System information

My system is PYNQ Linux, based on Ubuntu 18.04

My Python version is 3.6.5

My Pip version is 9.0.1

My SpeechRecognition library version is 3.8.1

My PyAudio library version is 0.2.11

I am attempting to get speech recognition to run on Xilinx's PYNQ-Z1 and I am getting the following error:

The PYNQ does not have a microphone in port, but it does have a on-board microphone. This is interfaced through the PYNQ's API. A possible problem is that the PYNQ's record output is recorded at a sampling rate of 192000 Hz, which is different than the standard sampling rate. Here is the code I am using that produces this error:

r = sr.Recognizer()
b = "buffer.wav"
pAudio.record(3)
pAudio.save(b)
with sr.AudioFile(b) as src:
    audio = r.record(src)
print(r.recognize_google(audio))

What could possible be causing this HTTPError?

I too am receiving this error, has anyone figured out what is going on? My code was working fine yesterday, and all of a sudden it doesn't work. Any help would be greatly appreciated.

Maybe the length of your audio data might be an issue... https://cloud.google.com/speech-to-text/quotas
