Customer Support and Voice AI
AI receptionist for small business: calls, bookings and handoffs
What an AI receptionist does on a real call, the rules that apply, a sample greeting and a pass/fail checklist to launch one safely.
Inbound
AI Multilingual Voice Agent
One phone line that understands and replies in the caller's own language, detected automatically, not a translated script.
When a caller speaks a language your team does not, the call usually ends badly or goes to whoever happens to be free. This agent detects the caller's language from how they speak and runs the whole conversation in it, answering questions, booking and transferring. Each language uses content you approved, not a script translated on the fly.
- Detects the caller's language automatically, with no menu to press
- Runs each language from content you reviewed and approved
- Answers, books and transfers callers in their own language

Optional maintenance $345/mo
What it is
AI Multilingual Voice Agent answers your line and handles routine questions, bookings and transfers, in whichever language the caller speaks, detected automatically at the start of the call. Rather than a translated script, the conversation runs natively in the caller's language throughout.
Why businesses buy it
Callers who cannot be understood rarely call back. They take their booking, order or question to a business that speaks their language, and your team never knows what was lost. Hiring for every language is hard to sustain. This agent gives every caller the same quality of answer in their own language, at any hour, with transfers when a person is needed. The Scope Card sets the flows, systems and testing in writing before you order, so you know exactly what each language will cover.
Problems this solves
Callers who speak another language struggle to be understood
The agent detects the caller's language at the start of the call. The conversation then runs natively in that language, rather than through a translated script.
Only a few staff can take calls in other languages
Routine questions, bookings and transfers are handled in the caller's language by the agent. Your multilingual staff are kept for the calls that really need them.
Answers differ depending on which language the caller uses
Every language draws on the same approved source, up to 50 documents or an FAQ set. Callers get the same information whatever language they speak.
Bookings from non-English callers are often missed or garbled
Bookings are written into your connected calendar or CRM while the caller is still on the line. Details are recorded the same way, whichever language the conversation took place in.
A good fit if
A meaningful share of your callers speak a language other than your primary one, and staff coverage for that language is inconsistent.
You want the same call quality in every language you support, not a translated afterthought bolted onto an English script.
You already keep FAQs, hours and booking rules that could be delivered accurately in more than one language.
You want language detected automatically from how the caller speaks, rather than asking them to pick from a menu first.
Not the right fit if
You operate in a single language and do not expect that to change. See AI Voice Receptionist, the equivalent build for one language, with an Additional Language Pack, if that ever changes.
Your priority is troubleshooting depth over language coverage. See AI Voice Customer Support, which resolves support calls from your knowledge base in one language.
You mainly call people rather than receive their calls. See AI Outbound Calling Agent.
Your calls do not fit a receptionist-style script at all. See AI Inbound Call Agent, the flexible general-purpose base build.
How it works
- The call is answered and the caller's language is detected from how they speak, without asking them to select it first.
- The rest of the call, greeting, questions and answers, runs natively in that language, not as a live translation layered on top of an English flow.
- Routine questions are answered from the same FAQs and documents you approved, delivered accurately in the caller's language.
- Appointments are booked or changed against your live calendar, with confirmation details read back in the language the call started in.
- If a caller needs a person, they are transferred to the number you set for that language, so the handoff stays in language too.
- Every call is logged with a transcript, a summary and the language it was conducted in, written into your CRM.
What you provide within 72 hours
Your portal lists these the moment you order. Delivery starts the working day after everything is in and your access is checked.
- A telephony account in your name, such as Twilio, Vonage or Exotel, with the number this line should use.
- The languages you want covered, and any language-specific transfer numbers.
- Your call scripts, FAQs and business hours, ideally already reviewed for accuracy in each language you want covered.
- Access to your calendar and CRM, so bookings and call outcomes land in the right place regardless of language.
- Your preferred voice per language, and the recording disclosure wording for each.
- Admin access and API keys for every connected system, shared by adding our team as a user or creating a key you control, never by email.
- One person who can approve scripts and sign off test calls across every language included.
- An API key for your own AI model account (for example OpenAI or Google Gemini), created for this build with a spending limit.

Expected benefits and how to measure them
- More callers can be served in the language they are comfortable with.
- Multilingual staff can focus on complex calls.
- Answers can stay consistent across languages.
- Calls handled by language
- Use the agent's call log to count calls per detected language each week after launch.
- Abandoned non-English calls
- Ask staff to log calls dropped due to language for a month before launch, then compare with agent logs.
- Bookings from non-English callers
- Tag bookings by language in your calendar or CRM and compare monthly totals.
Before you start: Estimate how many calls each week come in other languages and how they are handled now. Note which staff currently cover them.
These are things to track, not promised results. Outcomes depend on your data, your team and your market.
Running costs
The build price is paid one time. Running it is billed in your own accounts, roughly $0.13 to $0.31 per call minute all in, covering the voice platform, the AI model and telephony, plus number rental, generally consistent across the languages configured. Total spend tracks combined call volume across every language on the line, not each language separately.
AI usage during build and testing is also billed to your own accounts, so every provider relationship stays yours.

Optional. Starts after the post-launch support period. Cancel any month.
How maintenance worksHow this compares
| Do it yourself with a SaaS tool | Hire a custom agency | Upmark Labs | |
|---|---|---|---|
| Price | A multilingual answering service charges a premium per-minute rate | A custom build gets quoted after discovery calls | Ours is one fixed price, shown on this page before you buy |
| Language handling | Often a live translator patched into the call | Depends entirely on what the agency scopes | Ours runs the conversation natively in the caller's detected language |
| Delivery | A translation-line service can take days to staff | An agency build usually runs several weeks | Ours has a fixed delivery time shown before you buy, with faster options |
| Call records | Summaries may only be written in one language | Depends on what was agreed with the agency | Ours logs the transcript and language for every call |
Questions about this product
How does the AI Multilingual Voice Agent know which language to use?
It listens to how the caller speaks at the start of the call and detects the language automatically, without asking them to select it from a menu first. The rest of the conversation, including questions, answers and confirmations, continues in that language for the whole call.
How is this different from adding the Additional Language Pack to the AI Voice Receptionist?
The Language Pack adds a second language on top of the Receptionist's base build, useful if you mostly need one language plus occasional coverage for another. This build is designed around multi-language handling from the start, with detection and native responses built into the core flow rather than layered on afterward.
Does call quality drop in a caller's non-primary language?
No. Each configured language runs its own reviewed flow, FAQs and voice, rather than a single script machine-translated on the fly during the call. You approve the content for each language during intake, so accuracy is checked and confirmed before launch, not assumed once the line goes live.
What does it cost to run the AI Multilingual Voice Agent each month?
Call minutes run roughly $0.13 to $0.31 all in, covering the voice platform, the AI model and telephony, plus number rental, paid directly in your own accounts. The rate is generally consistent regardless of which configured language a call uses, so your total tracks combined call volume across the line.
How long until it is live across all our languages?
The delivery panel on this page shows the timeline for each speed. The clock starts once you have approved the FAQs, hours, booking rules and disclosure wording for each language, plus system access. Fifty test calls then run across your languages, checking detection and accuracy, with two rounds of changes before callers reach the line.
Do callers know they are speaking to an AI in their own language?
Yes. The greeting includes a short disclosure delivered in the caller's detected language, using wording you approve for each configured language. Several US states and countries require this for automated calls, and the phrasing can be updated later through monthly maintenance.
Can we add another language after launch?
Yes. Adding a language beyond what was scoped at intake is handled as a Change Quote, since it involves new content review and testing in that language. Updates within an already-configured language, such as new FAQs, fit inside the monthly change hours included with maintenance.
