Set a voice per language on a call bot
One agent, right accent. Voice lives on the bot — never on a campaign or a channel — and the tier you get depends on your plan.
Voice is set per language, on the bot. Not on the channel it answers, not on the campaign that dials — on the bot itself. This is the same principle as everything else about bots: the bot owns how it behaves, and the things pointing at it only decide when it is used.
The practical consequence is that one agent can sound right in more than one market without duplicating it. The other consequence is that if you need genuinely different voices for the same language in different campaigns, you need two bots.

Before you start
- A call bot, not a chat bot.
- Awareness of your plan's voice tier.
- Somebody who speaks each language you are enabling.
Steps
Open the call bot and find the voice settings
Only call bots have them. If you cannot find them, check the Type — you are probably looking at a chat bot.
Add only the languages you can support downstream
A bot that converses beautifully in Hindi and then hands over to a team who cannot has made the experience worse, not better. Enable a language when the handover works in it too.
Pick a voice per language
The tier available depends on your plan: standard on Starter, human-like on Pro, premium on Growth, ultra-realistic on Scaler.
Listen to each voice saying your actual first message
Not a generic sample. Your opening line, with your brand name in it. Brand names are exactly where synthetic voices most often break the spell, and you will hear it immediately.
Test the things you say every day
Prices, phone numbers, street names, appointment times. These are where pronunciation fails in ways that cost you bookings, and they are testable in about two minutes.
Fix pronunciation in the instruction
Spelling a difficult name phonetically in the instruction usually fixes it. This is the practical workaround and it works well enough that it is worth doing rather than accepting a mispronounced brand.
Confirm the switch mid-call
Have somebody change language partway through a call and listen to the seam. A clean switch is impressive; a bad one is the moment the caller realises they are talking to a machine.
Check it worked
Record one call per language and play it to somebody who speaks it natively. Ask them one question: would you keep listening? That answer is worth more than any setting.
The parts people get wrong
- A campaign cannot override the voice. If you need a different voice, you need a different bot.
- Because voice is per language on the bot, the same agent can serve two markets from one configuration.
