Usage

Loading the Dataset

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("thucdangvan020999/singaporean_district_noise_snr_2_7")

# Access the data
for sample in dataset['train']:
    audio_array = sample['audio']['array']
    sampling_rate = sample['audio']['sampling_rate'] 
    text = sample['text']
    
    # Your processing code here
    print(f"Audio shape: {audio_array.shape}")
    print(f"Text: {text}")

Example Usage with Transformers

from datasets import load_dataset
from transformers import WhisperProcessor, WhisperForConditionalGeneration

# Load dataset and model
dataset = load_dataset("thucdangvan020999/singaporean_district_noise_snr_2_7")
processor = WhisperProcessor.from_pretrained("openai/whisper-small")
model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-small")

# Process a sample
sample = dataset['train'][0]
inputs = processor(
    sample['audio']['array'], 
    sampling_rate=sample['audio']['sampling_rate'], 
    return_tensors="pt"
)

# Generate transcription
with torch.no_grad():
    predicted_ids = model.generate(inputs["input_features"])
    transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)
