I have a requirement in which I have to extract speech in text from an video file. For instance, say we have an video. I have to capture the audio from it, in text, so that I could store some of the words in DB or similar. I am not sure if this is possible, but just wanted to know the options available.
There are some speech to text Java libraries available, I've not used any so sorry but I can't give any recommendations. I suggest you google for "java speech to text" and see what is available.
