@goxr3plus Is it the new Speech API on Google can use for commercial? |
|
Yes you can use the Official Google Library Commercialy :) Check their repo. |
|
By the way i have played with The Speech API google official library .. i find it pretty tricky for junior developers . You need to be good in Java to understand it .... unlike this repository here which makes it very simple. |
|
Thanks @goxr3plus . So Your project only base on based on Chromium Speech API key haven't to add support for the Official Google Cloud Speech API now ? |
|
By the way, Is it free use the official Google Library for commercial? I want to use speech to text api free. Thanks. |
|
Yes the official one can be used Commercially. My examples on the read me
are for this repository. The code you see above is for the official Google
Speech API.

What exactly can I use for commercial use? I didn't understand that really. Can I use your code for commercial or do I have to look for another Google speech library? I'm a little bit confused now, sorry, so what exactly cn I use for commercial. |
|
Well Google used to have two apis. Private Speech Api and the other one for commercial use. This library supports the private speech api, you should go to the official Google Speech Api Library and that above example is written for it :) |
|
Sorry sometimes I'm a little bit slow with understanding. My English isn't so good. So when I understood this right I can't use the java-google-speech-api for commercial use, can I? But the library under this link https://github.com/googleapis/java-speech is for commercial use, right? And for what exactly is your script, you wrote above? |
|
So when I wrote this library there was not any official library for Java :). Now that it exists I would definitely go with that. THE script above is a script for using that library you added on link. If the script still works because it's been time :) |
|
Ok but the library I get to with the link is for commercial use right? Sorry if I'm annoying but thank you for your answers! |
|
A further question: I don't see where your code is giving me an answer from the server. Could you tell me the line where this happens? And could you please answer the question in the comment above this comment? Thak you very much! |
|
@Jochen-sys No you are not annoying don't worry. It's been 3 years since i lastly played with Google Speech Recognition many things have changed , please follow the official documentation for new examples and ask questions on their repository about that . That's how i did it back then :) https://github.com/googleapis/java-speech Open issues to them asking what is not working for you etc . For any further help if i know i would gladly be here . I am a React and React Native developer now :) |
This project is based on Chromium Speech API key.That API has a lot stricter limits than the new Speech API on Google Cloud (which is also free).
We have to add support for the Official Google Cloud Speech API . I don't know if this would be hard or not but i know it should be done .
Google is releasing it's own library for that , though it is very very alpha check here
