Frequently asked questions

How fast is the translation between languages?

Picovoice delivers real-time, sub-second translation speeds by using on-device processing and compact large language models (LLMs). Unlike cloud-based solutions, there's no delay from server round-trips, which makes live conversations feel smooth and natural. Whether switching between English and Spanish or Korean and French, the speed supports truly fluid multilingual interaction.

Can it handle domain-specific language, like medical or legal terms?

Yes. Complete technological ownership enables fine-tuning at every layer rather than being constrained by third-party frameworks and pre-trained models. If you're interested in recognizing and translating specialized vocabulary in fields like medicine, law, or manufacturing, engage with Picovoice Consulting. Custom translation models will ensure accurate handling of technical terminology that generic translation engines often miss, making the tool suitable for enterprise, clinical, and regulated environments.

Does this work offline, even in areas with no internet?

Yes. The translation engine operates fully on-device—no cloud or internet is required for real-time usage. Whether offline in remote areas or inside secure environments, it works reliably. Note: Internet is only required for licensing and usage tracking.

Is it private? Where does voice data go?

All processing occurs locally on the device—voice, text, and translations are not transmitted to external servers. This ensures conversations remain secure and aligned with privacy standards. It's well-suited for sensitive use cases like telehealth and legal interpretation.

Does it support multiple language pairs?

Yes. Picovoice offers live translation across a wide range of languages and dialects, with the ability to expand to new language pairs as needed. If you require a language that Picovoice doesn't currently support, please reach out to your Picovoice representative to work with Picovoice Consulting.

What hardware is required?

Picovoice is optimized to run on across all platforms including smartphones, tablets, laptops, and embedded edge devices. Check out Picovoice Docs for more information.
