Could not find PyAudio

[HAKANMAZI]

I installed chaquopy on my Android Studio then ı tried to run below code

import speech_recognition as sr
import time

r = sr.Recognizer()
mic = sr.Microphone()

def transcript(transcript=''):
    with mic as source:
        r.adjust_for_ambient_noise(source)
        audio = r.listen(source)
    try:
        transcript = r.recognize_google(audio,language='tr-TR')
    except sr.UnknownValueError:
        time.sleep(1)
    except sr.RequestError:
        time.sleep(1)

    return transcript

But I got this error

Thanks for the report. Unfortunately Android doesn't support any of the standard Linux audio APIs, so I think PyAudio / PortAudio would require a new backend in order to work.

If anyone else needs this package, please click the thumbs-up button above and subscribe to this issue, and we may look into it in the future.

Is there any progress on this subject?

[mhsmith]

Not yet, sorry.

After three days of searching a solution i came to know that it is not compatible with android studio 🥲 i am a beginner/student i wanted to implement PayAudio in my Final year project.. my request is to please make it possible... I there any alternative i can use with my android app ?

[mhsmith]

You can use the standard Android audio APIs directly, either in Java, Kotlin, or in Python using the Chaquopy API. For an example, see here.

i think our goal is to convert speech to text real time. so i have an idea, we pass bytes array as agrument of python function, then python function detect and return text to android . Is this solution possible?

[mhsmith]

Yes, that should be possible. But I don't think we currently support any Python packages which can decode compressed audio, unless there's a pure-Python option I don't know abot. So you'd have to pass the audio as an uncompressed WAV file, or raw PCM.

After 3 years any progress?

No, because as I said above, this would require a substantial amount of work on PyAudio's side.
