| These wav files show how Sonic performs at increasing speech rates. |
| |
| 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. |
| |
| voxin_s110.wav |
| This was generated with 'say -s110 -f test1.txt -w voxin_s110.wav'. It's about |
| 3.1X faster than voxin's default rate. |
| |
| voxin_sonic_3.1x.wav |
| This was generated with 'say -f test1.txt -w out.wav; sonic 3.1 out.wav |
| voxin_sonic_3.1x.wav'. It sounds almost identical to voxin_s110.wav, as far as I can |
| tell, though one blind listener says he prefers the sound of voxin when sped up |
| using sonic. |
| |
| voxin_s130.wav |
| This was generated with 'say -s130 -f test1.txt -w voxin_s130.wav'. It's about |
| 4.4X faster than voxin's default rate. |
| |
| voxin_sonic_4.4x.wav |
| This was generated with 'say -f test1.txt -w out.wav; sonic 4.4 out.wav |
| voxin_sonic_4.4x.wav'. It sounds almost identical to voxin_s110.wav, as far as I can |
| tell, though one blind listener says he prefers the sound of voxin when sped up |
| using sonic. |
