Cross-Recording Voice ID.
Sarah on Tuesday's iPhone recording is the same Sarah on Friday's iPad recording. One identity per person, every recording, every device.
On-device. Private. Never used to identify anyone outside your own library.
One identity per person — that's the unlock.
Most recording apps treat every meeting as an island. Sarah from Tuesday's call has nothing to do with Sarah from Friday's call as far as the app is concerned — even though they're the same person. That's why "what did Sarah promise me last week" doesn't work in those tools, and why a profile of how Sarah communicates over time can't exist.
Bonfiyah recognises Sarah across every recording she's in. One identity per person, regardless of which device captured her, when, or alongside whom. That single fact is what makes everything downstream — Promise Tracker, Speaker Insights, Pre-Brief, Team Dynamics — actually work.
The recognition also catches the silent-error case where two speakers with similar voices get merged into one label by the upstream transcription. We split them apart automatically, before you ever see the transcript.
What identity stability buys you.
Promise Tracker
"What did Sarah promise me last week" only works if Sarah is one identity, regardless of which device captured the recording. Voice ID is the precondition.
Speaker Insights · People Memory
A profile of every person you've recorded with is only coherent if "every recording with Sarah" is computable. Identity stability is what makes the profile real.
Compatibility Analysis
Pairwise frameworks (Attachment, Big Five, Gottman, Thomas-Kilmann) anchor to two specific identities. Mixed-up labels break this entirely; we won't run Compatibility on a recording with unresolved labels.
Team Dynamics
A team is a selection of identities, with placements anchored across many recordings. Identity stability is what makes the longitudinal read possible — watch Riley's placement migrate across a quarter only because Riley is one identity.
Privacy
Voice signatures are biometric data. We treat them that way.
Bonfiyah's voice recognition runs on our backend over a TLS-encrypted connection, using a purpose-built voice-recognition model tuned specifically for short, conversational utterances. The audio used to recognise a speaker is the audio of the recording you already authorised — nothing extra is captured, nothing is held longer than it takes to extract the fingerprint.
Voice signatures are biometric identifiers under GDPR, BIPA, and most modern privacy regimes. We treat them that way. Yours are stored under your account, sent only over HTTPS, and isolated from every other Bonfiyah user's library — there is no shared index and no "who is this voice on the internet" pathway. Unused signatures auto-purge after 90 days of inactivity. Delete a speaker manually any time, and the fingerprint goes with them.
Voice signatures are not the recording. They are a numerical fingerprint of the voice, and the original audio cannot be reconstructed from them.
Delete a speaker from your library and the signature is purged. Delete a recording and the signatures derived from it are purged with it. Uninstall Bonfiyah and the recognition system goes with the app — there is no off-device residue.
Where Voice ID will mis-recognise.
We're explicit about the edge cases because anyone using Bonfiyah for legal, medical, or research workflows needs to know them.
Siblings and identical twins
Voices that share substantial acoustic structure can be bound to one identity. Tap any line in the transcript to reassign — the fix persists across the library and future recordings.
Voice age drift
A child's voice changes substantially over months. A speaker entry that hasn't been refreshed in a long while may not match the same person today. The library updates on every successful match, so this resolves on its own with regular use.
Phone calls vs. in-room
A speaker on a low-bitrate phone call sounds different to the same speaker captured in-room. Bonfiyah handles most channel mismatches, but extreme cases (a cellular call vs. studio-quality lavalier) can need a manual reassignment the first time.
Tap to fix anything wrong
Every transcript line is one tap away from a speaker picker — pick the right person and Bonfiyah carries the correction forward. No support ticket, no menu diving.
FAQ
Can Voice ID be used to identify someone outside my library?
No. There is no global voice database, no cross-account index, no "who is this voice on the internet" pathway. Identity is scoped to your private speaker library, which is scoped to your iCloud. Bonfiyah is a memory layer, not a surveillance layer.
Where does the recognition run?
On our backend over a TLS-encrypted connection, using a purpose-built voice-recognition model. The audio used is the audio of the recording you already authorised — nothing additional is captured. Voice signatures are isolated to your account, never shared across users, and auto-purge after 90 days of inactivity.
What if Bonfiyah gets a speaker wrong?
Tap the line and pick the right person. The fix carries forward to every future recording, and any duplicate identities created by the mistake are merged. We also auto-correct the most common silent error — two similar voices merged into one label — before you ever see the transcript.
Is BIPA-style consent required?
In jurisdictions where biometric-data handling requires informed consent (Illinois BIPA, similar regimes), Bonfiyah's consent flow includes the voice-recognition disclosure as part of standard recording consent. We're not lawyers and this isn't legal advice; the disclosure is in plain language so you and your counsel can confirm it covers your jurisdiction.
Can I export my speaker library?
Yes. The export contains named identities and per-recording statistics. The underlying voice signatures are biometric data and don't export by default — there's an explicit "include voice signatures" toggle for portability or compliance scenarios, with a clear warning about what you're choosing to export.
