循环崩溃在speech_recognition上

Question

Python Newbie试图教自己如何使用Python运行Secempon_recognition，而我并没有好运。

下面的代码运行一次，并正确将WAV文件转换为文本，但随后在我的S3存储桶中运行其余2个WAV文件之前崩溃了。文件绝对存在：

OSR_US_000_0010_8K.WAV
OSR_US_000_0011_8K.WAV
OSR_US_000_0012_8K.WAV

我可以对其进行一些帮助。

提前致谢。

import boto3

import speech_recognition as sr

r = sr.Recognizer()

session = boto3.client('s3',

                    aws_access_key_id= XXXX,

                    aws_secret_access_key=XXXX,

                    region_name='XXXX')

my_bucket = s3.Bucket(mys3bucket)

for my_bucket_object in my_bucket.objects.all():

    with sr.AudioFile(my_bucket_object.key) as source:

        print(my_bucket_object.key)

        audio_data = r.record(source)

        text = r.recognize_google(audio_data)

        print(text)
