This means that your bot is missing permissions to (presumably) send messages on that server. You can prevent it from crashing by adding a .catch statement after sending the message like this:

With the newest update to Discords API your final line should be changed to this:

It's deprecated because they now expect you to use Java 8 and implement the interface DefaultLifecycleObserver. Since Java 8 allows interfaces to have default implementations, they defined DefaultLifecycleObserver with empty implementations of all the methods so you only need to override the ones you use.

The old way of marking functions with @OnLifecycleEvent was a crutch for pre-Java 8 projects. This was the only way to allow a class to selectively choose which lifecycle events it cared about. The alternative would have been to force those classes to override all the lifecycle interface methods, even if leaving them empty.

In your case, change your class to implement DefaultLifecycleObserver and change your functions to override the applicable functions of DefaultLifecycleObserver. If your project isn't using Java 8 yet, you need to update your Gradle build files. Put these in the android block in your module's build.gradle:

Check e.g. this part of the MelGAN code: https://github.com/descriptinc/melgan-neurips/blob/master/mel2wav/modules.py#L26

Specifically, the Audio2Mel module simply uses standard methods to create log-magnitude mel spectrograms like this:

• Compute the STFT by applying the Fourier transform to windows of the input audio,
• Take the magnitude of the resulting complex spectrogram,
• Multiply the magnitude spectrogram by a mel filter matrix. Note that they actually get this matrix from librosa!
• Take the logarithm of the resulting mel spectrogram.

Your confusion might stem from the fact that, usually, authors of Deep Learning papers only mean their mel-to-audio "decoder" when they talk about "vocoders" -- the audio-to-mel part is always more or less the same. I say this might be confusing since, to my understanding, the classical meaning of the term "vocoder" includes both an encoder and a decoder.

Unfortunately, these methods will not always work exactly in the same manner as there are e.g. different methods to create the mel filter matrix, different padding conventions etc.

For example, librosa.stft has a center argument that will pad the audio before applying the STFT, while tensorflow.signal.stft does not have this (it would require manual padding beforehand).

An example for the different methods to create mel filters would be the htk argument in librosa.filters.mel, which switches between the "HTK" method and "Slaney". Again taking Tensorflow as an example, tf.signal.linear_to_mel_weight_matrix does not support this argument and always uses the HTK method. Unfortunately, I am not familiar with torchaudio, so I don't know if you need to be careful there, as well.

Finally, there are of course many parameters such as the STFT window size, hop length, the frequencies covered by the mel filters etc, and changing these relative to what a reference implementation used may impact your results. Since different code repositories likely use slightly different parameters, I suppose the answer to your question "will every method do the operation(to create a mel spectrogram) in the same manner?" is "not really". At the end of the day, you will have to settle for one set of parameters either way...

The direction Mel -> Audio is hard. Not even Mel -> ("normal") spectrogram is well-defined since the conversion to mel spectrum is lossy and cannot be inverted. Finally, converting a spectrogram to audio is difficult since the phase needs to be estimated. You may be familiar with methods like Griffin-Lim (again, librosa has it so you can try it out). These produce noisy, low-quality audio. So the research focuses on improving this process using powerful models.

On the other hand, Audio -> Mel is simple, well-defined and fast. There is no need to define "custom encoders".

Now, a whole different question is whether mel spectrograms are a "good" encoding. Using methods like variational autoencoders, you could perhaps find better (e.g. more compact, less lossy) audio encodings. These would include custom encoders and decoders and you would not get away with standard librosa functions...

OK, I found out what was wrong. I was using Microsoft Edge and it seems that Edge only shows some of Microsoft voices. If I use Firefox, the other installed voices will also show up. So it was Edge's fault.

This is just my guess, but maybe variable response is not detected as a string. What you may want to try:

I installed pyttsx3 using the two commands in the terminal on the Raspberry Pi:

1. sudo apt update && sudo apt install espeak ffmpeg libespeak1
2. pip install pyttsx3

I followed the video youtube.com/watch?v=AWhDDl-7Iis&ab_channel=AiPhile to install pyttsx3. My functional code should also be listed above. My question should be resolved but hopefully useful to anyone looking to write a similar program. I have made minor tweaks to my code.

Ok, I was able to work around the problem myself. It was in fact the runAndWait() function from pyttsx3 that was breaking the program. Instead, I now use a combination of gTTS, pydub, soundfile, playsound, and pyrubberband.

The speak function now looks like this:

Your activity is getting stopped or destroyed and that's why your timer gets stuck. To keep the timer running even if the app is closed or killed, see this way:-

You can use this technique to detect how long the user was inactive (even when the app is in the background).

1. Create a SharedPreference & its Editor object. Then declare 3 long variables such:
