For small businesses, serving customers who speak different languages can create an operational challenge that is difficult to solve through traditional hiring. A company may receive enough Spanish-language calls to lose potential customers, but not enough to justify employing a bilingual receptionist. Voice AI is emerging as an alternative to bridge that gap.
According to The State of Voice AI for Small Businesses 2026 report, 29% of surveyed US business owners said a language barrier during a phone conversation had already cost them a customer. The company’s analysis of 677,562 calls handled for 2,967 businesses between January 2025 and August 2026 also found that 13.4% of all calls were conducted in Spanish.
The findings highlight how multilingual capabilities are becoming a practical application of AI-powered customer service, particularly for businesses that cannot maintain dedicated language-specific support teams.
Spanish-language interactions are becoming part of everyday business operations
Among 1,102 businesses using an Upfirst AI receptionist with at least 50 calls, 90% had received at least one call in Spanish. While the volume varied, approximately one-third of these businesses handled Spanish-language interactions in at least 5% of their calls.
For smaller companies, this creates a staffing dilemma. Hiring a bilingual receptionist to handle occasional calls may not be financially viable, while failing to respond to Spanish-speaking customers can mean losing business opportunities.
Voice AI offers a way to manage these interactions without requiring companies to maintain separate teams for different languages. The report identifies multilingual call handling as one of the practical advantages of AI receptionists, particularly when language-specific demand is unpredictable.
The findings also point to broader consumer expectations around automated customer service. Upfirst found that 80% of consumers want an AI receptionist to disclose that it is artificial intelligence at the beginning of a call. Meanwhile, 70% are comfortable allowing AI to answer questions about business hours, services and pricing.
For businesses adopting these systems, language capabilities and transparency are therefore two relevant considerations when designing automated customer interactions.
The report, based on surveys of 270 US consumers and 262 small and mid-sized business owners, alongside real-world call records, suggests that voice AI is becoming a way to extend customer service availability and language coverage without necessarily increasing headcount.
