Model description

Intended uses & limitations

Transcribe files in Dutch:

import soundfile as sf
from transformers import pipeline

whisper_asr = pipeline("automatic-speech-recognition", model="qmeeus/whisper-small-nl", device=0)
whisper_asr.model.config.forced_decoder_ids = whisper_asr.tokenizer.get_decoder_prompt_ids(
    task="transcribe", language="nl"
)

waveform, sr = sf.read(filename)

def iter_chunks(waveform, sampling_rate=16_000, chunk_length=30.):
    assert sampling_rate == 16_000
    n_frames = math.floor(sampling_rate * chunk_length)
    for start in range(0, len(waveform), n_frames):
        end = min(len(waveform), start + n_frames)
        yield waveform[start:end]

for sentence in whisper_asr(iter_chunks(waveform, sr), max_new_tokens=448):
    print(sentence["text"])
