Fraunhofer modular speech technology

Allinga provides you with all the necessary modules to configure a comprehensive and tailored voice assistant system.

With the modules already available, Allinga offers high-performance, AI-supported solutions for speech recognition and speech synthesis – all made in Germany. Both modules function autonomously but can also be seamlessly integrated into a reliable speech interface in an existing environment.

The Allinga engine uses Natural Language Understanding based on Deep Learning technologies and can reproduce business processes reliably. Allinga Architect is your tool for building your tailored voice assistant system in a simple and intuitive manner.

Speech recognition

Automatic Speech Recognition (ASR)

Technical systems that understand spoken commands enable natural communication between humans and machines. Allinga speech recognition reliably translates spoken information into digital text in real time, even under tough conditions, such as with background noise in industrial settings or if the user is speaking in regional dialect. This allows companies, for instance, to optimize services, to increase their efficiency or to offer completely new types of services.

Features

  • highly reliable speech recognition
  • excellent performance in German and English
  • robust against noise, e.g. in an industrial setting
  • retrainable for specific applications and specialized vocabulary
  • customizable, e.g. selectable wake word
  • integrated speaker recognition
  • word and phoneme output to subsequent systems

Speech synthesis

Text-to-Speech (TTS)

In human-machine interaction, it is often beneficial if textual information doesn’t need to be – for example from a display – but can instead be communicated via natural speech. Allinga Voice gives your devices and services a voice for the output of information and content. State-of-the-art algorithms use Deep-Learning technology to create very natural-sounding speech with excellent intelligibility and fluent intonation.

Allinga Architect

Allinga Architect will enable you to further personalize your voice assistant for specific applications, using an intuitive graphic user interface. Here, you can combine deterministic dialog graphs with dynamic dialog components, creating a reliable and intelligent assistant.

Allinga Engine

In recent years, there has been huge progress in the field of Deep Learning for Natural Language Understanding. Beyond the entertainment industry, however, there are important aspects to consider for professional, AI-based voice assistants. These include the requirement that decisions are explainable and reproducible, as well as a frequent lack of valid training data. Allinga Engine therefore follows an approach based on state-of-the-art Deep Learning technologies to achieve high-performance speech understanding while at the same time reliably reproducing business processes.

Allinga Engine facilitates flexible dialog with deterministic, reliable behavior on clearly defined paths, and masters dynamic dialog elements. The latter allows it to, for example, enter unordered information into forms and automatically request missing information.

With Allinga Engine, users can use natural speech to intuitively request information from external knowledge sources and databases. Allinga Engine utilizes information in existing knowledge representations to achieve this, for example, texts such as manuals or knowledge graphs. Allinga Engine also supports the creation of new knowledge graphs by combining heterogeneous company data.

Allinga Engine can carry out individual commands and connect external services. In this way, machines can be easily controlled or data entered into ERP systems using voice commands.
