👤 Who This is For
Use Case Scenarios
Hands-Free Voice Control for Multilingual Field Operations
Field engineers working in noisy, hazardous environments need to operate machinery, request manuals, or log incidents—all without taking off gloves or looking at a screen.
- Picovoice handles all commands locally, in real time, with no internet connection—even with gloves, noise, and regional accents.
- Fully on-device—meets industrial security requirements
- Works in offline or edge-only environments
- Adds contextual understanding to existing HMI systems
Multilingual Patient Intake
Clinics in large cities serve patients in their native language while healthcare professionals receive the medical information in a pre-determined language.
- Voicebot understands symptoms, triages severity, and routes to appropriate care—securely and offline.
- HIPAA/GDPR compliant—no audio leaves the clinic
- Localized intent recognition for medical vocabularies
- Speeds up triage and reduces human workload
Multilingual Voicebot for Enterprise Customer Service Hubs
Large enterprises operate global customer support centers where agents or automated systems must handle high call volumes from users in multiple languages. Instead of routing all calls to human agents or relying on cloud-based ASR, companies deploy on-device multilingual voicebots to handle Tier-1 queries securely and cost-effectively.
- The Picovoice-powered voicebot understands the intent locally and responds or routes to the appropriate workflow
Multilingual Voicebots for Ticketing & Transit Hubs
Train stations, metro systems, and event venues deploy voice-enabled kiosks that help users purchase tickets, check schedules, and get directions—in multiple languages and without needing to touch a screen.
- The on-device voicebot responds immediately, even in noisy, high-traffic environments—no cloud dependency, no network latency
Key benefits
- Improves accessibility for international and non-literate users
- Reduces agent load by 30–50% by automating common queries
- Enables touchless interaction in high-volume public spaces
- Handles accent variation, background noise, and fast-paced speech—intrinsically compliant with regulations
- Ensures data privacy
- Fast, edge-first response times, even in regions with poor connectivity

Frequently asked questions
Picovoice is designed to run on resource-constrained devices. Although minimum requirements depend on the technical stack and implementation, basic CPU capabilities found in most modern devices are sufficient. No specialized hardware is required.
Technically there is no limit on the number of languages used to create multilingual voice AI chatbots. For now, Picovoice offers out-of-the-box support for eight languages. If you have a use case requiring languages that are not currently supported, you can work with Picovoice Consulting once you become an Enterprise Plan customer.
Picovoice provides out-of-the-box support for eight languages. English, Spanish, French, German, Japanese, Korean, Italian and Portuguese. If you have a use case requiring languages that are not currently supported, you can work with Picovoice Consulting once you become an Enterprise Plan customer.
Picovoice offers state-of-the-art voice AI models with a high accuracy rate (90%+) across supported languages, dialects, and accents. Picovoice voice AI models are trained on real-world data and continuously improved to handle various speaking patterns, background noise, and conversational contexts.
Integration for PoC and demo purposes generally takes a few days, if not hours, depending on the complexity of the multilingual voice chatbots. Developing, testing, and iterating for production can take longer depending on the processes that each company needs to follow. Picovoice provides comprehensive documentation for each modern SDK (Web, React Native, iOS, Android, Linux, Windows, macOS), sample code, and enterprise-grade support to accelerate implementation.
Picovoice team closely monitors the market in order to offer the best-in-class voice AI technology with affordable prices to enable resilient or high-volume applications.
