Most speech apps measure how you talk. Astound changes how you sound.
Filler-word counters, AI scorecards, roleplay bots, weekly clubs. Astound is the one built on your breath and your voice — with every lesson taught by a real speech therapist.
Each of them does one thing.
We don’t care about filler-words. Or graphs.
Your favourite speakers say “um” too. What they have is breath, presence, and a voice that carries. That’s what we train.
Why our users prefer Astound
4.7 stars from 1,300+ reviews on the App Store.
Breath-focused speaking app
Content wise, the app focuses on breathing. This is an underserved area of public speaking, and if you don’t have proper breath control, it is impossible to be a fully effective speaker.
Major Confidence Boost!
I’ve only had this app for three days but I have already noticed how my voice is projected further and it is also more fluent and free flowing! It has given me a major confidence boost!!
A healthy morning habit
I now start my day by working through some exercises that are helping me to become a more effective communicator whilst taking good care of my precious voice.
Questions
What is the best speech coaching app for iPhone?
It depends on what you need. If you want AI scores on filler words and pace, apps like Orai or Speeko do that. If you want a stronger, steadier voice — breath support, resonance, articulation — Astound is built for it, with lessons from voice coach and speech therapist Leila Bostic. It's rated 4.7 on the App Store and featured by Apple.
How is Astound different from other speech apps?
Most speech apps analyse your recordings and score you. Astound trains the physical voice itself through short, expert-led exercises — and your recordings stay on your phone.
Is Astound free?
Astound is free to download and includes core lessons. Premium unlocks Leila's full library of lessons, courses and packs, billed through your Apple ID and cancellable anytime.
