Hello,
i have installed the module and want to run this code:
#!/usr/bin/python
# -*- coding: utf-8 -*-
from vad import VAD
detector = VAD()
However, i get this error:
detector = VAD()
TypeError: init() takes at least 2 arguments (1 given)
Any suggestions? Thanks!
I want to integrate this VAD into the SpeechRecognition Module.
So i have this buffer variable and ant to convert it to a ndarray in order to use it as an input for the VAD:
from vad import VAD
import numpy as np
FS_RATE = 16000
detector = VAD(fs=FS_RATE)
....
buffer = source.stream.read(source.CHUNK)
...
signal = np.fromstring(buffer, dtype=np.int16)
signal = signal.astype(np.float32)
speech = detector.detect_speech(signal, FS_RATE)
....
However, i get an error when using the detect_speech()
function:
('Unexpected error:', <type 'exceptions.TypeError'>)
Any suggestions?
Thanks!
What is the expected "shape" of the signal?
Let's say I'm providing a signal that is one second long at 44100 sampling frequency. Does vad expect a one-dimensional numpy array of 44100 entries? Also, what does it return? Should it return an array of 44100 booleans? Also, what's a typical value for threshold?
I'm using python sounddevice InputStream to receive audio.

cols = int(np.ceil((s.shape[0] - self.wlen) / self.fshift + 1))
