Duolingo Duet Challenge

Duolingo was entering the Philippines and needed to establish itself as the brand of choice for easy, fun language learning, in a market where English proficiency is high but many people still lack speaking confidence. Launching an English course in a country that already speaks English meant the campaign had to sell confidence and fun rather than basic proficiency. Vero's insight paired two behaviours: many Filipinos feel their speaking ability falls short despite high proficiency, and those already fluent often want to learn Korean, Spanish, Japanese or French, while karaoke is a pastime no Filipino can resist and songs teach pronunciation and vocabulary through rhythm and repetition.

Vero built Duolingo Duet, a karaoke challenge that asked learners to sing along to a beloved Filipino song in English, launched alongside the new Filipino to English course. The work ran as a full integrated marketing campaign, collaborating with micro and macro influencers chosen for singing ability, fun charisma that fits Duolingo's identity and strong follower engagement, supported by PR, media relations, content and activations. Anchoring the market entry in a local cultural ritual gave the launch a familiar, low-pressure way for Filipinos to take part, and casting influencers against specific criteria kept the challenge credible rather than purely paid.

Reframing an English course around speaking confidence rather than basic proficiency suited a market that already knows the language, and pairing the influencer challenge with PR and media relations extended the social mechanic into earned coverage. Vero reports the challenge was picked up and shared widely across social media and PR, encouraging app downloads, with the only published figure being 250 PR Points, an agency measure with no explained methodology. Every claim comes from Vero's own case study page, with no independent press or client statement, and the launch date and platforms are not stated, so outcomes should be read as self-reported.
