In the first post in this series, we established that brand naming has two unsolved problems: strategic evaluation and identity connection. Both require a common foundation — a way of measuring what a name actually does at the acoustic level.
That foundation is sound symbolism. And before explaining how the framework applies it, it's worth being precise about what the research actually says.
The Research Base
Sound symbolism — the non-arbitrary relationship between phonetic form and meaning — has been documented consistently across multiple independent research programs. The framework draws directly from five bodies of peer-reviewed work:
The question Klexaro set out to answer was not whether this research was credible — it is — but whether it could be made computable. Whether a system could implement these findings as a working evaluation engine, not just cite them as supporting references.
"Not what theory suggests a Modern brand should sound like — but what Apple, Stripe, and Slack actually have in common at the phoneme level."
The Five Dimensions of Any Brand Name
Applying this research computationally required decomposing every brand name into five measurable dimensions. Together, these produce what the framework calls a Sound Print — the complete phonetic signature of any name. Every name has one. The framework makes it visible and scoreable.
The textural backbone of a name. Different consonant categories carry documented perceptual qualities mapped from sound symbolism research. Voiceless plosives (P, T, K) signal sharpness and precision. Fricatives (F, S, SH, V, Z) signal modernity and velocity. Sonorants (M, N, L, R) signal warmth, continuity, and flow. Each consonant in a name is categorised and scored against the target profile's preferred consonant set.
The emotional resonance. Front vowels (IY, IH, EY, EH, AE) produce perceptions of smallness, brightness, sharpness and energy — per Klink (2000). Back vowels (UW, UH, OW, AO) produce perceptions of depth, warmth, weight and richness. Central vowels and diphthongs occupy the space between. Each vowel is mapped to its perceptual category and scored against the profile's target vowel set.
The perceived market positioning. Research by Pathak et al. (2019) confirmed directly that syllable count has measurable impact on brand perception across market tiers. One-syllable names (Slack, Stripe) signal directness and confidence. Two-syllable names balance accessibility with authority. Three-syllable names signal tradition and prestige. Each brand profile specifies a target syllable range, and the name is scored against it.
The rhythm and feel of a name spoken aloud. The system calculates a Euphony Score by measuring the ratio of hard consonant interruptions to continuous sounds — classifying each name as Smooth, Harsh, or Balanced. Smooth flow suits Luxury and Discovery profiles. Harsh flow suits Modern and Technical profiles. Balanced flow suits Professional and Playful profiles. The Euphony Score is a structural modifier on the final fit score.
Where the name's phonetic energy lands. Based on Murdock (1962) primacy and recency research, the system identifies whether a name is front-weighted (CHA-nel), end-weighted (ro-LEX), or balanced — and scores it against the target for its chosen profile. Front-weighted names are recalled by their opening sounds. End-weighted names leave their strongest impression last. Placement is not incidental — it is scored explicitly.
Does It Actually Work? Real Brands, Raw Scores.
One of the first validation steps was running established global brands through the Evaluate feature — brands whose market positioning is already well known — to test whether the phonetic scores matched commercial reality.
These are the raw results, straight from the app:
Rolex scoring 100% Technical — not Luxury — was a genuine surprise. The instinct is to assume Rolex sounds luxurious. At the phoneme level, its consonants (R, L, K, S) and vowel structure align more precisely with the Technical profile. Brand perception is shaped by many factors beyond phonetics: heritage, price positioning, marketing, distribution. What this framework measures is the acoustic dimension alone. That Rolex's acoustic signature is Technical, while its market positioning is Luxury, is a data point — not a contradiction.
The Sound Print — Making It Visible
Every name analyzed in Klexaro produces a complete Sound Print: its individual phonemes, scores across all seven brand profiles, and automatic collision detection output. Here is what that looks like in practice for a candidate name like Baksal:
This Sound Print is the raw phonetic data. The next post in this series explains what happens next — how the framework compares a name's Sound Print against a Brand Style Profile to produce a transparent, explainable Strategic Fit Score.
