speech recognition - if "confidence" in actual_result["alternative"] error while using speech_recognition in python

Question

I am using speech_recognition my .wav is 34 minutes. I ran for 100 secondes and the result is good. My code is the following

import speech_recognition as sr
r = sr.Recognizer()
audio = sr.AudioFile("xxxx.wav")
with audio as source:
    audio = r.record(source, duration=100)
r.recognize_google(audio, language="fr-FR")

When I run the same code from the begining with duration = 300, I have the following:

---------------------------------------------------------------------------
UnknownValueError                         Traceback (most recent call last)
<ipython-input-4-54e2464499c7> in <module>
----> 1 r.recognize_google(audio, language="fr-FR")

~anaconda3envsenv38libsite-packagesspeech_recognition\__init__.py in recognize_google(self, audio_data, key, language, show_all)
    778         # return results
    779         if show_all: return actual_result
--> 780         if not isinstance(actual_result, dict) or len(actual_result.get("alternative", [])) == 0: raise UnknownValueError()
    781 
    782         if "confidence" in actual_result["alternative"]:

UnknownValueError:
