I'm looking for a database for development of speaker verification system. Specifically, it should contain recordings of 200+ speakers without any background noise and ideally without or with minimal reverb. The minimal sampling rate is 44.1kHz, so it contain full-band audio signal. Does anyone know if LDC sources or any free corpora fullfill theese requirements?
If this helps in any way:
IITG Multuvaribility Phase-I Speaker Recognition database contains two sessions speech data from 100 speakers collected in an office environment using Digital Voice Recorder which have 44.1k sampling rate. But it is paid database.

IITG MV Phase-II database has 104 speakers but the environment is not clean.
