voice INTER connect GmbH

vicCONTROL DSP 3 stamp is an extension board, with which your existing product can be extended by a voice control. Unlike Amazon Alexa or Google Home, local speech recognition takes place without an internet connection. This way, your speech data remains protected and is not stored on central servers. Even critical functions (e. g. opening windows can be operated safely via voice control. The reasonably priced SoC module is optimally suited for series production and is available in the long term.

Product Features

- Small, low-cost SoC module for voice control, designed for series production

- Natural language voice control for technical devices

- Flexible, speaker-independent vocabulary

- Currently available in 30 languages

- High robustness even in noisy environments

- Acoustic feedback

- Freely programmable digital inputs and outputs

- Serial protocol

- Ready for connection of digital (interference-free) microphones

Areas of Application

- Intelligent home automation

- Control of machines and equipments

- Geriatric care and rehabilitation technology

- Fast media access

- Interaction with consumer and kitchen appliances

Intercom Module for Hands-free Communication

Thanks to patented algorithms for acoustic echo cancellation (AEC) and noise reduction (NR), the vicCOM 2 audio processing modules enable excellent audio quality and speech intelligibility at the highest level – even under difficult environmental conditions.

The modules can be integrated as a component into customer-specific layouts or into existing devices. The scope of delivery includes signal processing software and analog audio connections.

- Intelligent loss control

- Signal conditioning for microphone and loudspeaker (compressor, limiter, noise gate, equaliser, notch filter)

- Level adjustment to signal sources and sinks

- Management of different parameter sets

- ASCII and binary protocol for setting parameters at runtime

- Multimedia bandwidth with sampling frequency up to 16 kHz

- Playback and management of audio files (e. g. ring tones) up to a total playing time of approximately 230 s

- Software can be updated

Hardware:

- Circuit board with edge contacts

- Small dimensions (60 x 30 x 4 mm)

- Extended temperatur range (- 40 up to 85 degrees Celsius)

- Pin-compatible to vicCOM of the first generation

The vicCONTROL industrial is a further development of the successful vicCONTROL voice control for ARMv7 compatible platforms. Due to the increased computing power of the ARM processors and their widespread use in devices and machine controls, vicCONTROL industrial can be used directly without additional hardware. Using our design tool vicDT-Dialogue Designer, the development of a customer-specific voice control application with the vicCONTROL industrial is easier than ever. Integration with the existing control application is carried out via the IoT protocol MQTT.
Since vicCONTROL industrial does not require an internet connection and voice control is implemented locally on the ARM processor, it is particularly suitable for applications that are sensitive to internet access or data protection. In terms of performance, vicCONTROL industrial stands out the cloud-based speech recognizers such as Amazon's Alexa or Google Home in no way. Besides, vicCONTROL industrial is available in 30 languages.

Product Features

• SDK for embedded ARMv7 compatible platforms
• Convenient API for using voice input and output functions via MQTT
• vicDT-Dialogue Designer with examples for the development of a customer-specific voice control system
• Industry-proven quality in 30 languages
• Wake-up word function
• Semantic evaluation for the recognized voice commands

Application Areas

• Extension of GUIs with voice control
• Control of machines and appliances
• Operation and monitoring of medical systems
• Intuitive input in rehabilitation technology
• Natural collaboration with robots and in AR applications
• Self-explanatory user interfaces

A robust, distant speech acquisition is a requirement for the use of voice control in the Smart Home, voice assistants or voice-controlled user interfaces of industrial plants and machines.
voice INTER connect offers vicDIVA (Distant Voice Acquisition Solution) especially for this use case - a solution for recording voice in room. This makes it possible to control devices several meters away by voice, even with simultaneous noise or several speakers.
The vicDIVA development kit offers the possibility of configuring beamforming procedures individually and testing them for a specific application. vicDIVA consists of a customized microphone array with up to 7 microphones and status LEDs, the hardware module vicSBM for processing up to 7 microphone signals, and a host platform (Raspberry PI 3) for application development, which supplies power to the vicSBM and provides the cleaned audio signal over an audio interface for your application. An example application on the Raspberry PI allows the subjective evaluation of the output signal of the beamformer via connected headphones and the configuration of the beamforming algorithms on the vicSBM via the console. For evaluation purposes, the kit is provided with a circular 7-microphone array.

Product Features

• Development kit for evaluation of beamforming algorithms and individual microphone arrays
• Robust distant voice acquisition
• Suppression of room influences such as reverberation and noise
• Positioning and display of the speaker
• Tracking a speaker in the room

Applications

• Voice-controlled devices and industrial machines
• Voice control in Smart Homes
• Speech assistants
• Intercom systems in industrial environments
• Video conferencing
• Acoustic monitoring of rooms
