💻 使用範例
範例 1: 基本說話人分離
from pyannote.audio import Pipeline
# 載入預訓練模型
pipeline = Pipeline.from_pretrained("pyannote/speaker-diarization-3.1")
# 執行說話人分離
diarization = pipeline("audio.wav")
# 輸出結果
for turn, _, speaker in diarization.itertracks(yield_label=True):
print(f"[{turn.start:.2f}s - {turn.end:.2f}s] {speaker}")
輸出範例:
[0.00s - 5.32s] SPEAKER_00
[5.50s - 12.18s] SPEAKER_01
[12.50s - 18.75s] SPEAKER_00
[19.00s - 25.43s] SPEAKER_02
範例 2: 自定義參數
from pyannote.audio import Pipeline
# 載入模型時配置參數
pipeline = Pipeline.from_pretrained(
"pyannote/speaker-diarization-3.1",
use_auth_token="hf_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
)
# 配置參數
diarization = pipeline(
"audio.wav",
min_speakers=2, # 最少說話人數
max_speakers=5 # 最多說話人數
)
# 輸出
for turn, _, speaker in diarization.itertracks(yield_label=True):
print(f"[{turn.start:.2f}s - {turn.end:.2f}s] {speaker}")
範例 3: 與 Whisper 整合
import whisper
from pyannote.audio import Pipeline
# 1. ASR 轉錄
whisper_model = whisper.load_model("base")
transcription = whisper_model.transcribe("audio.wav")
# 2. 說話人分離
diarization_pipeline = Pipeline.from_pretrained(
"pyannote/speaker-diarization-3.1"
)
diarization = diarization_pipeline("audio.wav")
# 3. 整合結果
diarization_segments = []
for turn, _, speaker in diarization.itertracks(yield_label=True):
diarization_segments.append({
"start": turn.start,
"end": turn.end,
"speaker": speaker
})
# 4. 匹配說話人到轉錄
for segment in transcription["segments"]:
# 找到重疊的說話人
for spk_seg in diarization_segments:
if segment["start"] < spk_seg["end"] and segment["end"] > spk_seg["start"]:
print(f"[{spk_seg['speaker']}] {segment['text']}")
break
輸出範例:
[SPEAKER_00] 你好,歡迎來到今天的會議。
[SPEAKER_01] 謝謝,我想先討論一下第一季度的業績。
[SPEAKER_00] 好的,請說。
[SPEAKER_02] 我這邊有個問題...
範例 4: 批次處理
from pyannote.audio import Pipeline
from pathlib import Path
# 載入模型
pipeline = Pipeline.from_pretrained("pyannote/speaker-diarization-3.1")
# 批次處理多個檔案
audio_files = list(Path("audio_folder").glob("*.wav"))
for audio_file in audio_files:
print(f"Processing {audio_file.name}...")
diarization = pipeline(str(audio_file))
# 儲存結果
output = {
"file": audio_file.name,
"speakers": []
}
for turn, _, speaker in diarization.itertracks(yield_label=True):
output["speakers"].append({
"start": turn.start,
"end": turn.end,
"speaker": speaker
})
# 儲存為 JSON
import json
with open(f"{audio_file.stem}_diarization.json", "w") as f:
json.dump(output, f, indent=2)

🔍 進階功能
1. 語音活動檢測(VAD)
from pyannote.audio import Model
from pyannote.audio.core.io import Audio
# 載入 VAD 模型
vad_model = Model.from_pretrained("pyannote/segmentation-3.0")
# 檢測語音
audio = Audio()
segments = vad_model(str(audio_file))
for segment in segments:
print(f"Speech: {segment.start:.2f}s - {segment.end:.2f}s")
2. 說話人驗證
from pyannote.audio import Inference
from pyannote.audio.pipelines import SpeakerVerification
# 載入說話人驗證模型
verification = SpeakerVerification.from_pretrained(
"pyannote/speaker-verification-3.0"
)
# 驗證兩個音頻是否為同一人
score = verification(
{"uri": "file1", "audio": "speaker1.wav"},
{"uri": "file2", "audio": "speaker2.wav"}
)
if score > 0.5:
print("同一人")
else:
print("不同人")
3. 自定義模型微調
from pyannote.audio import Model
# 微調預訓練模型
model = Model.from_pretrained("pyannote/speaker-diarization-3.1")
# 準備自定義數據集
# (需要 pyannote.database 配置)
# 開始微調
# (詳細步驟參考官方文檔)
⚠️ 常見問題
Q1: Token 錯誤
錯誤訊息:
OSError: You need to provide a valid token to access this model.
解決方案:
# 確認 token 已正確配置
huggingface-cli whoami
# 如果未登入,重新登入
huggingface-cli login
# 或手動設置環境變數
export HUGGING_FACE_HUB_TOKEN="hf_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
Q2: PyTorch 版本問題
錯誤訊息:
ValueError: Due to a serious vulnerability issue in `torch.load`...
解決方案:
# 升級 PyTorch 到 2.6+
pip install torch==2.6.0 torchaudio==2.6.0
# 或設置環境變數(不推薦,僅測試用)
export TORCH_FORCE_WEIGHTS_ONLY_LOAD=0
Q3: 記憶體不足
錯誤訊息:
RuntimeError: CUDA out of memory
解決方案:
# 使用 CPU 而非 GPU
pipeline = Pipeline.from_pretrained(
"pyannote/speaker-diarization-3.1"
)
pipeline.to(torch.device("cpu"))
# 或減少批次大小
diarization = pipeline(
"audio.wav",
batch_size=16 # 減少為 8 或 4
)
Q4: 準確度不佳
可能原因:
- 音頻品質差
- 背景噪音大
- 說話人太多(>6 人)
- 重疊說話
解決方案:
# 1. 指定說話人數量範圍
diarization = pipeline(
"audio.wav",
min_speakers=2,
max_speakers=4
)
# 2. 調整閾值
diarization = pipeline(
"audio.wav",
threshold=0.5 # 預設 0.5,可調整為 0.3-0.7
)
# 3. 使用更好的模型
pipeline = Pipeline.from_pretrained(
"pyannote/speaker-diarization-3.1" # 最新版本
)
