How can i make endpoint detection

melisaztrk

I want to use endpoint detection to remove unwanted noises from a voice record. How can i use it ? How can i calculate short-term energy and short-term zero crossing rate ? What should i do after calculation ?

It sounds like you have a lot of specific voice and speech requirements for whatever your project is.

The general theory and methods might be covered in a good Intro to Speech Processing book.

You might also find examples with the search "Java endpoint detection" -- e.g.:

Good luck with your project -- were either of those code example of endpoint detection helpful?

Thanks, this project is difficult to do alone so i changed my project subject. But if i continue , i think those code would help.

Good luck with your new project, @melisaztrk -- let the forum know if there is anything we can answer.
