README
These wav files show how Sonic performs at increasing speech rates. All sound sampels are in the public domain. sonic.wav This is a sonic 2X sped-up version of a public domain librivox.org recording, from the audiobook "Princess of Mars". soundtouch.wav This is the same recording as sonic.wav, but sped up using soundtouch, which uses WSOLA rather than the sonic algorithm. Even at 2X speed up, you should be able to hear the characteristic WSOLA distortion relative to the sonic version. talking.wav This is my father talking, using a decent microphone and 44KHz sample rate. talking_2x.wav This is his voice sped up by 2X using Sonic. espeak_s450.wav Sonic also performs well at increasing the speed of synthesized speech. espeak_s450.wav was generated using 'espeak -s450 -f test1.txt -w espeak_s450.wav'. This is the highest speed currently supported by espeak, though Sonic can speed up espeak to much faster rates. espeak_sonic.wav This was generated with 'espeak -f test1.txt -w out.wav; sonic 2.6 out.wav espeak_sonic.wav'. Sonic sped it up 2.6X, which is about the same speed as espeak at -s450. I personally feel that the sonic sped up sample sounds better than espeak at -s450. twosineperiods.wav This is just two sine periods, which is too short to hear. However, it's useful for making sure the flush function works correctly. A 2-X speedup should result in one sine period with no distortion.
