Chat vs voice
Typed or spoken: which does your business need?
They use the same knowledge and run in the same widget, so this isn't really a versus. The question is which one you switch on first, and that depends on what your customers are doing when they ask.
The difference, shown
Same question, two ways to answer it
Notice what changes and what doesn't: the interaction is different, the knowledge behind it is identical.
- Do you take walk-ins on Saturdays?
- We do, but Saturdays fill up fast. I can hold a slot for you now. Would 10:00 or 1:30 suit you better?
- 1:30 works.
- Booked for Saturday at 1:30 pm. I've sent a confirmation to your email.Appointment created
Listening. No phone call, no app
- Hi, how much is a full colour treatment?
- A full colour is ninety-nine dollars and forty-five cents, and it takes about two hours.
- Can I book that for Thursday?
- Thursday has an opening at 11 am. Shall I put you down for that?
Line by line
How they actually differ
Where a row says the same thing twice, that's the point. Both modes share one knowledge base and one booking system.
| Question | AI chatbot | AI voice agent |
|---|---|---|
| How the visitor interacts | Types into a widget on your site. Can read back what was said and copy details out of it. | Speaks, using their microphone, inside the same widget. Nothing to install and no number to call. |
| Best when | The answer contains something worth keeping, such as a price, an address, a list of options or a booking reference. | The visitor's hands are busy, they're on a phone, or typing feels like too much effort for one question. |
| Speed of an answer | The full reply arrives as one message. | Audio starts before the sentence is finished, and you can interrupt it mid-reply. |
| Where the answers come from | The same uploaded documents. | The same uploaded documents. |
| Appointment booking | Yes. It uses real availability and locks the slot as it books. | Yes. It uses the same booking logic and confirms the time out loud. |
| Lead capture | Yes, by email to your team. | Yes, by email to your team. |
| Guard against invented figures | Answers are written from retrieved passages of your material. | The same, plus an explicit check that blocks unsupported numbers and names before anything is spoken. |
| Works without sound | Yes. Nothing to hear, nothing to permit. | No. Needs a microphone and the visitor's permission, and somewhere they can talk. |
| Accessibility fit | Better for deaf and hard-of-hearing visitors, and in noisy or public places. | Better for visitors with low vision, dyslexia, or limited dexterity. |
| Cost per conversation | Lower because it uses text only. | Higher because transcription and speech generation both cost per minute. |

Choosing
A simple way to decide
Start with chat if…
- Your answers include prices, addresses or reference numbers people need to keep
- Most of your traffic browses at work or somewhere quiet
- You want the widest reach with the fewest permissions
- Cost per conversation matters more than novelty
Add voice if…
- Your customers are often mid-task, driving, on site or working with their hands full
- Your audience skews towards people who would rather talk than type
- Your questions are quick and conversational rather than detailed
- Standing out from every other site in your sector is worth something
In practice most accounts run chat first, then add voice once the knowledge base has been through a few weeks of real questions. Voice makes any gap in your material much more obvious.
FAQ
Chat vs voice: common questions
No, and most businesses shouldn't. Both run in the same widget with the same knowledge, and the visitor picks. The real question is which one you turn on first. Chat is the safer default because it works everywhere and costs less per conversation.
We won't quote you a number, because we don't have one worth quoting. What we'd say is that it depends on context: voice tends to suit quick, decisive questions from people already leaning towards booking, while chat suits detailed comparison where someone wants the answer written down.
Not if it's built properly. Voice has to handle being interrupted, avoid transcribing its own output, start speaking before the sentence is finished, and pronounce prices the way people say them. None of that exists in a text chatbot.
Yes. Chat costs are text-only, while voice pays for transcription and speech generation per minute on top. That's why voice sessions have length and concurrency limits, and why it sits on a higher plan.
Chat is always there in the same widget. That matters for deaf and hard-of-hearing visitors, anyone in a noisy or public place, and people who simply don't want to talk to their laptop in an open-plan office.
