Cantaris is a desktop app for Mac and Windows that records, measures and tracks the voice, built for voice professionals and voice scientists. What you hear in a session or a lesson becomes data you can compare, document and share.
Cantaris runs on Windows and macOS. Try it with your own equipment, your own clients, your own voices.
You hear breathiness, strain, instability, a range that won't open. Cantaris turns those impressions into numbers and pictures — CPPS, HNR, jitter, pitch and loudness, Vocal Ring, the tessitura against the piece being sung. In a session or a lesson they become a shared language between you and the voice in front of you.
Scientific-level calibration with Praat under the hood. All acoustic data is saved automatically, with CSV and WAV batch export for anything downstream. Full per-user encryption, with optional shared workspaces on network drives.

A complete voice field in twelve simple recordings, with live feedback that shows the singer, client or student exactly what their voice is doing the moment they're doing it.
Cantaris plots every voiced frame on an interactive piano diagram: pitch along the keyboard, loudness up the y-axis in calibrated dB.
Where the phonetogram uses sustained vowels and glides, the Speech Range Profile captures pitch and loudness in connected speech — the way the voice actually works while talking.
Four short conditions — soft, normal, loud and an optional shout — each return an average pitch, its musical note, and a loudness in calibrated dB. Typically the speech profile sits well inside the full range; when it crowds the edges, you can see it.
The Song Range Profile records and analyses a sung performance, so the singing voice can be assessed separately from speech — built for singers, teachers and vocal coaching.
The passage is plotted on the same pitch-and-loudness diagram, ready to overlay and compare. Across a training period the takes line up side by side, so an opening range is something you can point to.
The Phonanium Voice Lab is the voice-science package of Cantaris. It adds aerodynamic, acoustic and perceptual measures from the research literature — maximum phonation time, Dysphonia Severity Index (DSI), Acoustic Voice Quality Index (AVQI), and your own perceptual rating — so they all live in one shared record.
Phonanium Voice Lab offers extra options for the moments you need to look closer — research-grade analyses with the editing tools to get to the right second of audio.
A waveform you can zoom, pan and scroll. Click-and-drag to select a region and run deeper Praat-based analyses on selections.
Finally, a voice analysis tool that doesn't require a tech degree. Cantaris is clear, quick and fits right into my sessions without disrupting the flow.
The measurements are reliable and the reports make communication with my clients so much easier. I spend less time explaining and more time coaching.
The built-in tutorials and the clarity of the interface are a game changer. I felt confident using Cantaris from day one — no onboarding headaches whatsoever.
Licensed per two computers. Every plan includes every mode plus all updates within the licensed period.
We work with institutional purchasing. Everything your finance and IT departments are likely to ask for is set out below, so you can get started without a call.
Email us at institutions@cantaris-software.com with your institution, the number of users or workstations, and the license period you have in mind. We reply by return with a formal quotation as a PDF, valid for thirty days and carrying our full company, VAT and bank details — a document you can hand straight to purchasing.
Quotations for institutions in the United States are issued in dollars, and the USD amount on the quotation is the amount you are charged. The figure your department approves is the figure on the invoice, with no exchange-rate difference appearing in between.
We accept purchase orders and invoice against your PO number on thirty-day terms. Payment can be made by bank transfer, or by departmental purchasing card where your institution allows it.
Cantaris runs entirely on the local machine. Recordings, case files and results are written to the device and stay there — there is no cloud and no server behind the software, nothing is transmitted to us, and we hold no customer recordings of any kind. For most IT reviews, that answers the question before it is asked.
Data is encrypted per user at rest, and teams that want to work from a shared library can point Cantaris at a workspace on your own network drive, under your own access control.
Cantaris does not diagnose. It records the voice and reports objective measures of the sound signal; the interpretation stays entirely with the professional. More on data protection →
The paperwork your legal and purchasing departments will want to read before a requisition is raised. Any further vendor or tax documentation your finance department needs, we will provide on request.
* One license covers two computers. Every plan includes every mode — the voice, speech and song range profiles, the Phonanium Voice Lab, and the further detailed analyses — plus all updates within your licensed period.

"I created Cantaris with one clear purpose: to objectify and measure my work as a voice specialist, and visualize for my clients what we hear and feel. From the moment I started using it, I noticed some real benefits. Explaining how a client's voice works became much easier."
Youri Maryn (PhD) is a clinical speech-language pathologist (European Institute for ORL-HNS-SBS) and visiting professor in voice disorders and instrumental phonetics (Ghent University, University College Ghent). In his research he focuses on various topics related to voice pathology, clinical voice assessment, and clinical voice treatment. Supported by all his research on and developments in the clinical assessment of acoustic voice/speech signals, he founded the company Phonanium in 2017 under the motto of “State-of-the-art voice/speech documentation through sophisticated and high-quality yet accessible acoustic voice/speech analyses”. In 2026, some of Phonanium’s tools for Praat-based acoustic voice/speech analysis have been implemented in the broader platform provided by Cantaris.
Cantaris is not a medical device. It is a desktop application that records sound and reports acoustic measures of the voice signal, computed locally with Praat's open-source algorithms and stored encrypted on your own computer. It is not intended to diagnose, treat, cure or prevent any disease or condition. The interpretation of every result stays with the professional using it.
