Speech transcription App

Hello,
I want to build an app that does speech transcription - doesn't have to be real-time. I've seen Amazon's speech API and that looks better than the Google and Microsoft stuff - are there any other options I should be aware of from smaller companies? What's are the advantages and disadvantages of the various options? Thanks in advance

Welcome to the Ranch, Yogesh!

First, a disclaimer. Transcribing speech in Java is difficult, since Java's access to audio hardware is limited by its portability requirements. So I don't really know of any Java speech products, and web-based ones would be an especial problem, since webservers cannot run local audio hardware in any language. I except things like ActiveX controls, since they were just a nightmare anyway.

One of the most popular speech-to-text systems I know of has been IBM's Dragon Naturally Speaking app. I don't know its current status, though and its OS options were limited.

For the Linux and Unix world, one ot the most prominent text-to-speech systems has been Carnegie-Mellon University's Sphinx system, which is available in both full-server and mini-system (Raspberry Pi, for example) flavors.

These are true transcription apps. Of course, if you mainly want simple speech control (a few key words) or "wake-up" apps to front something like Alexa, you have options using things like TensorFlow, which is available on a wide variety of platforms, including some very inexpensive peripheral device boards.
