Short answer
For routine calls such as hours, directions, bookings and FAQs, yes. Expect weaker accuracy with strong Singlish and mixed languages, so always offer a quick hand-off to a person. Platforms charge roughly US$0.07 to US$0.31 a minute, plus phone line costs.
What an AI phone receptionist actually does
An AI voice receptionist answers your business number, listens, works out what the caller wants, and replies in a synthetic voice. Behind it are three parts: speech recognition that turns the caller's words into text, a language model that decides what to say or do, and text-to-speech that speaks the answer. Some newer systems handle speech directly without the text step.
- Answering FAQs: opening hours, location, parking, prices, services offered.
- Bookings: checking availability and creating, moving or cancelling appointments in your booking system.
- Message taking: collecting name, number and reason for calling, then sending a summary by email or WhatsApp.
- Routing: transferring to a person for urgent, sensitive or complicated calls.
- After-hours cover: answering when the office is closed instead of voicemail.
If your customers mostly message rather than call, a website or WhatsApp assistant may give better value. Our guide to AI chatbots for Singapore websites covers that route.
Singlish and accents: what published tests show
This is the real question for Singapore. We have not run our own tests, but A*STAR's MERaLiON team publishes word error rates for several speech models on Singapore-accented test sets. On its MERaLiON-2 model card, OpenAI's open Whisper large-v3 model averaged about 25% word error rate on Singlish test sets against about 8% on English sets. MERaLiON's own Singlish-tuned speech model averaged about 13% on Singlish.
| Model (from MERaLiON-2 model card) | Average word error rate: English | Average word error rate: Singlish |
|---|---|---|
| Whisper large-v3 (OpenAI, open model) | About 8% | About 25% |
| MERaLiON-2-10B-ASR (A*STAR) | About 8% | About 13% |
Two practical lessons follow. First, a general model can mishear a significant share of words when callers speak casual Singlish or switch to Mandarin, Malay or Hokkien mid-sentence. Second, names, addresses, NRIC-style codes and phone numbers are where errors hurt most. Design the agent to read back key details and confirm them, and test with real recordings from your own customers before going live.
What AI voice receptionists cost per minute
Most platforms charge per minute of conversation. Prices below are each vendor's published US-dollar rates, approximate, as of October 2026. They usually exclude the phone number and carrier call charges.
| Platform | Published price | Notes |
|---|---|---|
| Retell AI | US$0.07 to US$0.31 per minute | Pay as you go; rate depends on voice and AI model chosen (pricing) |
| ElevenLabs Agents | US$0.08 per minute | Speech models in one agent pipeline (API pricing) |
| Vapi | Usage-based per component | Speech recognition, AI model and voice billed separately (pricing) |

PDPA: recording, transcripts and telling callers
A voice agent collects personal data: the caller's voice, number, name and whatever they say. The PDPA requires you to notify people of the purposes and obtain consent before collecting their data, protect it, and keep it only as long as needed.
PDPA set-up for an AI receptionist
Most voice platforms are based overseas, so call data may be stored outside Singapore. Under the PDPA's transfer rules you must ensure overseas recipients protect it to a comparable standard, usually through the vendor's contract terms.
Outbound calls and the Do Not Call Registry
Some platforms also make outbound calls for reminders or sales. A reminder about an existing appointment is a service call. A call offering a promotion is a marketing message, and Singapore's Do Not Call rules apply: you must check Singapore numbers against the DNC Registry before sending marketing calls or messages, unless you have the person's clear consent.
Connecting it to bookings, and when to hand off to a person
The value comes from doing something, not just talking. A useful receptionist reads and writes to your booking calendar, sends confirmations, and hands over cleanly when it cannot help.
List your top call reasons
Check a week of calls. Usually five or six reasons cover most of them: bookings, changes, hours, prices, directions, results.
Connect the booking system
Use a system with an API or a supported integration so the agent can see real availability. Our guide to choosing a booking system covers options.
Write the script and limits
Give the agent approved answers, prices and policies. Tell it what it must never do, such as give medical, legal or financial advice.
Set hand-off rules
Transfer immediately for complaints, emergencies, payment problems or when the caller asks for a person or the agent fails to understand twice.
Test with real voices
Have staff and a few customers call with different accents, background noise and mixed languages. Fix the misunderstandings before launch.
Review transcripts weekly
Read a sample of calls in the first month, update answers, and track how many calls needed a person.
Do it yourself or get help?
Platforms such as Retell, ElevenLabs and Vapi let a technical owner build a basic receptionist in a day. The hard parts are the booking integration, accurate scripts, hand-off rules, PDPA notices and testing with real Singapore accents.
Our AI Website Assistant (S$790) sets up an AI assistant trained on your own answers, and we can scope a phone version on the same knowledge. If your bookings are still by phone and paper, start with an Online Booking System (S$390), which any AI receptionist or chatbot can later connect to.
Frequently asked questions
Partly. Published tests by A*STAR's MERaLiON team show general speech models such as Whisper large-v3 making roughly three times as many word errors on Singlish test sets as on standard English. Models tuned for Singapore do better. Design the agent to confirm key details and hand off to a person when it misunderstands.
Platform usage is typically charged per minute. As of October 2026, Retell AI lists about US$0.07 to US$0.31 a minute and ElevenLabs Agents about US$0.08 a minute, before phone number and call charges. Set-up, integration with your booking system and ongoing script updates add to the total.
It is good practice and supports your PDPA notification duty. Tell callers at the start that they are speaking with an AI assistant, whether the call is recorded or transcribed and why, and how to reach a person. Clear notice also reduces frustration and complaints when the agent makes a mistake.
It can, but Do Not Call rules apply exactly as they do to human callers. Before marketing calls to Singapore numbers, check them against the DNC Registry unless you have clear consent, keep consent records and offer an opt-out. Appointment reminders for existing customers are generally service calls rather than marketing.
Complaints, emergencies, payment or billing disputes, anything needing medical, legal or financial judgement, and callers who ask for a person. Set the agent to transfer immediately in those cases, and also after it fails to understand the caller twice. Review transcripts regularly to spot other call types that need a person.
