Voice Recording Using Pyaudio
Solution 1:
First, make sure your microphone is actually connected, on and not muted.
You are not providing a device index when opening the stream. This means that you will get the device that PyAudio considers the default. Which might not be your microphone.
Use the get_device_count
and get_device_info_by_index
methods of the PyAudio
object in an interactive Python session. Print the dictionaries that get_device_info_by_index
returns to determine which device index represents your microphone, and provide that index number as the input_device_index
parameter when opening the stream.
Solution 2:
below code will list indexes of the available recording devices,then user can give a specific index as the input,code will start recording via given recording device index.
import pyaudio
import wave
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
CHUNK = 512
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "recordedFile.wav"
device_index = 2
audio = pyaudio.PyAudio()
print("----------------------record device list---------------------")
info = audio.get_host_api_info_by_index(0)
numdevices = info.get('deviceCount')
for i inrange(0, numdevices):
if (audio.get_device_info_by_host_api_device_index(0, i).get('maxInputChannels')) > 0:
print("Input Device id ", i, " - ", audio.get_device_info_by_host_api_device_index(0, i).get('name'))
print("-------------------------------------------------------------")
index = int(input())
print("recording via index "+str(index))
stream = audio.open(format=FORMAT, channels=CHANNELS,
rate=RATE, input=True,input_device_index = index,
frames_per_buffer=CHUNK)
print ("recording started")
Recordframes = []
for i inrange(0, int(RATE / CHUNK * RECORD_SECONDS)):
data = stream.read(CHUNK)
Recordframes.append(data)
print ("recording stopped")
stream.stop_stream()
stream.close()
audio.terminate()
waveFile = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
waveFile.setnchannels(CHANNELS)
waveFile.setsampwidth(audio.get_sample_size(FORMAT))
waveFile.setframerate(RATE)
waveFile.writeframes(b''.join(Recordframes))
waveFile.close()
Solution 3:
Your code works in my environment: Win7 and Python3.4 - I get my voice recorded using my Laptops's microphone. Maybe your microphone's recording level is set too low. Or is it muted or disabled?
Solution 4:
Make sure your Microphone is connected to the computer. It can be identified using below code.
import speech_recognition as sr
for index, name inenumerate(sr.Microphone.list_microphone_names()):
print("Microphone with name \"{1}\" found for microphone(device_index{0})".format(index, name))
