Python is de facto the most common used programming language in natural language processing (NLP) vertical, also because the huge ecosystem of open-source packages (libraries), e.g. to develop machine learning / deep learning alghorithms (Tensorflow, Pytorch, etc.), speech recognition (Vosk, Coqui, etc.), sound processing, etc.
