TheWhisper-Large-V3-Turbo

Model Summary

TheWhisper-Large-V3-Turbo is a fine-tuned, high-performance variant of OpenAI’s Whisper Large V3 model — optimized by TheStage AI for real-time, low-latency, and low-power speech-to-text (ASR) inference across multiple platforms, including NVIDIA GPUs and Apple Silicon (CoreML).

It provides streaming transcription, word timestamps, and scalable performance for use cases like real-time captioning, meetings, and on-device voice interfaces.

📊 Quality Benchmarks

TheWhisper is a fine-tuned Whisper model that can process audio chunks of any size up to 30 seconds. Unlike the original Whisper models, it doesn't require padding audio with silence to reach 30 seconds. We conducted quality benchmarking across different chunk sizes: 10, 15, 20, and 30 seconds. For quality benchmarks, we used the multilingual benchmarks Open ASR Leaderboard.

    # Optimized model by ANNA
    model_size='S',
    # Window length
    chunk_length_s=10,
    platform='apple'
)

# set stride in miliseconds
mic_stream = MicStream(step_size_s=0.5)
output_stream = StdoutStream()

while True:
    chunk = mic_stream.next_chunk()
    if chunk:
        approved_text, assumption = streaming_pipe(chunk)
        output_stream.rewrite(approved_text, assumption)
    else:
        break
