A robust, distant speech acquisition is a requirement for the use of voice control in smart homes, voice assistants or voice-controlled user interfaces for industrial plants and machines, as well as for modern communication systems.
voice INTER connect offers a dedicated library of algorithms (vicMSES) for these use cases. It allows for far-field acquisition of voice signals with highest quality. The algorithms can be arranged and parameterized to the customer's needs. This way, it is possible to control devices via voice even if they are several meters away and/or in the presence of simultaneous noises or several concurrent speakers.
This evaluation kit vicDIVA offers the possibility to configure the beamforming algorithms and test them in customer-specific applications. vicDIVA consists of a microphone array with 8 microphones and status LEDs, the hardware module vicSBM which is processing the microphone signals, and a Raspberry Pi that is used for application development and power supply. The improved audio signal is provided at the audio interface. The results can be evaluated via additional connected headphones.
