Picovoice Platform

Picovoice is the end-to-end platform for building voice products on your terms. Unlike Alexa and Google services, Picovoice runs entirely on-device while being more accurate. Using Picovoice, one can infer a user’s intent from a naturally spoken utterance such as:

Hey Edison, set the lights in the living room to blue.

Picovoice detects the occurrence of the custom wake word (Hey Edison), and then extracts the intent from the follow-on spoken command:

"intent": "changeLightColor",
"slots": {
"location": "living room",
"color": "blue"

Why Picovoice

  • Private & Secure: Everything is processed offline. Intrinsically private; HIPAA and GDPR compliant.
  • Accurate: Resilient to noise and reverberation. Outperforms cloud-based alternatives by wide margins.
  • Cross-Platform: Design once, deploy anywhere. Build using familiar languages and frameworks.
  • Self-Service: Design, train, and test voice interfaces instantly in your browser, using Picovoice Console.
  • Reliable: Runs locally without needing continuous connectivity.
  • Zero Latency: Edge-first architecture eliminates unpredictable network delay.

Build with Picovoice

  1. Evaluate: The Picovoice SDK is a cross-platform library for adding voice to anything. It includes some pre-trained speech models. The SDK is licensed under Apache 2.0 and available on GitHub to encourage independent benchmarking and integration testing. You are empowered to make a data-driven decision.

  2. Design: Picovoice Console is a cloud-based platform for designing voice interfaces and training speech models, all within your web browser. No machine learning skills are required. Simply describe what you need with text and export trained models.

  3. Develop: Exported models can run on Picovoice SDK without requiring constant connectivity. The SDK runs on a wide range of platforms and supports a large number of frameworks. The Picovoice Console and Picovoice SDK enable you to design, build and iterate fast.

  4. Deploy: Deploy at scale without having to maintain complex cloud infrastructure. Avoid unbounded cloud fees, limitations, and control imposed by big tech.

Platform Features

Custom Wake Words

Picovoice makes use of the Porcupine wake word engine to detect utterances of given wake phrases. You can train custom wake words using Picovoice Console and then run the exported wake word model on the Picovoice SDK.

Intent Inference

Picovoice relies on the Rhino Speech-to-Intent engine to directly infer user's intent from spoken commands within a given domain of interest (a "context"). You can design and train custom contexts for your product using Picovoice Console. The exported Rhino models then can run with the Picovoice SDK on any supported platform.

License & Terms

The Picovoice SDK is free and licensed under Apache 2.0 including the models released within. Picovoice Console offers two types of subscriptions: Personal and Enterprise. Personal accounts can train custom speech models that run on the Picovoice SDK, subject to limitations and strictly for non-commercial purposes. Personal accounts empower researchers, hobbyists, and tinkerers to experiment. Enterprise accounts can unlock all capabilities of Picovoice Console, are permitted for use in commercial settings, and have a path to graduate to commercial distribution.
