I have involved and interested to estimate the age of users through speech signals. Kindly suggest some of the free corpus available to do this research.
I don't know of any corpora pertaining to this question specifically. However, Carnegie Mellon has lots of free corpora available for research purposes. Perhaps you can repurpose one to fit your needs.
Thanks for your kind response, Silber. I have searched for the corpus links but i couldn't find the link. Can you share the url link related with free corpus maintained by carnegie mellon university that will be helpful.
