An agent that matches the caller’s accent
A caller in Manchester says “half two” where a caller in Chicago says “two thirty”. In the demo call, Artha opens in American English, the caller answers with a British accent, and Artha carries on in British English, saying “half past two” the way the caller would. On a live line, you set the agent up with the accent your callers expect.

An inbound call to a London dental practice, in US and UK English.
A short written sample to show the style of a British English call. It is not a recording of a customer call.
AI agent
Good morning, Harbour Dental, this is Artha. How can I help?
Caller
Hi, I chipped a tooth last night. Have you got anything this week?
AI agent
Sorry to hear that. We have Wednesday at quarter past nine, or Friday at four. Which suits you better?
Caller
Wednesday morning, please.
AI agent
Lovely. I have noted Wednesday at quarter past nine for a chipped tooth, and the team will confirm it with you shortly.
The caller’s name, the reason for the visit and the requested slot are saved on the call, so the practice team only has to confirm it.

What to get right before you go live in US and UK English.
- 1Step 1
1. Pick one accent per line
Choose the accent your callers expect: American for a US line, British for a UK line. If your callers are split between markets, use the accent of the main one, or set up a separate agent per number.
- 2Step 2
2. Dates, times and numbers
British and American callers say them differently: “the third of March” and “March third”, “half two” and “two thirty”, “oh” and “zero”. Run test calls that read out dates, times and phone numbers, and check the transcript before you go live.
- 3Step 3
3. Telephony and disclosure
Connect a number from your own telephony provider over SIP, or start with the website voice widget. Tell callers they are speaking with an AI assistant where your local rules expect it, and set a transfer or callback for anything the agent cannot answer.
US and UK English calls, handled end to end.
The questions buyers ask first.
What does it cost?
Usage is measured in minutes of conversation, and the voice and model you choose change how quickly minutes are used. Telephony is billed separately by the provider you connect.
How pricing worksHow much setup is it?
No code. Set the persona, prompt, voice and language, test it in the browser, then publish. Later changes apply from the next call.
Create an agentCan a person take over?
On phone calls the agent can dial in the colleague you set and stay on until they answer. Website calls take a callback request instead.
Functions and transferWhat if it does not know?
With strict mode on, it quotes your approved answers and says it will check with the team when something is not covered, rather than guessing.

Questions, answered.
The things people ask us most. If yours isn’t here, talk to us and a person will reply.
Ask us directlyYes. Vistrow Voice agents can speak natural American or British English, and in the demo call on this page the agent opens in an American accent and continues in a British one to match the caller. American and British voices are set up with you on request rather than picked from the self-serve voice list, so tell us which accent your callers expect.
Not on its own today. The demo shows what the voices can do; on a live line the agent keeps the voice and accent it was set up with. Most businesses choose the one accent their callers expect, American for a US line and British for a UK line. The agent still moves into another language, such as Hindi, if the caller does.
Yes. The agent answers your line or website call button at any hour, answers questions from your approved information, books appointments or callbacks and passes urgent calls to your team, with a transcript and summary of every call.
No. Telephony is bring your own: you connect a number from your own telephony provider over SIP, and overseas calling depends on that provider. The website voice widget works from any browser and needs no phone number.
Yes. The agent can speak English to customers abroad and move into Hindi, Punjabi, Gujarati or another Indian language if the caller does, which suits real-estate, education and financial-services firms with NRI customers.
Yes, as a first line or overflow: the agent answers routine calls, captures the details and hands complex calls to your human agents with a summary. Test it on your own call types and scripts before putting it on a client account.
You decide whether calls are recorded, whether spoken consent is required and how long call records are kept. If you work in a regulated sector, check your own obligations and ask us for our data-processing details before you go live.
