Is it possible to clean up an audio recording of a lecture using some type of AI system?

Yes, it is possible. Usually, the noise reduction is done using regular signal processing methods, such as spectral subtraction due to demand for low latency. But, of course, modern methods of deep ...

Is it realistic to train a transformer-based model (e.g. GPT) in a self-supervised way directly on the Mel spectrogram?

The reason most music-generation models use discrete representations is because the long-term structures of music are very challenging to model. Note that the MIDI data in MAESTRO (used in the two ...

How can I find a specific word in an audio file?

After some research on the internet, I realized that using VOSK toolkit in python, it can be found (detect) any particular word in audio file or real time audio streaming. https://alphacephei.com/vosk/...

I want to determine how similar a given song is to Queen's songs. Am I headed in the right direction?

You are heading in the right direction to make an audio-based classifier. This is not quite the same as providing a similarity metric between two pieces of audio, but it may do as a first attempt. You ...

What are the differences between RVC and SO-VITS-SVC models?

From what I've seen, these two models have similar architectures since they took the architecture of SoftVC and combine it with the design of VITS. The RVC is a succession of SoVITS and it has some ...

How is speech recognition software able to distinguish between different speakers and yet still understand them all?

I would slightly disagree with Ryan's answer: the fundamental frequency is mainly specific to a speaker. Sounds are defined by other frequency patterns. Vowels, for example, have two bands of energy ...

How is speech recognition software able to distinguish between different speakers and yet still understand them all?

A sound byte can be decomposed into a set of features which are distinguishable by a classifier. The most important feature extracted is the fundamental frequency. This is the lowest frequency ...

Difficulty understanding Keras LSTM fitting data

Yes, intuition says that RNNs like LSTM or GRU will work better in your case, because predicted values might depend on input patterns corresponding to much earlier time intervals. There is no reason ...
