Today, PRAIX is introducing Lingua V2, a new voice engine built for seamless cross-lingual conversational AI and agentic workflows.

Speaking multiple languages is no longer enough.

For a voice conversation to feel truly natural, an AI agent needs to do more than translate words. It needs to understand the language being used, adapt to the conversation, and sound natural in the way that language is actually spoken.

That is what Lingua V2 is built to do.

More than speaking the language

Lingua V2 supports 29 languages fluently, but its key focus goes beyond language coverage.

The engine is designed to deliver natural regional accents, helping AI agents sound closer to a local speaker rather than simply producing a translated version of the same voice.

For businesses serving customers across different countries and linguistic communities, that distinction matters.

A customer should not have to adjust the way they speak simply because they are talking to an AI agent.

Switch languages naturally during a conversation

Real conversations do not always stay in one language.

A customer might begin a call in English, switch to French when discussing a specific topic, and then return to English later.

Lingua V2 is designed to handle these changes dynamically.

When a user changes their language during a call, the AI agent can switch languages and adapt its accent in real time, allowing the conversation to continue naturally without requiring the customer to restart the interaction or select a different agent.

The experience remains within the same conversation and context.

Language and accent working together

One of the core ideas behind Lingua V2 is that language and accent should not be treated as separate experiences.

The way a language sounds can be just as important as the words being spoken.

Lingua V2 combines multilingual speech generation with regional accent adaptation to create voice interactions that feel more natural across different markets.

Instead of simply asking, “Can the AI speak this language?”, businesses can think about a more important question:

Can the AI communicate naturally with customers who speak that language?

That is the experience Lingua V2 is designed to deliver.

Built for cross-lingual conversational AI

Lingua V2 is particularly suited to applications where customers and AI agents may communicate across multiple languages.

This includes:

The engine is designed to make multilingual conversations easier to build and deploy without requiring businesses to create separate voice experiences for every language.

Designed for agentic workflows

Lingua V2 also supports agentic workflows, where AI agents need to communicate naturally while completing tasks and taking actions.

A multilingual agent can maintain the conversation while interacting with business systems, handling requests, collecting information, booking appointments, or moving a customer through a workflow.

Language does not have to become a barrier between the customer and the task the agent is trying to complete.

Built for businesses without borders

Businesses increasingly operate across countries, languages, and customer communities.

For companies serving international customers, multilingual communication is no longer a niche requirement. It is part of everyday business.

29 languages. One conversation.

With Lingua V2, businesses can create AI voice experiences that support 29 languages, adapt to language changes during live conversations, and deliver regional accents designed to sound natural to the listener.

The objective is simple: make multilingual AI conversations feel less like translation and more like communication.
