Ivan Holland over at CPC Maker Space has done a great write-up of this little board that gives your Raspberry Pi ears. He takes you through the steps of installing the software necessary to use Google Voice Services. This makes the pHAT a great, smaller alternative to Google’s own AIY Voice kit. You can read the tutorial here. You can get the Re-Speaker 2-Mics pHAT from CPC or from Seeed Studio, the original makers.
