Voice Analyst was created by a Speech and Language Therapist who wanted to make her voice therapy sessions more effective and efficient, especially LSVT sessions. It has been recommended as one of the 6 best iOS singing apps for singing teachers (Anne Leatherland, Vocal Process Limited).

Voice Analyst is easy to use and provides immediate visual, acoustic and statistical feedback of voice quality. The frequency response is from 60Hz to 2Khz and volume up to 120dB. Tests have proved Voice Analyst's pitch detection to be accurate to within 5 cents (or 5% of a semitone) across the full spectrum of speech. As a comparison the best human hearing can detect 8 cents.

Speech Tools Limted's lead Speech and Language Therapist is Samantha Brady who qualified as a Speech and Language Therapist in 2001 (PGDip, City University) and gained her Masters in Speech and Language Therapy in 2006 (MSc, City University). She has a wealth of experience of working in a variety of settings and her area of clinical expertise is adult neurology and voice. Samantha is a member of the Royal College of Speech and Language Therapists (RCSLT), HPC Registered (SL10250) and Lee Silverman Voice Treatment Certified (LSVT).

If you are concerned about the quality of your voice, you should see your doctor and request a referral to an Ear, Nose and Throat (ENT) Specialist.

Not very feature rich

I would love to see a few more features, such as analyzing shorter passages selected from a recording or to merge or compare several recordings with the analysis tools.

Also, please allow at least an option for displaying a log scale for the y axis in the pitch graphs.

Developer Response

Hi, Voice Analyst already supports analysing a portion of a recording. If you pinch to zoom then then the statistics apply to the what's visible on the graph.
I'm not sure what you mean by log scale on the y axis as dB is already log scale but please get in touch at to help us understand what you need and we'll do our very best to add it to Voice Analyst.


Amazingly Helpful

Fantastical easy to see where your pitch is, to set target ranges, to make and analyze recordings, and to export and import recordings. I can’t imagine working on my voice without this app.

Developer Response

Thanks for letting us know. If you'd like to see anything added then send us a mail to and we'll add it to our roadmap.


Excellent but...

What a wonderful and handy tool. As far as I can tell the foundation technology is excellent. There are times when the UI is a bit limited and frustrating. I’d like to see that improved. In the meantime I love it nonetheless.

Developer Response

Hi, we're just putting the finishing touches to our latest update which simplifies the interface and adds some new features like targets and cloud import/export. Could you send an email to and let us know what we can do to earn that last star?
