Hi all, I'm new to voice recognition V3. The source of this module is quite limited. Can anyone tell me that does this module use HM2007 chip?
I don't think so.
The HM2007 requires an external SRAM (64k bits, 8kx8) and can recognize 40 words. The elechouse VoiceRecognitionV3 has the memory built in and can only recognize 7 words at a time (selected from an 80-word vocabulary).
Then, what is the theory behind. Its possible to find? Because I need to know what is the chip use, the recognition method use, detection method use, decoder and so on.
