Phonetic analysis for brand names, baby names, and anything that needs to sound right
PhonoPair scores how words sound together using structured linguistic databases — not AI guesswork. Every factor is named, sourced, and explainable.PhonoPair is a free phonetic brand name analysis tool. Enter 1–5 words and get a 0–100 score across three pillars — Phonetic, Language, and Semantic — with a named factor breakdown explaining exactly why a name works or doesn't.
It also generates names, checks domain availability, explores the dictionary by phonetic quality, and produces shareable score cards. The full analyzer runs without an account.

Full analyzer accessible without sign-up — accounts unlock saved results and historyThe scoring engine is built on the CMU Pronouncing Dictionary (~135,000 entries) for phoneme extraction, Natural NLP for language pattern detection, and ConceptNet + Wikipedia APIs for semantic and cultural associations.
Three independent pillars produce a 0–100 blended score. Each pillar is broken into named bonus and penalty factors — alliteration, vowel harmony, hard consonant clusters, cross-language issues, and 13 others — each with a confidence value. The result is fully explainable: you can see exactly which factors drove a high or low score.

Every factor scored by PhonoPair maps to published findings in psycholinguistics, cognitive psychology, and branding science.

PhonoPair started as an internal tool. We were running brand naming engagements — shortlisting 40+ candidates, pressure-testing them with clients, validating internationally — and doing the phonetic analysis by hand. It was slow, inconsistent, and hard to defend in a room.
So we built a scoring engine. Deterministic, documented, grounded in linguistic research. It became the backbone of every engagement we ran. Then we made it public.
The tool is free to use. The expertise behind it isn't — but if you have a naming problem that needs more than a score, we'd like to hear about it →
Brand naming practitioner with a background in linguistics, brand strategy, and digital product design. Previously led naming and identity projects at Liiift Studio across fintech, climate tech, consumer goods, and SaaS. Built PhonoPair after spending too many hours doing phonetic analysis by hand — and realising the process needed a scoring engine, not another spreadsheet.
PhonoPair was built to run phonetic analysis faster on real naming projects. We still take on select custom engagements — brand naming, naming audits, and international validation.
