谷歌语音api被禁止

Question

Hey Guys I am working on google speech api using python speech recognition model. I have tried using the default api along with them and it works. But when I try to use it along with my api. I am getting the following error:

Could not request results from Google Speech Recognition service; recognition request failed: Forbidden

And this is my code

import speech_recognition as sr
from os import path
AUDIO_FILE = path.join(path.dirname(path.realpath(__file__)), "file.wav")

r = sr.Recognizer()
with sr.AudioFile(AUDIO_FILE) as source:
    audio = r.record(source) # read the entire audio file
try:
# for testing purposes, we're just using the default API key
# to use another API key, use `r.recognize_google(audio, key="GOOGLE_SPEECH_RECOGNITION_API_KEY")`
# instead of `r.recognize_google(audio)`
print("Google Speech Recognition thinks you said " + r.recognize_google(audio, key="AIzaSyAqwPcs_F6cyNltsrZPGRQKRFakDX3d85"))
except sr.UnknownValueError:
   print("Google Speech Recognition could not understand audio")
except sr.RequestError as e:
   print("Could not request results from Google Speech Recognition   service; {0}".format(e))

Any kind of help is appreciated.

Answer 1

I suggest first set your credentials as a local variable:

export GOOGLE_APPLICATION_CREDENTIALS='/home/user/Documents/your_credentials.json'

Details here: https://cloud.google.com/docs/authentication/getting-started

Then this could help for long .wav transcripts: https://cloud.google.com/speech-to-text/docs/async-recognize?hl=es

The language is defined by 'en-US' for example for english US. See here the complete list https://cloud.google.com/speech-to-text/docs/languages?hl=es

notice that when you use googles speech recognition API without a key, the speech recognition module will use a default key. However Google can reject that request at any time. In that case you will get the error recognition request failed: Forbidden . This will also happen if you use a wrong key. Quote from the module at __init__.py at line 810:

Performs speech recognition on audio_data (an AudioData instance), using the Google Speech Recognition API. The Google Speech Recognition API key is specified by key . If not specified, it uses a generic key that works out of the box. This should generally be used for personal or testing purposes only, as it may be revoked by Google at any time . To obtain your own API key, simply following the steps on the API Keys <http://www.chromium.org/developers/how-tos/api-keys> __ page at the Chromium Developers site. In the Google Developers Console, Google Speech Recognition is listed as "Speech API".

Just either get yourself a key or if you really don't want to then use the inbuilt recognize_sphynx(audio) or the snowboy.
