This training identifies the hardware components required to build an application with voice recognition capability, including C55x, C674x, K2Gx, OMAP-L137, PCM186x, TAS5760M, TPA3136D2, TAS2555, and TLV320DAC3203. It describes the criteria for matching devices to application requirements, such the number of mics (ADC choice, DSP MIPS needed), pre- and post-processing features (DSP MIPS), and power required for audio output (which amp to use).
