Java Libary / algorithm for filter dictionary words

I am looking for a library or approach to create a java app to filter the non-dictionary words from a long string.

Example:

Quickly capture what’s on your mind and get a reminder later at the right place or time. Speak with Senthil on the go and have it automatically transcribed to My cell# 999-999-9999.

Output - Senthil, cell# 999-999-9999

Let me know if any existing Java lib or algorithm available for this.
