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.
The basis of the robust, distant speech acquisition is the vicSBM developed by voice INTER connect - a SoC module for beamforming and beesmsteering for use in serial products. The extremely efficient algorithms of the vicMSES library are able to process up to 16 microphone channels and can be configured for specific applications via the UART interface. vicSBM provides an output signal of outstanding audio quality and high naturalness at the I2S interface - even if the microphone signals are strongly reverberated or noisy originally.
vicSBM provides standardized interfaces for connecting customer-specific microphone arrays, an LED display for signaling the speaker's position, for transferring the cleaned speech signal to the host system and for controlling signal acquisition. The module can also be used standalone, since the ARM Cortex A7 core of the Sharc processor is available for application development.
We also provide a development kit for evaluating your solution - vicDIVA is based on Raspberry PI 3 with a circular 7-microphone array and a vicSBM.
