Background audio files about diy-alexa HOT 30 CLOSED

Whya are you didn't response for my question 😔??

I have other things to do as well as support GitHub projects!

Some of your questions can be answered by reading and understanding the code in the notebook.

You download the speech commands dataset and uncompress it to the speech_data folder. Follow the instructions at the top of the notebook:

Download data set
Download from: https://storage.cloud.google.com/download.tensorflow.org/data/speech_commands_v0.02.tar.gz - approx 2.3 GB

And then run

tar -xzf data_speech_commands_v0.02.tar.gz -C speech_data

This will give you a folder containing a list of words along with sample audio for each word.

The code runs over the list of words and extracts features for each word. If the word is the wake word - in our case "marvin" then we repeat it multiple times so that we have a balanced data set - approximately an equal number of wake words examples vs non-wakeword examples.

I've added an additional folder to the speech_data folder with some background noise audio. Just create a folder in the speech_data folder called _background_noise_ and put some recordings there of background noise.

If you don't have any background noise then comment out these lines:

for file_name in tqdm(get_files('_background_noise_'), desc="Processing Background Noise"):
    process_background(file_name, words.index("_background"))

The same is true for _problem_noise_. Create a folder called _problem_noise_ in the speech data folder and put audio that seems to confuse the neural network there.

Once again if you don't have any problem noise samples then comment out these lines:

for file_name in tqdm(get_files("_problem_noise_"), desc="Processing problem noise"):
    process_problem_noise(file_name, words.index("_background"))

The same is the case for the _mar_sounds_. I recorded a bunch of words that sound like "marvin" to help the neural network ignore similar words.

Comment out these lines if you don't have these samples:

for file_name in tqdm(get_files("_mar_sounds_"), desc="Processing problem noise"):
    process_mar_sounds(file_name, words.index("_background"))

I put the speech_data file to the model folder now it's working pretty thanks you solve my issue thank you

ok i want to know are you use background audio files for training data??

from diy-alexa.

You want to train the neural network to detect your wake word. To do this it needs example audio files containing your wake word and example audio files that don't contain your wake word. These counter examples can be other words and background noise.

You also want it to be able to detect your wake word even when there is background noise. Or at least to be reasonably robust when there is background noise.

The background noise is used in the training of the neural network.

ok how i training the neural network ?? using a jupyter notebook??

from diy-alexa.

You can use the jupyter notebooks in the repository, but if you want to use different training data then you will need to modify the code.

There are some good tutorials on the TensorFlow website that you can use to learn how it all works, but you are in for a lot work!

now I run the training data notebook but it'll occur an error "Processing problem noise" what is the reason??

from diy-alexa.

how do you add the audio sample to the training data??

from diy-alexa.

I recorded audio using my computer and built-in microphone to record additional background sounds.

You can comment out the lines that deal with the "mar" sounds if you don't need it.

I ask how you add audio sample to the Jupyter notebook

from diy-alexa.

I'm afraid the question doesn't make sense to me.

Are you asking how to read audio data into Python?

I think that you should follow some tutorials using jupyter notebook and tensorflow to learn more. The link I sent previously: https://www.tensorflow.org/overview is a good place to start.

There is also a good set of videos here: that will be very helpful for you to watch: https://www.youtube.com/playlist?list=PL-wATfeyAMNrtbkCNsLcpoAyBBRJZVlnf

Ok i will watch the tutorial but i want to know are you add audio samples to the Jupyter notebook

from diy-alexa.

If you can't understand my question, let me know and I will try to explain my question a bit detail

from diy-alexa.

I don't understand your question.

from diy-alexa.

Are we need to add this data_speech_commands folder to the notebook then it will run through all these samples and output files?

from diy-alexa.

I think you need to add command data file to the jupyter notebook ,friend . I also have this question .I also wait his reply

Ok i know 🙂 i was thinked you still can't understand my question

process_background(file_name

That's mean when i haven't background audio files then can i use this function
" for file_name in tqdm(get_files('background_noise'), desc="Processing Background Noise"):
process_background(file_name, words.index("_background")) " ??

And then run

tar -xzf data_speech_commands_v0.02.tar.gz -C speech_data

Where i run this ?? on command prompt ??

You run this on the command prompt in the model folder. I don't think this will work in the normal windows command prompt. You would be better off installing WSL so that you have the full set of UNIX commands to work with.

Create a folder called background_noise in the speech_data folder and put the files there.

Yes it's not work correctly in Windows command prompt,we can also use Ubuntu software on windows for this work

I run this "Generate Training Data " notebook but it occurs an error "Processing Background Noise:0/0 [00:00<?it/s]0 0 0" what is the reason??

in your video, there is no occur that error

watch the difference between these screenshots what is the reason

from diy-alexa.

Why do you think it is happening? I don't know what is happening on your machine you need to debug the code and work out what the problem is.

It seems likely that it can't find the audio files. Have you downloaded the speech data and extracted it? Is it in the right place? Where is the code looking for the files?

What is the directory structure? You should have something like:

model/speech_data/

I also think it's can't find the audio files.yes i downloaded the speech data and extract in right click on zip file and extract it.i not place anywhere that file. I just only download and extract it

from diy-alexa.

You need to create a folder called speech_data in the model folder (where you are running the notebooks) and copy the extracted files into that folder.

It expects to have all the words from the commands dataset under the speech_data folder.

How I copied the speech data folder to model folder?? Are you meaned notebook saved location to copy the speech data folder??
