I'm using W3C Browser Web Speech Api. I search everywhere but i cant find it answer. Is there any limitation for usage ?

The Web Speech API is powerful and somewhat underused. However, there are a few annoying bugs and the SpeechRecognition interface is poorly supported. speechSynthesis works surprisingly well once you iron out all of its quirks and issues.
Google Cloud Speech API is a platform-as-a-service that enables developers to create applications that can process and recognize natural language. The API is free to use for both private and public projects.
Speech recognition can be activated when typing on your Android device. If this facility is available in the app you are using, a microphone icon will appear on the keypad. Pressing this activates the speech recognition. Android does have offline speech recognition capabilities.
Yes, with a bit of a catch. I finally hit a limit recently after a lot of experimentation; as soon as a request starts, it's cut short. On a desktop web browser (Chrome), there's a limit for each user (Primiano Tucci works at Google, so I'd trust him!), and you can't buy more time with the API.
However, as you could see from the first link, the exception appears to be Chrome on Android, which apparently has no limitations because it accesses an internal API for speech recognition when visiting web pages that use the Web Speech API.
For desktop browsers, you're out of luck unless you can assume users don't mind a limit. Even Annyang and voice dictation in Google Docs aren't working for me at the moment, while online voice recognition services that don't go through Google are working.
