How to Get Started with the Model
Use the code below to get started with the model.
from transformers import (
AutomaticSpeechRecognitionPipeline,
WhisperForConditionalGeneration,
WhisperTokenizer,
WhisperProcessor,
)
from peft import PeftModel, PeftConfig
peft_model_id = "baileyarzate/whisper-distil-large-v3-atc-english" # huggingface model path
language = "en"
task = "transcribe"
device = 'cuda'
peft_config = PeftConfig.from_pretrained(peft_model_id)
model = WhisperForConditionalGeneration.from_pretrained(
peft_config.base_model_name_or_path, device_map="cuda"
).to(device)
model = PeftModel.from_pretrained(model, peft_model_id).to(device)
tokenizer = WhisperTokenizer.from_pretrained(peft_config.base_model_name_or_path, language=language, task=task)
processor = WhisperProcessor.from_pretrained(peft_config.base_model_name_or_path, language=language, task=task)
feature_extractor = processor.feature_extractor
forced_decoder_ids = processor.get_decoder_prompt_ids(language=language, task=task)
pipe = AutomaticSpeechRecognitionPipeline(model=model, tokenizer=tokenizer, feature_extractor=feature_extractor)
model.config.use_cache = True
def transcribe(audio):
with torch.cuda.amp.autocast():
text = pipe(audio, generate_kwargs={"forced_decoder_ids": forced_decoder_ids}, max_new_tokens=255)["text"]
return text
transcriptions_finetuned = []
for i in tqdm(range(len(df_subset))):
# When you only have audio file path
#transcriptions_finetuned.append(transcribe(librosa.load(df["path"][i], sr = 16000, offset = df["start"][i], duration = df["stop"][i] - df["start"][i])[0])) #,model
# When you have audio array, saves time
transcriptions_finetuned.append(transcribe(df_subset['array'].iloc[i]))
transcriptions_finetuned = pd.DataFrame(transcriptions_finetuned, columns=['transcription_finetuned'])
df_subset = df_subset.reset_index().drop(columns=['index'])
df_subset = pd.concat([df_subset, transcriptions_finetuned], axis=1)
Training Details
Training Data
Dataset: ATC audio recordings from actual flight operations. Size: ~250 hours of annotated data.
Training Procedure
Modeled the procedure after: https://github.com/Vaibhavs10/fast-whisper-finetuning
Preprocessing [optional]
Preprocessing: Striped leading and trailing whitespaces from transcript sentences. Removed any sentences containing the phrase "UNINTELLIGIBLE" to filter out unclear or garbled speech. Removed filler words such as "ah" or "uh".
Training Hyperparameters
- Training regime: [More Information Needed]
training_args = Seq2SeqTrainingArguments(
per_device_train_batch_size=4,
gradient_accumulation_steps=2,
learning_rate=5e-4,
warmup_steps=100,
num_train_epochs=3,
fp16=True,
per_device_eval_batch_size=4,
generation_max_length=128,
logging_steps=100,
save_steps=500,
save_total_limit=3,
remove_unused_columns=False, # required as the PeftModel forward doesn't have the signature of the wrapped model's forward
label_names=["labels"], # same reason as above
)
Speeds, Sizes, Times [optional]
Inference time is about 2 samples per second with an RTX A2000.
Evaluation
Final training loss: 0.103
Testing Data, Factors & Metrics
Testing Data
Dataset: ATC audio recordings from actual flight operations. Size: ~250 hours of annotated data. Randomly sampled 20% of the data with seed = 42.
