kandi X-RAY | VAD Summary
Voice activity detection (VAD), also known as speech activity detection or speech detection, is a technique used in speech processing in which the presence or absence of human speech is detected. The main uses of VAD are in speech coding and speech recognition. It can facilitate speech processing, and can also be used to deactivate some processes during non-speech section of an audio session: it can avoid unnecessary coding/transmission of silence packets in Voice over Internet Protocol applications, saving on computation and on network bandwidth. Voice activity detection (VAD) was first investigated for use on time-assignment speech interpolation (TASI) systems. VAD is an important step in speech processing applications such as mobile telephony, speech enhancement as well as speech and speaker recognition, and it is particularly important in the field of speech recognition. Typical models for VAD include support vector machine (SVM), Gaussian mixture model (GMM), recurrent neural network (RNN) and deep neural network (DNN).

QUESTION
I'm doing NLP with the tidymodels framework, taking advantage of the textrecipes package, which has recipe steps for text preprocessing. Here, step_tokenize
takes a character vector as input and returns a tokenlist
object. Now, I want to perform spell checking on the new tokenized variable with a custom function for correct spelling, using functions from the hunspell package, but I get the following error (link to the spell check blog post):
ANSWER
Answered 2021-Nov-18 at 17:58There isn't a canonical way to do this using {textrecipes} yet. We need 2 things, a function that takes a vector of tokens and returns spell-checked tokens (you provided that) and a way to apply that function to each element of the tokenlist
. For now, there isn't a general step that lets you do that, but you can cheat it by passing the function to custom_stemmer
in step_stem()
. Giving you the results you want

QUESTION
In an online game, students are asked "How many 12-year-olds already have (…)" and have to choose how many of 25 people's icons (4%) they color in. This is actually kind of a range input, but I thought it could be done easily with an input type="number" too.
I've already got it working to some extent. Arrow up or mouse up adds the necessary class, but the remove class doesn't work yet. When I enter a number, the people's icon with that number gets the class, but all icons with a lower id should also get the class.
You can find the live example here. The code I'm using:

QUESTION
I am trying to run the example code of webRTC VAD
found here.
But when I feed it a mono-16bit wave file of just me speaking with very long pauses, it just detects the entire file to be voiced, and the voiced output chunk-00.wav
is the entire audio file.
Any help is greatly appreciated. Below I have given the console output that I receive.
...ANSWER
Answered 2022-Jan-31 at 11:45I think I have found an alternative method of how to get VAD data. Instead of trying to get VAD from the pre-defined method shown in the link above, I create my own function.
The function basically measures the amplitude of the wave and any sharp spike observed above the base noise level (1.6x the base value
) is taken to mean a voiced activity. This function assumes that only 1 human is speaking and that the noise level remains relatively constant.
QUESTION
I am trying to make a speech to text system using raspberry pi. There are many problems with VAD. I am using DeepCpeech's VAD script. Adafruit I2S MEMS microphone accepts only 32-bit PCM audio. So I modified the script to record 32-bit audio and then convert it to 16 bit for DeepSpeech's processing. Frames generation and conversation parts are below:
...ANSWER
Answered 2022-Jan-26 at 13:36I searched for DeepCpeech's VAD script and found it. The problem is connected with the webrtcvad. The webrtcvad VAD only accepts 16-bit mono PCM audio, sampled at 8000, 16000, 32000 or 48000 Hz. So you need to convert the 32-bit frame to 16-bit (I am about PyAudio output frame) to process webrtcvad.is_speech(). I changed and it worked fine.

QUESTION
I am developing an algorithm for real-time speaker identification. My idea was to run three tasks, namely writeAudio()
, detectionBlock()
, and identificationBlock()
, in parallel using the multiprocessing
module.
In effect, the writeAudio()
function uses PyAudio
to capture a continuous recording and save the 0.5-second audio files to a local directory, the detectionBlock()
function processes the two oldest 0.5-second files from the directory and uses a Voice Activity Detection (VAD) model to determine if the audio is speech or noise, and the identificationBlock()
function processes a separate 3-second audio file (saved to a different directory from a chunk of 0.5-second audio files) and then uses a Voice Recognition (VR) model to determine the speaker's identity.
I was hoping that I could apply multiprocessing
here to sidestep the Global Interpreter Lock (GIL) and run the three functions simultaneously as Process
objects. Currently, the program won't start running the detectionBlock()
or identificationBlock()
functions until after writeAudio()
has finished recording.
Here's the code for the current implementation with multiprocessing
:
ANSWER
Answered 2021-Jun-25 at 16:54Here's an example of what I mentioned in the comments. I don't have all the components to actually run it, so treat it a bit like pseudocode, but I believe it should be a good jumping off point. The main improvement is a bit of simplification courtesy of pastream
which claims basically GIL-less portaudio
iteration. The benefit here is less overhead and easier transfer of data to at least the first stage in the pipeline which is detecting audio. You may need some additional complexity to drop frames in the event of a slowdown, but this structure should generally work provided I understood the pastream
docs correctly.

...ANSWER
Answered 2021-Jun-01 at 20:57Because all of your returns
are in the while loop.
From msdn: msdn
- The while statement: conditionally executes its body zero or more times.
Meaning that is not guaranteed that the code inside the while
loop will be executed at all. It might just skip the whole, but no returns
after it, that's why you are getting an error: "Not all code paths return a value"
, although multiple paths returns
a value, NOT all path.
You specified that the mattaVag
variable is true
at the beginning but the compiler doesn't know it. If this loop will be executed at least one time anyway, change it to do...while
.
Or place the return b;
outside your loop
