VoiceChanger might not yet be the perfect tweak to change your voice in real-time but it breaks the ice in active, real-time voice-changing. It's one of the new tweaks to hit Cydia that has something really unique to offer.
As such, I don't think there are apps or tweaks on App Store or Cydia, respectively, that bring this feature to the table. The best we've seen so far is call-recording facility (specifically for 4S/5) and you might be interested in noting that this new tweak, VoiceChanger, is from the same developer.
Elias Limneos first came across our radar when he released CallRecorder/AudioRecorder – a tweak to record calls on your iPhone. Incidentally, the tweak was compatible to work only with the latest iPhones.
VoiceChanger lets you change your voice: whether it's being recorded by the Voice Memo or whether it's on a call or on a video recording utility.
Once installed, VoiceChanger can be enabled/disabled via Settings. Besides the kill switch, there are options to change the type of voice. You have four options:
- Dark Lord
There's also the no-effect for Normal voice.
There's one major hurdle/problem for the tweak, though. The voice quality is actually quite pathetic. You will pass-off with Tenoro and Dark Lord but the Smurf or Rumpelstiltskin isn't up to the mark.
May be things will get refined with updates but for now, you have to put up with these if you wish to use VoiceChanger.
VoiceChanger can be enabled and used even during a call. However, you'll have to enter into Settings and enable it thereby exiting the Phone app. Not a big deal but if there had been Activator actions, things would have sounded far better.
VoiceChanger is available on the BigBoss repo for $2.99. A pricey-tweak, yes, but a tweak to check out nevertheless. That is, if you're into pranks.
