Private AI
What is private voice AI?
Private voice AI means the models that listen to your calls and decide what to say run on servers the provider operates, instead of sending every call to a shared, third-party AI API.
At NuTalk, that's how NuTalk SMB and NuTalk Call Center work: speech recognition and the language model run on our servers in Mexico and Texas, US. On pay per use, the language model runs on vetted cloud partners.

Your data
How we handle your data
No training on your conversations
We don't use your conversations to train general-purpose AI models. Your data trains a model only if you order a dedicated one.
Each workspace isolated
Every workspace is isolated from the others at the database level.
Recordings stored privately
Recordings and transcripts are stored privately, in the US.
The reply and scoring model keeps no copy
The language model that writes WhatsApp replies and scores calls runs on vetted cloud partners that don't keep the data or train on it. Or on NuTalk servers, for an extra fee. NuTalk keeps your conversation history and quality logs as described in our privacy policy.
A flat fee, not per token
On the flat plans we run the models, so an extra minute adds no model cost. Fair use applies: we review usage above 5,000 minutes a month per line.
Dedicated server or models
A voice server for your workspace alone, or models trained on your data, on our servers or yours. Both at additional cost.

FAQ
Private AI questions
Can I run self-hosted voice AI on my own servers?
Not the whole platform: NuTalk is a hosted service. On the flat plans, we operate the servers that run speech recognition and the language model for your calls. If you need models on your own servers, we can train dedicated models on your data and run them there, as a custom offer at additional cost.
Do you train AI models on my calls?
We don't use your conversations to train general-purpose AI models. Your data trains a model only if you order a dedicated one.
Which plans run on NuTalk servers?
NuTalk SMB and NuTalk Call Center. On both, speech recognition and the language model run on servers we operate in Mexico and Texas, US. On pay per use, the language model runs on vetted cloud partners.
Which models do you use?
On NuTalk SMB and NuTalk Call Center, we use speech recognition and a local LLM that we run on NuTalk servers, not a shared AI API. On pay per use, the language model runs on vetted cloud partners. We update the models over time and don't publish a model list. Voices come from cloud TTS.
Where are recordings and transcripts stored?
Privately, in the US. Each workspace is isolated from the others at the database level.
Is WhatsApp private too?
WhatsApp messages travel through Meta. The agent's replies are generated by AI models from vetted cloud partners that don't keep the data or train on it, or by NuTalk servers for an extra fee. NuTalk keeps your conversation history and quality logs as described in our privacy policy.
Can I get a dedicated AI server?
Yes. A voice server dedicated to your workspace is available at additional cost. Tell our sales team about your call volume.
