Speak your customer’s language: the business case for multilingual AI Agent Customer Service

76% of shoppers prefer to buy products when information is presented in their native language. ¹

Studies show that many of those shoppers are more likely to return to a brand that offers support in their language.¹

Poor customer service and language friction come with real cost: research estimates that globally, bad customer experiences put US$ 3.7 trillion in sales at risk each year.²

These figures show that language access and quality support matter for conversion, retention, and long-term brand value.

Why multilingual AI agents are the strategic way forward

Offering multilingual support through Syllable AI agents is easy, and unlocks several advantages for modern businesses:

• You can meet customers’ expectations for native-language support without needing to staff large multilingual support teams.

• You reduce friction for non-native speakers, increasing the chance of conversion and repeat business when users can interact in their preferred language.

• You lower the risk of lost revenue or reputational damage from poor customer experiences, which are often driven by language misunderstandings.

• You scale support globally in a consistent, manageable way - across voice, chat, and web channels.

• It improves the customer experience, and customer experience matters, according to findings published by Fast Company, 86% of consumers will leave a brand after just two bad experiences.
