1D VEP – Linear Microphone Array
A new linear microphone array iteration of Alango’s Voice Enhancement Package (VEP), which functions as an ASR pre-processor, has been released. The previous iteration of VEP – utilizing 2D microphone array beamforming - targets smart speaker applications. The new “1D VEP”, typically with 4 or more microphones positioned in one line, includes stereo acoustic echo cancellation and far-field beamforming – with auxiliary tools for direction extrapolation. 1D VEP is particularly suitable for implementation in a voice controlled TV, especially since the geometry of a TV does not typically lend itself to accommodate placement of a 2D microphone array.
