Been using Vocular How deep is your voice for a couple months now. It’s basically an app that analyzes your voice and compares it to data from over 150 celebrities to help you understand your voice and learn how to improve it. Pretty solid app if you’re into that kind of thing.
Here’s what you do: the app gives you a full analysis of your voice in terms of depth and variety. It calculates a set of celebrity matches to give you a grounding of what your results mean. There’s also an on-the-fly pitch tracker – so you can practice different ways of speaking and immediately see their effect. And it’s got unlimited archive space and a charting tool so you can track your progress over time.
Look, if you’re into voice training and that kinda stuff, you’ll probably like this. It’s not perfect – the upgrades can take forever at higher levels – but overall it does the job. Worth checking out.
