ChunkFormer Model

Usage

Install the package:

pip install chunkformer

python

from chunkformer import ChunkFormerModel

# Load the model
model = ChunkFormerModel.from_pretrained("khanhld/chunkFormer-ctc-small-libri-960h")

# For long-form audio transcription
transcription = model.endless_decode(
    audio_path="path/to/your/audio.wav",
    chunk_size=64,
    left_context_size=128,
    right_context_size=128,
    return_timestamps=True
)
print(transcription)

# For batch processing
audio_files = ["audio1.wav", "audio2.wav", "audio3.wav"]
transcriptions = model.batch_decode(
    audio_paths=audio_files,
    chunk_size=64,
    left_context_size=128,
    right_context_size=128
)
