I was trying to build a speech-to-text recognition with python on macOS (please do not post suggestions for Windows devices here).
I'm trying to use the SpeechRecognition example code and developing my application, but every time I try to run the code I get the following error:
OSError: [Errno -9986] Internal PortAudio error
I already have installed PortAudio with
brew install portaudio and PyAudio as well with
pip3 install pyaudio.
Here is the example code:
import speech_recognition as sr
# obtain audio from the microphone
r = sr.Recognizer()
with sr.Microphone() as source:
print("Say something!")
audio = r.listen(source)
# recognize speech using Google Speech Recognition
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))
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))
This is the traceback of the error message:
||PaMacCore (AUHAL)|| Error on line 1277: err='-66748', msg=Unknown Error
