TLDR: Yes. Otto auto-detects the caller's language and responds in that language without requiring the caller to press any buttons or navigate a menu. The Growth plan supports 3 languages. The Pro and Unlimited plans support 10 or more languages, covering Mandarin, Vietnamese, and other languages common in Australian multicultural communities.
If your restaurant is located in a suburb with a large Mandarin, Vietnamese, or other non-English speaking community, the phone is probably your most important customer channel for those customers. Many prefer to order in their first language, particularly older callers who are less comfortable with English-only automated systems or smartphone apps. An AI phone agent that cannot handle their language is not an asset. It is a barrier.
This article explains how multilingual AI phone ordering works, which languages are available, and what the no-button-press detection means in practice for your customers.
Yes, and the way Otto does it matters as much as the fact that it does it. Otto does not ask callers to press a number to select their language. It listens to how the caller begins speaking and responds in that language automatically.
This distinction is significant for two reasons. First, older callers and those less comfortable with technology are often put off by automated menu systems. A prompt that says "press 1 for English, press 2 for Mandarin" creates a barrier before the conversation has started. Second, callers in diverse communities often mix languages naturally. Auto-detection handles this more gracefully than a forced selection at the start of the call.
The language capability is built into Otto at the product level. It is not a translation service layered on top. Otto understands ordering context across languages, meaning it handles modifier requests, confirmations, and corrections in the caller's language without reverting to English for the technical parts of the transaction.
Language support varies by plan. The Growth plan at $299 AUD per month supports 3 languages. The Pro plan at $599 AUD per month and the Unlimited plan at $999 AUD per month support 10 or more languages.
For a Thai restaurant in an area with large Mandarin and Vietnamese-speaking communities, the practical question is which languages your customers actually use. If three languages covers your community, the Growth plan is sufficient. If your suburb has a broader multilingual mix, the Pro or Unlimited plan gives you the wider coverage.

For a restaurant serving an older Vietnamese-speaking community, a customer who calls and hears "press 1 for English, press 2 for Vietnamese" has already encountered a hurdle. Many will hang up and call a competitor or simply not order. The friction is small by tech standards but meaningful for a customer who was not expecting to navigate a phone menu.
Otto removes that hurdle. The caller dials the same number they always have. Otto answers and responds to however they open the conversation. If they start in Vietnamese, Otto responds in Vietnamese. The experience from the caller's side is that someone answered the phone and understood them.
This also applies to callers who speak both English and their first language but feel more comfortable placing a complex order, with specific modifications and additions, in the language where they are most precise. Getting an order exactly right is easier when you can express it naturally.
The Otto Restaurant Phone Report 2026 found that restaurants miss around 1 in 3 calls on average, with over 70% of those missed calls being revenue-related. For venues in multilingual communities, a system that only handles English effectively is missing a segment of that revenue on every service.
A Thai restaurant in Springvale, Footscray, or Cabramatta that can handle Mandarin, Vietnamese, and Cantonese calls reliably is accessible to its entire customer base, not just the English-speaking portion of it. That accessibility directly affects how much of the available demand the venue actually captures.
Yes. Otto auto-detects the caller's language and responds in that language without requiring any button-pressing. The Growth plan supports 3 languages. The Pro and Unlimited plans support 10 or more languages, covering Mandarin, Vietnamese, and other languages common in Australian communities.
No. Otto listens to how the caller begins speaking and responds in that language automatically. There is no menu selection required. A caller who opens in Vietnamese receives a response in Vietnamese without any navigation.
The Growth plan at $299 AUD per month supports 3 languages. If your community speaks primarily two or three languages beyond English, this plan covers it. The Pro and Unlimited plans support 10 or more languages for venues serving broader multilingual communities. Full details at callotto.ai/pricing.
The specific languages supported depend on the plan. The Pro and Unlimited plans support 10 or more languages. To confirm which specific languages are included for your location and customer base, contact the Otto team during onboarding. Language support is confirmed as part of the setup process.
Many customers, particularly older ones, prefer calling regardless of available alternatives. Familiarity with calling, comfort with phone conversations for complex orders, and the personal feel of speaking to someone are all reasons callers in multilingual communities tend to use the phone. An AI phone agent that handles their language meets them where they already are.
Otto handles multiple languages with auto-detection, meaning callers do not need to press any buttons to be served in their language. For Australian restaurants in diverse communities, this is a direct revenue capability.
