Create a recording

# import required libraries
import sounddevice as sd
from scipy.io.wavfile import write
import wavio as wv
# Sampling frequency
freq = 44100
# Recording duration
duration = 20
# Start recorder with the given values 
# of duration and sample frequency
recording = sd.rec(int(duration * freq), 
                   samplerate=freq, channels=2)
# Record audio for the given number of seconds
# This will convert the NumPy array to an audio
# file with the given sampling frequency
# write("recording0.wav", freq, recording)
# Convert the NumPy array to audio file
wv.write(fileo, recording, freq, sampwidth=2)

To make it an arbitrary duration


Convert Audio to text

import speech_recognition as sr

AUDIO_FILE = fileo
r = sr.Recognizer()
with sr.AudioFile(AUDIO_FILE) as source:
    audio = r.record(source)  # read the entire audio file

    # we're just using the default API key
    print("->> " + 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))
