I have found the MIT Mobile Device Speaker Verification Corpus:

https://groups.csail.mit.edu/sls/downloads/mdsvc/index.cgi

And the Gaudi and Ahumada databases, they are 25 speakers each (though the site appears to be down at the moment):

I also made a database with 50 speakers, but I still haven't uploaded it, I need to speak with my advisor first. Contact me in a couple of weeks.

Are there any source where we can get database of dysarthric speech

Hello,

I am looking for a free database for speaker recognition in which each speaker speaks three or four different sentences and repeats each sentence 10 times for example.

Hello Talal and everyone,

If it is for non-commercial research purposes I can offer you the database described in the following article:

http://ieeexplore.ieee.org/document/7743364/

Every speaker uttered six different sentences and there at least 10 repetitions for all but 2 speakers.

Greetings.

Hi All,

I'm currently completing my dissertation on Speaker Recognition.

I've searched fairly extensively for an open source corpus however all posted options appear to be offline.

If you have such a corpus or a recommendation I would much appreciate it.

Hi Nicanor,

I'm working on speaker recognition as part of my MS, so if you could provide the database of speakers, that would be helpful.

Kind regards

Most speaker verification databases like NIST ones are paid. But, there are a couple of freely available databases like Voxceleb (http://www.robots.ox.ac.uk/~vgg/data/voxceleb/) and SITW(http://www.speech.sri.com/projects/sitw/).

Hope that helps!
