cloudspeech_demo.py fails: AttributeError: module 'google.cloud.speech' has no attribute 'types'

[bbrendon]

I tried doing a git pull to get possibly updated but that didn't change anything. Any ideas?

pi@raspberrypi:~/AIY-projects-python/src/examples/voice $ ./cloudspeech_demo.py
Traceback (most recent call last):
  File "./cloudspeech_demo.py", line 22, in <module>
    from aiy.cloudspeech import CloudSpeechClient
  File "/home/pi/AIY-projects-python/src/aiy/cloudspeech.py", line 40, in <module>
    END_OF_SINGLE_UTTERANCE = speech.types.StreamingRecognizeResponse.END_OF_SINGLE_UTTERANCE
AttributeError: module 'google.cloud.speech' has no attribute 'types'
pi@raspberrypi:~/AIY-projects-python/src/examples/voice $

Solved it with the following three changes:

from google.cloud import speech_v1 as speech
...
END_OF_SINGLE_UTTERANCE = speech.types.StreamingRecognizeResponse.SpeechEventType.END_OF_SINGLE_UTTERANCE
...
encoding=speech.types.RecognitionConfig.AudioEncoding.LINEAR16,
...

@rabbitmcrabbit what file did you modify? Do you have a diff?

[rabbitmcrabbit]

This was an edit to ~/AIY-projects-python/src/aiy/cloudspeech.py. My apologies, I'm writing from a machine where it's not straightforward to attach a diff, but the start of each line remains unchanged, so you should be able to find the corresponding places.

[bbrendon]

Thanks. I got past this. I would have never figured that out.

It works, thank you.

[nine86]

Thank you! That was super useful.

[AlpenglowInd]

Thank you so much! I was banging my head against that for hours with a fresh install of the 11/20/2020 AIY SD image (hardware is an RPi 3B and I believe a v1 AIY Voice Hat). Worked perfectly.

[LRitzdorf]

Solved for me as well. Is there a PR for this? If not, I'd be happy to make one - this is a rather important issue, since it breaks Cloud Speech functionality.

[petermeester]

I had the same problem with a fresh recent VoiceKit. This solves the problem. Thank you!
