Numpy-based NIST SPH audio-file reader
Numpy-based NIST SPH audio-file reader. This is for use with NIST SPH audio-files, the most likely use being extracting the TEDLIUM_release2 audio into formats that standard tools can easily process.
Note that this library doesn’t require any external tools such as vox or gstreamer. It just loads the data into a numpy array and then lets you dump it back out to wave files.
from sphfile import SPHFile sph =SPHFile( 'TEDLIUM_release2/test/sph/JamesCameron_2010.sph' ) # Note that the following loads the whole file into ram print( sph.format ) # write out a wav file with content from 111.29 to 123.57 seconds sph.write_wav( 'test.wav', 111.29, 123.57 )
