SpeechRecognition не отвечает, если я использую живой микрофон.
Я успешно установил библиотеку SpeechRecognition и PyAudio с помощью python3 -m pip install ... Я работаю над Raspberry Pi Zero в виртуальной среде с помощью: Python 3.7.3 pip 21.0.1
Я использую микрофонный выход Adafruit I2S MEMS и могу успешно записывать, используя:
arecord -D plughw:1 -c1 -r 48000 -f S32_LE -t wav -V mono -v file.wav
Когда я сохраняю это в файле (file.wav) и использую следующий код, распознаватель речи работает:
import speech_recognition as sr
r = sr.Recognizer()
with sr.AudioFile('file.wav') as source:
audio = r.record(source)
try:
print("You said: " + r.recognize_google(audio))
except sr.UnknowValueError:
print("Sorry, could not understand audio")
except sr.RequestError as e:
print("Could not request results from Google Speech Recognition service; {0}".format(e))
Но когда я хочу выполнить распознавание живой речи с помощью следующего кода:
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone(1) as source:
print("Say something!")
audio = r.listen(source)
try:
print("You said: " + r.recognize_google(audio))
except sr.UnknowValueError:
print("Sorry, could not understand audio")
except sr.RequestError as e:
print("Could not request results from Google Speech Recognition service; {0}".format(e))
Он дает следующий результат и постоянно говорит: «Скажи что-нибудь», не показывая стенограммы:

Say something!
Когда я нажимаю ^ C через некоторое время, потому что ничего не происходит, добавляется следующий бит:

Пожалуйста, дайте мне знать, если потребуется дополнительная информация. Я надеюсь, что найдется кто-то действительно умный, который сможет мне помочь, заранее спасибо!
Новый код после первого ответа:
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone(1) as source:
print("Say something!")
audio = r.listen(source)
data = ""
try:
data = r.recognize_google(audio)
print("You said: " + data)
except sr.UnknownValueError:
print("Sorry, could not understand audio")
except sr.RequestError as e:
print("Could not request results from Google Speech Recognition service; {0}".format(e))
return data
Ошибка выдачи этого возврата вне функции.
