Spain

Description:

The Ahumada_25 database is a subset of the Ahumada database, including the first 25 speakers. The speech files follow these characteristics: the sampling rate is 16.000 Hz for files "M1", "M2", "M3", "M4", "M5" and "M6" (microphone sessions). the sampling rate is 8.000 Hz for files "T1", "T2", "T3" and "M7" (telephone sessions), all files are 16 bits binary, and each file has a 20 byte header, specific of the segmentation software used and independent of the speech samples.
