What this means for learners

Spanish and Catalan share 25 sounds — roughly 56% of Catalan's inventory overlaps with Spanish. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.

The 14 sounds found only in Catalan represent the greatest pronunciation challenge for Spanish speakers. The adult brain tends to map unfamiliar sounds onto the closest native equivalent — a process that produces the characteristic "accent" of a second-language speaker. Learning to hear and produce these sounds as distinct requires focused ear training, not just repetition.

Conversely, Spanish has 20 sounds not used in Catalan. Native Catalan speakers learning Spanish will face the mirror-image challenge with these sounds.
