The language layer
Your business shouldn't need a different agent for every language.
You already built the workflow.
You already trained the agent.
You already connected the tools.
Why rebuild all of it because the next caller speaks Spanish?
BabelStream adds the language layer.
One process can answer in English, Spanish, French, Portuguese, Mandarin, or whatever comes next.
- 01Same business logic.
- 02Same integrations.
- 03Same outcome.
- 04Different language.
AI agents
Your AI agent just got a passport.
Take the voice agent you already have and let it communicate with customers around the world. BabelStream handles the language while your agent keeps doing its job.
Automations shouldn't have a native language.

Build the process once.
BabelStream lets the conversation happen in theirs.
Already have an AI agent? Good.We're not asking you to rebuild it.
Bring your agent. Bring your workflow. Bring your telephony. We'll bring the languages.
BabelStream can become the multilingual voice layer between your agent and the people it needs to reach.

What happens on every translated call
capabilities
From the first hello to the finished record, six parts of one translated line.
Interpret/01
Live interpretation
Live, two-way interpretation inside the call you already take. Both sides hear each other in their own language, and the conversation keeps flowing.
- Two-way, inside the live call
- Natural voice in both directions
- 60 languages callers can speak
- No interpreter to schedule
- No hold music while one is found
Route/02
One number

Connect/03
Your phone system
If it supports SIP, it works. BabelStream slots into the infrastructure you already run, with no replacement required.

- Existing desk phones and queues

- Conference: multilingual group calls
- Staff-controlled translation
Record/05
Every call, on record
Every translated call comes back as a record: the summary, the follow-ups, and a flag on calls that may need a second look.
- Transcripts and summaries
- Action items and follow-ups

Human translation
And sometimes, people just need to talk.
They speak theirs. You speak yours. BabelStream handles the middle.
No bot. No workflow. No AI pretending to be a person.
Just two people who don't speak the same language having a conversation anyway. BabelStream translates both sides of the call in real time while each person speaks naturally.

Still have questions?
Talk to sales and we will walk you through how BabelStream fits your phone system.
Talk to salesBabelStream is the language layer for voice. It gives human conversations, AI agents, and automated workflows the ability to communicate across 60 languages in real time, on the phone system you already run or in the BabelStream Connect desktop app.
Yes. Bring your agent, your workflow, and your telephony, and BabelStream brings the languages. One agent and one workflow can serve every customer, with no separate logic for every language.
Any team that serves callers in more than one language. That includes property management, healthcare, legal intake, customer support, the public sector, labor unions, education, hospitality, financial services, insurance, utilities, retail, logistics, home services, and many more.
No. BabelStream works with your existing SIP, PBX, and call routing. Your phones, queues, and numbers stay exactly as they are.
Interpreter services put a third person on the call, often after a wait on hold while one is found. BabelStream runs inside the call you already take, so both sides simply talk.
60 languages, including Spanish, Mandarin, Vietnamese, Portuguese, Arabic, French, Korean, and Hindi.
Yes. With the Intelligence add-on, every call comes back as a bilingual record, original and translated side by side, with a summary and the follow-ups your team owes.
BabelStream processes live audio to deliver translation during active calls. Signaling and service communication is encrypted in transit, retention is minimal by default, and retention policies can be customized to your requirements.
What every caller hears
Conversations that land, in every language.
From the first hello to the finished record, both sides hear their own language on the line they already use.
