Articulance
Rehearse out loud.
Master your presence.
Say your pitch, keynote, or update once. Articulance measures how you actually delivered it on-device — your cadence, natural pauses, pitch dynamics, and vocal authority. Every coaching insight links directly to the exact second it happened so you can hear it, refine it, and speak with unshakeable confidence.

See one rehearsal,
end to end.
Twenty-five seconds, recorded on a real iPhone. Say a passage out loud, watch the measurements settle on your own device, then open a report where every coaching moment carries the second it happened and a button that plays it back.
- Rehearse with or without a script — the microphone keeps running behind a locked screen.
- Pace, pauses and pitch range are measured locally as you speak. Nothing is uploaded.
- Every note keeps its timestamp, its quotation and its own play button.
How Articulance reads a take
Effortless three-step coaching
No complicated setup. Speak naturally, get instant evidence, and sound your best.
Built for genuine transformation
Real speech coaching is about pinpointing what works and where to adjust — backed by verifiable evidence.
Live feedback that respects your focus
Keep your cadence in check with ambient, glanceable cues for pace, pauses, and pitch range. Designed specifically for peripheral awareness so you stay fully immersed in your narrative without distracting on-screen text flashing.
Calibrated to your voice, not a generic score
No arbitrary letter grades or vanity streaks. Great speaking isn’t one-size-fits-all. Every comparison is measured against your personal vocal baseline, helping you develop your authentic style rather than forcing an artificial standard.
Targeted preparation for real occasions
Whether it’s Friday’s executive update, a keynote address, or an interview, name your occasion once and every take gathers under that goal. See your run-up over time, compare your final delivery with your first take word-for-word against your script, and know you're ready.
Your acoustic blueprint
Explore the sound of your own rehearsals — pitch, pitch range, vowel space and articulation. Compare measurements with your own history when enough comparable evidence is available.
Fail-safe recording reliability
Rehearsal checkpoints are written locally while the mic is active. You can record with the screen locked. After an interruption, the app attempts to recover the last readable checkpoint on your next launch.
The Room & Second Take
Step into The Room to field tough, realistic spoken follow-ups about what you just presented. With Second Take, hear phrases that came across flat re-synthesized in your own voice with dynamic inflection.
Every insight comes
with an audio receipt.
Generic coaching apps tell you that you "sounded hesitant" and expect you to guess where. Articulance shows you the exact timestamp, quotes what you said, and gives you a single tap to listen right away.
Our on-device analysis links directly to your actual speech. When a phrase sounds monotone or rushed, you hear exactly how it came across in context so you can fix it effortlessly.
Honest diagnostics: If background noise or microphone distance affects a measurement, the app tells you clearly instead of displaying misleading numbers.
Pitch flattened on critical key figure
00:12Your pitch narrowed significantly across this sentence compared to your usual baseline. Expanding your vocal range here will emphasize this takeaway and command the room.

Real-Time Pace Nudge
Glanceable pace meter and live cadence coaching benchmarked against your natural rhythm. Live guidance prompts advise when cadence runs hot.
Paced Teleprompter
Follows your speech naturally rather than auto-scrolling at an aggressive speed. Keep your exact place without anxiety.
Voice Tuning & Warmup
A quick 30-second sustained note warmup evaluates vocal clarity, tone steadiness, and pitch stability before your big presentation.
Timestamped Coaching Receipts
Twelve types of coachable moments categorized by impact. Tap any card to hear the verbatim audio snippet immediately.
Full-Take Interactive Replay
Pitch columns and speech rails visually depict your energy, pauses, and cadence across the entire duration of your speech.
Complete Acoustic Grid
Every measurable dimension: words per minute, filled pauses, pitch modulation, volume range, and breath placement.
Personal Speaker Marks
Add your own personal notes at any second while listening back. Keep your own observations alongside algorithmic feedback.
Occasion Hub & History
Organize multiple rehearsals for key milestones. Search past sessions by transcript keywords or delivery style.
Iterative Coaching
The coaching engine compares each take against your prior attempts so you see exactly how your delivery improved.
The Event Run-Up
A post-event retrospective showing how many takes you delivered, how your pacing stabilized, and script word changes.
Persistent Verified Receipts
Revisit sessions months later with verified quotes and insights preserved permanently in your local history archive.
Your Voice Baseline
Your resting vocal pitch, usual speech rate, dynamic range, and four core channels of vocal authority mapped cleanly.
Executive Presence Radar
Acoustic evaluation of Gravitas, Conviction, Charisma, and Effort mapped against your self-relative baseline.
The Room — Spoken Q&A
Practice tough executive Q&A sessions. Spoken AI personas ask realistic follow-ups grounded directly in what you presented.
Second Take
Hear flat phrases re-voiced with dynamic pitch modulation in your own voice and timbre. Hear the difference immediately.
The same measurements, at iPad size
One purchase covers iPhone and iPad. At the wider size the layout is its own composition — a persistent sidebar beside a reading column that stops at a comfortable measure, rather than a phone screen stretched across a tablet.
Ten dimensions of speech precision
Acoustic physics and local speech intelligence working seamlessly on your iPhone.
Pace & Cadence
Overall speaking rate compared with active speech time, so you can compare this take with your own earlier rehearsals.
Strategic Pauses
Shows pause durations and locations in your transcript so you can listen to what happened.
Pitch Dynamics
Measures your overall pitch range and phrase-level inflection in semitones against your own earlier rehearsals.
Filler Words & Hesitations
Detects filled pauses ("um", "uh") acoustically and linguistically with timestamps you can listen against; detection is imperfect.
Word & Phrase Emphasis
Pinpoints the exact words you leaned into with energy and pitch, highlighting whether your main points received focus.
Vowel Articulation
Estimates vowel-space movement and vocal-tract shape from supported recordings, and declines when the signal cannot support a reading.
Phrasing & Energy
Measures pitch and level movement within phrases, including rising and fading endings.
Breath Timing
Shows detected inhalations and where they fall relative to phrase boundaries; quiet breaths may be missed.
Voice Stability
Measures cycle-to-cycle vocal steadiness, acoustic resonance, and pitch wander without assigning a good or bad direction.
Executive Presence
Acoustic cues synthesize into four core pillars: Gravitas, Conviction, Charisma, and Effort relative to your baseline.

Frequently asked questions
Direct, straightforward answers to everything you want to know.
Articulance processes your speech locally and never uploads it. There is no developer backend, analytics tracker or account. You control any recordings, images or messages you choose to export. App Store downloads, browser links, support messages and destinations you choose for exports can use a network. Articulance never uploads your speech.
Rehearsal and Room answer recordings are kept on this phone by default, with a notice before your first recording under this setting. They are never uploaded or included in device backups. Turn off Keep audio for replay in Settings at any time; an existing off choice is preserved. With keeping off, rehearsal audio is deleted when its fresh report closes and Room answer audio is not saved. Kept recordings remain yours to replay or delete. Kept recordings are available in Files; copies you export are managed by the destination you choose.
Because communication is contextual, personal, and human. There is no universally "perfect" pitch or speech rate for all occasions. A somber eulogy requires a different delivery than an energetic startup pitch. Instead of superficial game mechanics and grades, Articulance benchmarks your performance against your own baseline so you can see tangible, authentic growth over time.
Everything. One purchase includes unlimited rehearsals, all ten acoustic metrics, the live feedback HUD, post-session reports, timestamped audio playback, full session history, your personal voice print baseline, The Room, scripts and the teleprompter, re-take drills and the executive debrief. No subscription, no accounts, no watermarks, and no usage caps.
Yes. Name your occasion (e.g. "Series A Pitch" or "Q3 All Hands") and every rehearsal you do for it collects under that tag. After the event, your run-up report shows how your pacing settled, how many takes you delivered across the week, and verbatim word comparisons against your script.
The app checkpoints the rehearsal while recording. Articulance supports iOS background recording with local checkpoints. You can rehearse a 20-minute presentation with your phone face down. If capture is interrupted, the app attempts to recover the last checkpoint on your next launch. The last unsaved interval may be missing, and recovery needs a readable checkpoint and enough storage.
Yes — once Apple's on-device speech assets for your language are installed. iOS may download them the first time transcription is needed. Without them, acoustic measurements still work; transcription and word-based notes wait for the assets. Once installed, no network is needed for your rehearsal.
