pyannote.audio // 说话人分割

该模型来自论文《端到端说话人分割用于重叠感知的重分割》，
作者为Hervé Bredin和Antoine Laurent。

依赖正在开发中的pyannote.audio 2.0版本：请参阅安装说明。

使用

语音活动检测

from pyannote.audio.pipelines import VoiceActivityDetection
pipeline = VoiceActivityDetection(segmentation="pyannote/segmentation")
HYPER_PARAMETERS = {
  # 开始/结束激活阈值
  "onset": 0.5, "offset": 0.5,
  # 移除短于此秒数的语音区域。
  "min_duration_on": 0.0,
  # 填充短于此秒数的非语音区域。
  "min_duration_off": 0.0
}
pipeline.instantiate(HYPER_PARAMETERS)
vad = pipeline("audio.wav")
# `vad`是一个包含语音区域的pyannote.core.Annotation实例

重叠语音检测

from pyannote.audio.pipelines import OverlappedSpeechDetection
pipeline = OverlappedSpeechDetection(segmentation="pyannote/segmentation")
pipeline.instantiate(HYPER_PARAMETERS)
osd = pipeline("audio.wav")
# `osd`是一个包含重叠语音区域的pyannote.core.Annotation实例

重分割

from pyannote.audio.pipelines import Resegmentation
pipeline = Resegmentation(segmentation="pyannote/segmentation", 
                          diarization="baseline")
pipeline.instantiate(HYPER_PARAMETERS)
resegmented_baseline = pipeline({"audio": "audio.wav", "baseline": baseline})
# 其中`baseline`应作为pyannote.core.Annotation实例提供

原始分数

from pyannote.audio import Inference
inference = Inference("pyannote/segmentation")
segmentation = inference("audio.wav")
# `segmentation`是一个pyannote.core.SlidingWindowFeature
# 实例，包含原始分割分数，如上图所示（输出）
