NearSpeak is an interesting Near Field Communication (NFC) app for your Windows Phone 8 device that lets you record voice messages and store them on NFC tags.
There are a couple of neat aspects to NearSpeak. First, NFC tags typically lack the storage space to hold audio files. To record your voice, NearSpeak uses speech recognition to convert your spoken word into text. When played back, the text on the NFC tag is converted back to audio through NearSpeak's speech files.
