注意：您需要安裝Pydub才能pip使上述代碼正常工作。

上述函數(shù)使用模塊split_on_silence()中的函數(shù)pydub.silence在靜音時(shí)將音頻數(shù)據(jù)分割成塊。該min_silence_len參數(shù)是用于分割的最小靜音長度（以毫秒為單位）。

silence_thresh是閾值，任何比這更安靜的東西都將被視為靜音，我將其設(shè)置為平均dBFS - 14，keep_silence參數(shù)是在檢測到的每個塊的開頭和結(jié)尾處留下的靜音量（以毫秒為單位）。

這些參數(shù)并不適合所有聲音文件，請嘗試根據(jù)您的大量音頻需求嘗試這些參數(shù)。

之后，我們迭代所有塊并將每個語音音頻轉(zhuǎn)換為文本，然后將它們加在一起，這是一個運(yùn)行示例：

path = "7601-291468-0006.wav"
print("\nFull text:", get_large_audio_transcription_on_silence(path))
注意：您可以在此處7601-291468-0006.wav獲取文件。
