Most AI receptionists answer Spanish callers for free — two notable holdouts charge for it
Spanish-English bilingual answering is table stakes for most of this market and costs nothing extra; the exceptions are Slang.ai, which gates it behind a $99/mo add-on, and PATLive's live agents at $20/mo.
Updated 2026-09-09 — the index gained a vendor, this cohort did not. The dataset now holds 25 vendors, and the newest of them prices below everything in this guide: CallSprout Sage lists $22.95 per user seat per month. It is deliberately absent from the table below, and it does not move this guide’s floor. Neither its pricing page nor its voice-agent page makes a Spanish, bilingual or language claim of any kind — which is the one thing every row here has to publish — and its price buys a seat, not a business, so a five-person office starts at $114.75/mo before its $0.39/min Sage meter (free for the first 30 seconds of every call) runs at all. The cheapest bilingual base is therefore still Upfirst and AIRA at $24.95/mo. Everything else stands as re-verified 2026-06-22: all seven “included” vendors still fold Spanish into the base price, and both holdouts are confirmed — Slang.ai still gates Spanish behind a $99/mo add-on on Core (Premium $599/mo bundles it), and PATLive still bills bilingual answering at $20/mo. One PATLive correction rides with this pass: the 2026-09-02 re-read cut Basic from $75 to $49/mo (still no included minutes) and Standard from $460 to $349/mo for 200 minutes, so the PATLive figures below are the September ones, and its cheapest entry is the Basic plan rather than the Standard tier this guide uses as its example. Two honesty notes carried over: My AI Front Desk and Thoughtly publish a language count (“20+”, “34+”) rather than naming Spanish — it’s covered, just not called out by name.
If your callers switch between English and Spanish, the good news is that bilingual answering is no longer a premium feature in this market — it’s the default. Seven of the AI receptionists in our dataset handle Spanish-speaking callers at no additional charge, starting from Upfirst and AIRA at $24.95/mo — the cheapest bilingual base in the index, though no longer its cheapest sticker — then Dialzara at $29/mo and Rosie at $49/mo. Two vendors are the exception: Slang.ai treats Spanish as a $99/mo add-on on its entry Core plan, and PATLive, a live-human service, bills bilingual answering as a $20/mo add-on. Everywhere else, the language column is already paid for.
Spanish is bundled by default
The vendors that state English and Spanish support fold it into the base price with no line item attached. Here is where bilingual answering starts on each, using the lowest plan we can price:
| Vendor | Bilingual cost | Entry plan | What’s stated |
|---|---|---|---|
| Upfirst | included | Starter $24.95/mo | 35+ languages |
| AIRA | included | Starter $24.95/mo | 74 languages, EN/ES |
| Dialzara | included | Business Lite $29/mo | English + Spanish |
| Rosie | included | Professional $49/mo | English & Spanish on every call |
| Abby Connect | included | AI Starter $99/mo | Trained for English & Spanish |
| My AI Front Desk | included | Business-in-a-Box $99/mo | 20+ languages |
| Thoughtly | included | Flex $500/mo | 34+ languages |
The spread between these — from Upfirst and AIRA at $24.95/mo to Thoughtly’s $500/mo Flex plan — has nothing to do with language and everything to do with included volume, integrations, and target customer. Rosie is unusually explicit that it speaks “English & Spanish on every call,” which matters operationally: you don’t pick a language at setup, the agent handles whichever the caller uses. For a buyer whose only requirement is “answer Spanish callers without a surcharge,” the entry plans from Upfirst, AIRA, and Dialzara clear the bar for under $30/mo. One honest caveat on two of these: Rosie, Dialzara, Abby Connect, Upfirst, and AIRA name English and Spanish explicitly, while My AI Front Desk and Thoughtly publish only a language count (“20+” and “34+”) — Spanish is certainly inside that range and carries no add-on, but the page doesn’t call it out by name the way the others do.
The cheapest sticker in the index is not on this table
Worth saying plainly, because the index moved underneath this guide: $24.95/mo is the cheapest bilingual base here, not the cheapest base we track. On 2026-09-09 the dataset took in a 25th vendor, CallSprout Sage, whose entry Business plan lists $22.95 per user seat per month — below Upfirst and AIRA. It is not in the table above, for two reasons that are worth separating. The first is the entry requirement: neither CallSprout’s pricing page nor its Sage voice-agent page makes any Spanish, bilingual or language claim at all, and this guide only lists what a vendor publishes. That is the same rule that lets My AI Front Desk and Thoughtly in on a language count — a count is a claim; silence is not. The second is that $22.95 buys one seat, not one business, which is how every other price on this page is quoted: a five-person office starts at $114.75/mo, and Sage’s minutes then meter at $0.39/min after a free first 30 seconds on each call. So the sticker undercuts the bilingual floor and the bill does not, and in any case a Spanish-speaking caller is not something CallSprout has told us Sage will handle.
The two vendors that charge — and why the math differs
Slang.ai is the one case where bilingual support meaningfully bends the price. Its Core plan is $399/mo per location with Spanish offered as a $99/mo add-on, so a single-location restaurant that needs Spanish pays $498/mo — the add-on is a 25% surcharge on top of the base. Slang’s own escape hatch is to move up: the Premium plan at $599/mo includes Spanish, which means the gap between “Core plus Spanish” and “Premium with Spanish bundled” is just $101/mo for the rest of Premium’s feature set. Restaurants that genuinely need bilingual answering are effectively nudged off Core.
PATLive charges too, but the comparison isn’t apples-to-apples — PATLive answers with live human agents, not AI. Its $20/mo bilingual add-on sits on top of per-minute receptionist plans. PATLive’s cheapest entry is its Basic plan at $49/mo (which carries no included minutes), but on the Standard tier at $349/mo for 200 included minutes, the add-on lands at a $369/mo all-in figure, a roughly 6% uplift. That is a far gentler surcharge than Slang’s in percentage terms, and it buys human bilingual agents rather than an AI voice — a different product at a different price point entirely, and one we size up in AI vs human receptionist cost.
How to read this
For Spanish-English answering, language should rarely drive your shortlist, because most of this market gives it away. The decision collapses to the same questions you’d ask without the bilingual requirement: included volume, integrations, and billing model. The only places where Spanish changes the arithmetic are Slang.ai, where the $99/mo Core add-on (or the jump to $599/mo Premium) is real money for a restaurant, and PATLive, where the $20/mo add-on is the price of human agents rather than AI. Everywhere else — Rosie, Dialzara, Upfirst, AIRA, My AI Front Desk, Abby Connect, Thoughtly — the Spanish-speaking caller is already covered in the sticker price you were going to pay anyway.
