Is there something like OpenCV for voice recognition and NLP? As you know, OpenCV is a great open-source library for image recognition and related tasks.
Is there a similar library for voice recognition and natural language processing (NPP)?
I know espeak for TTS, also pocketsphinx for voice recognition. Are there better options?
I don't know about voice recognition, but, for NLP, I think that Gensim could be what you are looking for.
Gensim is an NLP package that contains efficient implementations of many well-known functionalities for the tasks of topic modeling, such as tf–idf, Latent Dirichlet allocation, Latent semantic analysis, etc.
