🔧 Installation & Usage

Installation

pip install faster-whisper

Basic Usage

from faster_whisper import WhisperModel

# Load the model
model = WhisperModel("2snem6/faster-whisper-large-v3-edacc-commonvoice-l2arctic-v3")

# Transcribe audio
segments, info = model.transcribe("audio.wav")

print(f"Detected language: {info.language} (probability: {info.language_probability:.2f})")

for segment in segments:
    print(f"[{segment.start:.2f}s -> {segment.end:.2f}s] {segment.text}")

Advanced Usage

# With custom parameters
segments, info = model.transcribe(
    "audio.wav",
    beam_size=5,
    language="en",  # Force English
    condition_on_previous_text=False,
    temperature=0.0
)

# Batch processing
audio_files = ["file1.wav", "file2.wav", "file3.wav"]
for audio_file in audio_files:
    segments, info = model.transcribe(audio_file)
    # Process segments...

Loading from Local Path

# If you've downloaded the model locally
model = WhisperModel("/path/to/downloaded/model")
