DSPs for voice UI, control and audio and speech processing
TI has developed a flexible platform for voice processing on DSPs which work with multiple microphone configurations to help enable voice recognition in voice assistant applications. Field hardened algorithms for beamforming, noise reduction, dynamic range control and more are available in working project examples for evaluation and development. The software application is built on TI’s Processor SDK, allowing product choice and easy migration among TI’s processor portfolio.
TI’s audio pre-processing systems designs allow for easy evaluation and development of a DSP based application for far-field voice processing. Using field hardened, TI developed algorithms for beam-forming, noise reduction and other technologies, these designs show reference examples using different microphone array combinations to acquire the voice signal. The reference design also includes GUI based tools for calculating filter coefficients and easily configuring the input parameters to the DSP based on the microphone count and array geometry used.
