通过 Sphinx 引擎进行语音识别会产生 AttributeError: 'NoneType' object has no attribute 'close'

问题描述

我正在尝试使用以下代码转录视频，但收到以下错误：

ERROR : transcribe_video_to_text
    audio.close()

AttributeError: 'NoneType' object has no attribute 'close'

您能否分享您解决这个问题的想法，或者建议可以执行转录的替代库或 AI？

代码：

import moviepy.editor as mp
import speech_recognition as sr

def transcribe_video_to_text(video_path):
    # Extract audio from the video
    video = mp.VideoFileClip(video_path)
    audio = video.audio.write_audiofile("temp_audio.wav")

    # Initialize the speech recognition object
    recognizer = sr.Recognizer()

    # Read the audio file
    with sr.AudioFile("temp_audio.wav") as source:
        audio_data = recognizer.record(source)

    # Perform speech recognition on the audio
    text = recognizer.recognize_sphinx(audio_data, keyword_entries=[('whisper', 1.0)])

    # Remove the temporary audio file
    video.close()
    audio.close()
    os.remove("temp_audio.wav")

    return text

# Provide the path to your video file
video_path = "Gods Architect Antoni Gaudis glorious vision.mp4"

# Transcribe the video to text
transcription = transcribe_video_to_text(video_path)

# Print the resulting transcription
print("Video transcription:")
print(transcription)
