could run inference on all samples, and just discard the ones where the CER (as determined by this model) is too high, say above 0.5. Then use that to filter the examples and train another model. These high-CER examples are:

Note on two of the examples: We know that saluton kiel vi fartas ("Hello, how are you") and atendu momenton ("Wait a moment") is a good start in learning Esperanto, but if that's not the text to record, you're not really helping.

I didn't include some which had high CER because of hallucinations during a one-word recording with lots of silence before and after. The recording itself is fine on these.
Training set
135 of 143984 examples yielded high CER. I removed some from this list that had high CER but sounded fine.
