Industry proven

The VoCon^® product family has delivered the power of speech to consumer and industrial products for over 10 years.

Enhanced experience

VoCon Hybrid delivers a new level of speaker-independent and continuous speech recognition as well as multi-lingual language understanding.

Total hybrid solution

Full range of embedded and connected speech recognition services from embedded digit recognition to connected dictation and complex search functionality. Embedded failsafe for many use cases if network connectivity is lost.

Highly compatible

VoCon Hybrid can be combined with other solutions in the VoCon product family or Vocalizer's text-to-speech for a more robust speech dialogue solution and improved accuracy.

Industrial

VoCon Hybrid is used in a wide variety of industrial applications in warehousing and distribution equipment as well as medical equipment.

User experience

Voice options that give you all the control

High accuracy in noisy environments

VoCon Hybrid is developed for mobile applications with high accuracy operation to SNR levels as low as 5dB.

Natural language understanding (NLU)

Recognises natural speech, eliminating restriction to predefined commands for all VoCon Hybrid languages.

All-inclusive main menu (a1M)

Enables all commands to be spoken in a single utterance on the main menu.

Extensive global language portfolio

Worldwide support for over 30 languages provides universal functionality.

Large vocabulary support

Enables embedded recognition for large lists with connected dictation and search capabilities.

Wake-up word

Always listening mode allows the user to “wake up” or activate their system with a keyword, such as “Hello Dragon”. Removes the need for a press-to-talk button.

Barge-in

Talk over barge-in allows user to speak over spoken dialogue prompts and be recognised.

Large related list support

Enables recognition from combined large lists recognising only valid combinations, such as street + city + state for all USA, or part + warehouse combinations.

Flexible phone book selection

Recognises partial contact names for multi-lingual phonebooks.

Spelling module

Spelling module available as backup to whole word recognition.

Bandwidth extension for 8kHz signals

Whenever 8kHz audio input is the only available format, such as Bluetooth, it is now possible to recognise 8kHz audio input with standard 16kHz acoustic models.

Hardware acceleration

Supports Spansion and Neon Expansions to improve the operation point of the speech recognition both in terms of speed and accuracy by shifting a part of the algorithmic processing to dedicated hardware.

Fuzzy match technology for POI search

Recognises every possible word in a database in every possible order and permutation, including partial utterances. This search algorithm is especially useful when the user does not know the exact wording of the content he or she is searching for.

Software Development Kits (SDK)

Robust tools. Amazing possibilities.

VoCon^® Hybrid Engine

Gain exceptional recognition accuracy tuned for noisy automotive environments. VoCon Hybrid Engine delivers a superior user experience and high acceptance rates across a wide variety of in-vehicle systems and applications. Continuous improvements of the speech algorithms ensure the highest accuracy standards, even for large and complex tasks.

VoCon^® Hybrid Software Development Kit

Adds speech recognition functionality to any application. Includes VoCon^® Hybrid speech recognition engine, a robust set of development tools, guides and sample code that allow developers to build a high-quality speech-enabled application with optimum speed and efficiency.

VoCon Hybrid SDK is available in two variants that use the same API:

Enables embedded recognition for large lists with connected dictation and search capabilities.

Basic SDK

Provides Nuance's state-of-the-art VoCon technology for embedded speech recognition and voice barge-in. This is recommended for embedded-only applications with no requirement for connected speech recognition while offering the flexibility to add connected speech recognition later.

Connected SDK

Provides access to Nuance's Dragon connected speech services in the network in addition to state-of-the-art VoCon technology for embedded speech recognition and voice barge-in. Connected services are available through the NDEV community powered by Dragon.

NDEV Community

Platform support

Customise. Optimise. Mobilise.

Scalable, modular architecture

Supports a range of operating points so that smaller applications are not affected by higher CPU and RAM required for larger applications.

VoCon Hybrid supports:

Android
iOS (iPhone)
Linux (Ubuntu), (PC & ARM)
Windows XP & Windows 7 operating systems

The software interface in the Windows SDK is identical to the interface once ported to an embedded platform allowing code built on the PC to be reused on the platform.

Additional speech solutions

But wait, there's more

VoCon^® Music Premium Add-On

Nuance, in partnership with Gracenote, provides the capability to retrieve precompiled and editorially checked phonetics for artist and album names, alternative names and/or artist nicknames from regularly updated dictionaries. VoCon Music Premium requires VoCon Hybrid (Base) on platform and can be used with ASR and TTS solutions.

Vocalizer Expressive

Text-to-speech solution that enriches the user experience with enhanced expressivity by generating high-quality and natural-sounding speech.

VoCon^® Speech Signal Enhancement (SSE)

A suite of technologies that work together to remove noise from microphone input and send out a cleaner signal.
