What Vivoka does

Vivoka is a French software company founded in 2015 and headquartered in Metz, that develops an embedded Voice AI platform — the Voice Development Kit (VDK) — designed to run entirely on edge devices without cloud connectivity. The VDK is an all-in-one software stack bundling Automatic Speech Recognition (ASR), Natural Language Understanding (NLU), Text-to-Speech (TTS), Wake Word activation, Voice Biometrics, and an Audio Front-End for noise handling, supporting 41 languages for ASR and 65 for TTS. The platform targets high-stakes industrial and regulated environments — principally logistics and warehousing, field services and MRO, and MedTech/healthcare — where connectivity is unreliable, data privacy is mandated, or sterile hands-free operation is required. Named deployments include Vuzix, SUEZ, KFI, Körber, Bcom, Epson, Rokid, Hubone, and Actor med.

The company's core technology differentiator is its privacy-first, offline architecture: voice data never leaves the device, enabling use cases in clinical, industrial, and enterprise settings where cloud-dependent voice AI is non-viable. VDK 6.3, released in June 2026, integrates Cerence's latest embedded neural ASR, deepening the company's ability to serve multilingual, accented, and noisy real-world environments. The platform is distributed through direct enterprise sales, an OEM/embedded licensing model, and a partner ecosystem including Cerence, BdSound, ID R&D, Sensory, Witekio, Zebra Technologies, and ITOS Technology. Vivoka reports 90+ customers across more than 20 countries, with a team of approximately 40 employees, the majority of whom are PhDs and senior engineers.

Vivoka generates revenue primarily through per-unit royalty-based licensing for hardware-integrated deployments, complemented by subscription alternatives and professional services for integration, scoping, and customization. The company offers a 30-day evaluation period for prospects and supports both perpetual one-time licenses and annual subscriptions. Regional presence includes France (HQ), Italy, Germany, and Belgium, supporting European enterprise sales with OEM channels extending reach into global industrial markets. The company has been bootstrapped with limited disclosed outside capital — one equity round of approximately €1.1M in February 2018 from Bpifrance and Groupe Etchart — and remains privately held under VIVOKA SAS.

Revenue model

1. VDK Licensing (Royalty-based): Fixed-price VDK with add-on resources and technologies. Commercial exploitation uses a royalty-based licensing model where customers pay a specific price per unit equipped with Vivoka's technologies. This is the primary revenue model for hardware-integrated deployments.
2. Subscription Model: Flexible subscription models available that can apply to existing pricing structures. Offered as an alternative to the per-unit royalty model for customers preferring recurring payments.
3. Professional Services: Support and customization services including project scoping, integration assistance, and training. Vivoka offers evaluation periods and expert guidance throughout the customer journey.

• Microsoft (Nuance): Nuance (now under Microsoft) provides Dragon and clinical voice-AI solutions for healthcare, enterprise and customer engagement, representing a much larger incumbent competing in MedTech and enterprise voice where Vivoka also sells.

Direct peers

• Sensory: Sensory licenses embedded AI for wake word, small/large vocabulary speech recognition and NLU into consumer and enterprise devices. It is both a Vivoka technology partner and a direct comparable in embedded voice SDKs.
• Picovoice: Picovoice builds on-device voice AI (Leopard speech recognition, Cheetah STT, Koala noise suppression) with a similar privacy-first, edge-deployment stance targeting enterprise and developer use cases, directly comparable to Vivoka's VDK approach.
• ReadSpeaker: ReadSpeaker is a text-to-speech and voice AI vendor offering enterprise and embedded voices in many languages, overlapping with Vivoka's TTS capabilities and multi-language support.
• SoundHound: SoundHound provides a voice AI platform spanning speech recognition, NLU and conversational AI for automotive, restaurants and enterprise IVR, with comparable enterprise voice-AI ambitions and SDK-style integration.
• Kardome: Kardome offers on-device, speaker-separated voice AI and noise-robust speech recognition for automotive, smart home, and IoT, competing with Vivoka's Audio Front-End and ASR stack in edge-voice deployments.

Emerging players

• Speechmatics: Speechmatics provides ASR and voice technology with a strong emphasis on multi-language accuracy, comparable to Vivoka's 41-language ASR footprint in enterprise and contact-center deployments.
• AssemblyAI: AssemblyAI offers cloud speech recognition and audio intelligence APIs, representing an emerging developer-focused voice AI platform that competes for the same enterprise AI budgets as Vivoka's VDK.
• Deepgram: Deepgram provides cloud-based speech-to-text and voice AI APIs for enterprise developers. It is a comparable in the voice AI tooling category but cloud-only, contrasting with Vivoka's edge focus.
