This paper examines the sound-symbolic link between voiced obstruents (speech sounds created by obstructing the airflow) present in a brand name and the perceived product/brand attributes. In three studies (two using self-reported measures and one using an implicit reaction time paradigm), we tested the effect of voiced (b, d, g, z, v) versus voiceless obstruents (p, t, k, s, f) across 25 hypothetical brand names, on the perceived product attributes of harshness (vs. softness). Brand names with voiced (vs. voiceless) obstruents are perceived as harsh (vs. soft/mild). Results are described across two different product categories (e.g., toilet cleaner and skin conditioner), and also within the same product category (e.g., strong vs. light bee...
