I am planning to build speech to text program for my community. It would be a new language which doesn't exist in google yet.
Probably, it's like this IBM's tool. ( For instance, if I speak my language, speech to text program will text my language words. )
I know Javascript and PHP.
And I am still learning python.
1 - Can I build it with just a web knowledge such as Javascript and PHP?
2 - If you think it would be very difficult for me to develop that kind of tool. Which service or program should I use? or buy it?
